How do I do a SELECT * INTO [temp table] FROM [stored procedure]? Not FROM [Table] and without defining [temp table]?
Select all data from BusinessLine into tmpBusLine works fine.
select *
into tmpBusLine
from BusinessLine
I am trying the same, but using a stored procedure that returns data, is not quite the same.
select *
into tmpBusLine
from
exec getBusinessLineHistory '16 Mar 2009'
Output message:
Msg 156, Level 15, State 1, Line 2
Incorrect syntax near the keyword
'exec'.
I have read several examples of creating a temporary table with the same structure as the output stored procedure, which works fine, but it would be nice to not supply any columns.
You can use OPENROWSET for this. Have a look. I've also included the sp_configure code to enable Ad Hoc Distributed Queries, in case it isn't already enabled.
CREATE PROC getBusinessLineHistory
AS
BEGIN
SELECT * FROM sys.databases
END
GO
sp_configure 'Show Advanced Options', 1
GO
RECONFIGURE
GO
sp_configure 'Ad Hoc Distributed Queries', 1
GO
RECONFIGURE
GO
SELECT * INTO #MyTempTable FROM OPENROWSET('SQLNCLI', 'Server=(local)\SQL2008;Trusted_Connection=yes;',
'EXEC getBusinessLineHistory')
SELECT * FROM #MyTempTable
If you want to do it without first declaring the temporary table, you could try creating a user-defined function rather than a stored procedure and make that user-defined function return a table. Alternatively, if you want to use the stored procedure, try something like this:
CREATE TABLE #tmpBus
(
COL1 INT,
COL2 INT
)
INSERT INTO #tmpBus
Exec SpGetRecords 'Params'
In SQL Server 2005 you can use INSERT INTO ... EXEC to insert the result of a stored procedure into a table. From MSDN's INSERT documentation (for SQL Server 2000, in fact):
--INSERT...EXECUTE procedure example
INSERT author_sales EXECUTE get_author_sales
This is an answer to a slightly modified version of your question. If you can abandon the use of a stored procedure for a user-defined function, you can use an inline table-valued user-defined function. This is essentially a stored procedure (will take parameters) that returns a table as a result set; and therefore will place nicely with an INTO statement.
Here's a good quick article on it and other user-defined functions. If you still have a driving need for a stored procedure, you can wrap the inline table-valued user-defined function with a stored procedure. The stored procedure just passes parameters when it calls select * from the inline table-valued user-defined function.
So for instance, you'd have an inline table-valued user-defined function to get a list of customers for a particular region:
CREATE FUNCTION CustomersByRegion
(
#RegionID int
)
RETURNS TABLE
AS
RETURN
SELECT *
FROM customers
WHERE RegionID = #RegionID
GO
You can then call this function to get what your results a such:
SELECT * FROM CustomersbyRegion(1)
Or to do a SELECT INTO:
SELECT * INTO CustList FROM CustomersbyRegion(1)
If you still need a stored procedure, then wrap the function as such:
CREATE PROCEDURE uspCustomersByRegion
(
#regionID int
)
AS
BEGIN
SELECT * FROM CustomersbyRegion(#regionID);
END
GO
I think this is the most 'hack-less' method to obtain the desired results. It uses the existing features as they were intended to be used without additional complications. By nesting the inline table-valued user-defined function in the stored procedure, you have access to the functionality in two ways. Plus! You have only one point of maintenance for the actual SQL code.
The use of OPENROWSET has been suggested, but this is not what the OPENROWSET function was intended to be used for (From Books Online):
Includes all connection information
that is required to access remote data
from an OLE DB data source. This
method is an alternative to accessing
tables in a linked server and is a
one-time, ad hoc method of connecting
and accessing remote data by using OLE
DB. For more frequent references to
OLE DB data sources, use linked
servers instead.
Using OPENROWSET will get the job done, but it will incur some additional overhead for opening up local connections and marshalling data. It also may not be an option in all cases since it requires an ad hoc query permission which poses a security risk and therefore may not be desired. Also, the OPENROWSET approach will preclude the use of stored procedures returning more than one result set. Wrapping multiple inline table-value user-defined functions in a single stored procedure can achieve this.
Select ##ServerName
EXEC sp_serveroption ##ServerName, 'DATA ACCESS', TRUE
SELECT *
INTO #tmpTable
FROM OPENQUERY(YOURSERVERNAME, 'EXEC db.schema.sproc 1')
Easiest Solution:
CREATE TABLE #temp (...);
INSERT INTO #temp
EXEC [sproc];
If you don't know the schema then you can do the following. Please
note that there are severe security risks in this method.
SELECT *
INTO #temp
FROM OPENROWSET('SQLNCLI',
'Server=localhost;Trusted_Connection=yes;',
'EXEC [db].[schema].[sproc]')
When the stored procedure returns a lot of columns and you do not want to manually "create" a temporary table to hold the result, I've found the easiest way is to go into the stored procedure and add an "into" clause on the last select statement and add 1=0 to the where clause.
Run the stored procedure once and go back and remove the SQL code you just added. Now, you'll have an empty table matching the stored procedure's result. You could either "script table as create" for a temporary table or simply insert directly into that table.
declare #temp table
(
name varchar(255),
field varchar(255),
filename varchar(255),
filegroup varchar(255),
size varchar(255),
maxsize varchar(255),
growth varchar(255),
usage varchar(255)
);
INSERT #temp Exec sp_helpfile;
select * from #temp;
If the results table of your stored proc is too complicated to type out the "create table" statement by hand, and you can't use OPENQUERY OR OPENROWSET, you can use sp_help to generate the list of columns and data types for you. Once you have the list of columns, it's just a matter of formatting it to suit your needs.
Step 1: Add "into #temp" to the output query (e.g. "select [...] into #temp from [...]").
The easiest way is to edit the output query in the proc directly. if you can't change the stored proc, you can copy the contents into a new query window and modify the query there.
Step 2: Run sp_help on the temp table. (e.g. "exec tempdb..sp_help #temp")
After creating the temp table, run sp_help on the temp table to get a list of the columns and data types including the size of varchar fields.
Step 3: Copy the data columns & types into a create table statement
I have an Excel sheet that I use to format the output of sp_help into a "create table" statement. You don't need anything that fancy, just copy and paste into your SQL editor. Use the column names, sizes, and types to construct a "Create table #x [...]" or "declare #x table [...]" statement which you can use to INSERT the results of the stored procedure.
Step 4: Insert into the newly created table
Now you'll have a query that's like the other solutions described in this thread.
DECLARE #t TABLE
(
--these columns were copied from sp_help
COL1 INT,
COL2 INT
)
INSERT INTO #t
Exec spMyProc
This technique can also be used to convert a temp table (#temp) to a table variable (#temp). While this may be more steps than just writing the create table statement yourself, it prevents manual error such as typos and data type mismatches in large processes. Debugging a typo can take more time than writing the query in the first place.
Does your stored procedure only retrieve the data or modify it too? If it's used only for retrieving, you can convert the stored procedure into a function and use the Common Table Expressions (CTEs) without having to declare it, as follows:
with temp as (
select * from dbo.fnFunctionName(10, 20)
)
select col1, col2 from temp
However, whatever needs to be retrieved from the CTE should be used in one statement only. You cannot do a with temp as ... and try to use it after a couple of lines of SQL. You can have multiple CTEs in one statement for more complex queries.
For example,
with temp1020 as (
select id from dbo.fnFunctionName(10, 20)
),
temp2030 as (
select id from dbo.fnFunctionName(20, 30)
)
select * from temp1020
where id not in (select id from temp2030)
If the OPENROWSET is causing you issues, there is another way from 2012 onwards; make use of sys.dm_exec_describe_first_result_set_for_object, as mentioned here: Retrieve column names and types of a stored procedure?
First, create this stored procedure to generate the SQL for the temporary table:
CREATE PROCEDURE dbo.usp_GetStoredProcTableDefinition(
#ProcedureName nvarchar(128),
#TableName nvarchar(128),
#SQL nvarchar(max) OUTPUT
)
AS
SET #SQL = 'CREATE TABLE ' + #tableName + ' ('
SELECT #SQL = #SQL + '['+name +'] '+ system_type_name +'' + ','
FROM sys.dm_exec_describe_first_result_set_for_object
(
OBJECT_ID(#ProcedureName),
NULL
);
--Remove trailing comma
SET #SQL = SUBSTRING(#SQL,0,LEN(#SQL))
SET #SQL = #SQL +')'
To use the procedure, call it in the following way:
DECLARE #SQL NVARCHAR(MAX)
exec dbo.usp_GetStoredProcTableDefinition
#ProcedureName='dbo.usp_YourProcedure',
#TableName='##YourGlobalTempTable',#SQL = #SQL OUTPUT
INSERT INTO ##YourGlobalTempTable
EXEC [dbo].usp_YourProcedure
select * from ##YourGlobalTempTable
Note that I'm using a global temporary table. That's because using EXEC to run the dynamic SQL creates its own session, so an ordinary temporary table would be out of scope to any subsequent code. If a global temporary table is a problem, you can use an ordinary temporary table, but any subsequent SQL would need to be dynamic, that is, also executed by the EXEC statement.
Quassnoi put me most of the way there, but one thing was missing:
****I needed to use parameters in the stored procedure.****
And OPENQUERY does not allow for this to happen:
So I found a way to work the system and also not have to make the table definition so rigid, and redefine it inside another stored procedure (and of course take the chance it may break)!
Yes, you can dynamically create the table definition returned from the stored procedure by
using the OPENQUERY statement with bogus varaiables (as long the NO RESULT SET returns the
same number of fields and in the same position as a dataset with good data).
Once the table is created, you can use exec stored procedure into the temporary table all day long.
And to note (as indicated above) you must enable data access,
EXEC sp_serveroption 'MYSERVERNAME', 'DATA ACCESS', TRUE
Code:
declare #locCompanyId varchar(8)
declare #locDateOne datetime
declare #locDateTwo datetime
set #locDateOne = '2/11/2010'
set #locDateTwo = getdate()
--Build temporary table (based on bogus variable values)
--because we just want the table definition and
--since openquery does not allow variable definitions...
--I am going to use bogus variables to get the table defintion.
select * into #tempCoAttendanceRpt20100211
FROM OPENQUERY(DBASESERVER,
'EXEC DATABASE.dbo.Proc_MyStoredProc 1,"2/1/2010","2/15/2010 3:00 pm"')
set #locCompanyId = '7753231'
insert into #tempCoAttendanceRpt20100211
EXEC DATABASE.dbo.Proc_MyStoredProc #locCompanyId,#locDateOne,#locDateTwo
set #locCompanyId = '9872231'
insert into #tempCoAttendanceRpt20100211
EXEC DATABASE.dbo.Proc_MyStoredProc #locCompanyId,#locDateOne,#locDateTwo
select * from #tempCoAttendanceRpt20100211
drop table #tempCoAttendanceRpt20100211
Thanks for the information which was provided originally...
Yes, finally I do not have to create all these bogus (strict) table defintions when using data from
another stored procedure or database, and yes you can use parameters too.

Update: this will not work with temporary tables so I had to resort to manually creating the temporary table.
Bummer notice: this will not work with temporary tables, http://www.sommarskog.se/share_data.html#OPENQUERY
Reference: The next thing is to define LOCALSERVER. It may look like a keyword in the example, but it is in fact only a name. This is how you do it:
sp_addlinkedserver #server = 'LOCALSERVER', #srvproduct = '',
#provider = 'SQLOLEDB', #datasrc = ##servername
To create a linked server, you must have the permission ALTER ANY SERVER, or be a member of any of the fixed server roles sysadmin or setupadmin.
OPENQUERY opens a new connection to SQL Server. This has some implications:
The procedure that you call with OPENQUERY cannot refer temporary tables created in the current connection.
The new connection has its own default database (defined with sp_addlinkedserver, default is master), so all object specification must include a database name.
If you have an open transaction and are holding locks when you call OPENQUERY, the called procedure can not access what you lock. That is, if you are not careful you will block yourself.
Connecting is not for free, so there is a performance penalty.
If you're lucky enough to have SQL 2012 or higher, you can use dm_exec_describe_first_result_set_for_object
I have just edited the sql provided by gotqn. Thanks gotqn.
This creates a global temp table with name same as procedure name. The temp table can later be used as required. Just don't forget to drop it before re-executing.
declare #procname nvarchar(255) = 'myProcedure',
#sql nvarchar(max)
set #sql = 'create table ##' + #procname + ' ('
begin
select #sql = #sql + '[' + r.name + '] ' + r.system_type_name + ','
from sys.procedures AS p
cross apply sys.dm_exec_describe_first_result_set_for_object(p.object_id, 0) AS r
where p.name = #procname
set #sql = substring(#sql,1,len(#sql)-1) + ')'
execute (#sql)
execute('insert ##' + #procname + ' exec ' + #procname)
end
This stored proc does the job:
CREATE PROCEDURE [dbo].[ExecIntoTable]
(
#tableName NVARCHAR(256),
#storedProcWithParameters NVARCHAR(MAX)
)
AS
BEGIN
DECLARE #driver VARCHAR(10)
DECLARE #connectionString NVARCHAR(600)
DECLARE #sql NVARCHAR(MAX)
DECLARE #rowsetSql NVARCHAR(MAX)
SET #driver = '''SQLNCLI'''
SET #connectionString =

CAST(SERVERPROPERTY('ServerName') AS NVARCHAR(256)) +
COALESCE('\' + CAST(SERVERPROPERTY('InstanceName') AS NVARCHAR(256)), '') +

SET #rowsetSql = '''EXEC ' + REPLACE(#storedProcWithParameters, '''', '''''') + ''''
SET #sql = '
SELECT
*

FROM
OPENROWSET(' + #driver + ',' + #connectionString + ',' + #rowsetSql + ')'
EXEC (#sql)
END

It's a slight rework of this: Insert stored procedure results into table so that it actually works.
If you want it to work with a temporary table then you will need to use a ##GLOBAL table and drop it afterwards.
In order to insert the first record set of a stored procedure into a temporary table you need to know the following:
only the first row set of the stored procedure can be inserted into a temporary table
the stored procedure must not execute dynamic T-SQL statement (sp_executesql)
you need to define the structure of the temporary table first
The above may look as limitation, but IMHO it perfectly makes sense - if you are using sp_executesql you can once return two columns and once ten, and if you have multiple result sets, you cannot insert them into several tables as well - you can insert maximum in two table in one T-SQL statement (using OUTPUT clause and no triggers).
So, the issue is mainly how to define the temporary table structure before performing the EXEC ... INTO ... statement.
sys.dm_exec_describe_first_result_set_for_object
sys.dm_exec_describe_first_result_set
sp_describe_first_result_set
The first works with OBJECT_ID while the second and the third works with Ad-hoc queries as well. I prefer to use the DMV instead of the sp as you can use CROSS APPLY and build the temporary table definitions for multiple procedures at the same time.
SELECT p.name, r.*
FROM sys.procedures AS p
CROSS APPLY sys.dm_exec_describe_first_result_set_for_object(p.object_id, 0) AS r;
Also, pay attention to the system_type_name field as it can be very useful. It stores the column complete definition. For, example:
smalldatetime
nvarchar(max)
uniqueidentifier
nvarchar(1000)
real
smalldatetime
decimal(18,2)
and you can use it directly in most of the cases to create the table definition.
So, I think in most of the cases (if the stored procedure match certain criteria) you can easily build dynamic statements for solving such issues (create the temporary table, insert the stored procedure result in it, do what you need with the data).
Note, that the objects above fail to define the first result set data in some cases like when dynamic T-SQL statements are executed or temporary tables are used in the stored procedure.
I'm creating a table with the following schema and data.
Create a stored procedure.
Now I know what the result of my procedure is, so I am performing the following query.
CREATE TABLE [dbo].[tblTestingTree](
[Id] [int] IDENTITY(1,1) NOT NULL,
[ParentId] [int] NULL,
[IsLeft] [bit] NULL,
[IsRight] [bit] NULL,
CONSTRAINT [PK_tblTestingTree] PRIMARY KEY CLUSTERED
(
[Id] ASC
) WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
SET IDENTITY_INSERT [dbo].[tblTestingTree] ON
INSERT [dbo].[tblTestingTree] ([Id], [ParentId], [IsLeft], [IsRight]) VALUES (1, NULL, NULL, NULL)
INSERT [dbo].[tblTestingTree] ([Id], [ParentId], [IsLeft], [IsRight]) VALUES (2, 1, 1, NULL)
INSERT [dbo].[tblTestingTree] ([Id], [ParentId], [IsLeft], [IsRight]) VALUES (3, 1, NULL, 1)
INSERT [dbo].[tblTestingTree] ([Id], [ParentId], [IsLeft], [IsRight]) VALUES (4, 2, 1, NULL)
INSERT [dbo].[tblTestingTree] ([Id], [ParentId], [IsLeft], [IsRight]) VALUES (5, 2, NULL, 1)
INSERT [dbo].[tblTestingTree] ([Id], [ParentId], [IsLeft], [IsRight]) VALUES (6, 3, 1, NULL)

INSERT [dbo].[tblTestingTree] ([Id], [ParentId], [IsLeft], [IsRight]) VALUES (10, 5, 1, NULL)
SET IDENTITY_INSERT [dbo].[tblTestingTree] OFF
VALUES (10, 5, 1, NULL)
SET IDENTITY_INSERT [dbo].[tblTestingTree] On
create procedure GetDate
as
begin
select Id,ParentId from tblTestingTree
end
create table tbltemp
(
id int,
ParentId int
)
insert into tbltemp
exec GetDate
select * from tbltemp;
If the query doesn't contain parameter, use OpenQuery else use OpenRowset.
Basic thing would be to create schema as per stored procedure and insert into that table. e.g.:
DECLARE #abc TABLE(
RequisitionTypeSourceTypeID INT
, RequisitionTypeID INT
, RequisitionSourcingTypeID INT
, AutoDistOverride INT
, AllowManagerToWithdrawDistributedReq INT
, ResumeRequired INT
, WarnSupplierOnDNRReqSubmission INT
, MSPApprovalReqd INT
, EnableMSPSupplierCounterOffer INT
, RequireVendorToAcceptOffer INT
, UseCertification INT
, UseCompetency INT
, RequireRequisitionTemplate INT
, CreatedByID INT
, CreatedDate DATE
, ModifiedByID INT
, ModifiedDate DATE
, UseCandidateScheduledHours INT
, WeekEndingDayOfWeekID INT
, AllowAutoEnroll INT
)
INSERT INTO #abc
EXEC [dbo].[usp_MySp] 726,3
SELECT * FROM #abc
Code
CREATE TABLE #T1
(
col1 INT NOT NULL,
col2 NCHAR(50) NOT NULL,
col3 TEXT NOT NULL,
col4 DATETIME NULL,
col5 NCHAR(50) NULL,
col6 CHAR(2) NULL,
col6 NCHAR(100) NULL,
col7 INT NULL,
col8 NCHAR(50) NULL,
col9 DATETIME NULL,
col10 DATETIME NULL
)
DECLARE #Para1 int
DECLARE #Para2 varchar(32)
DECLARE #Para3 varchar(100)
DECLARE #Para4 varchar(15)
DECLARE #Para5 varchar (12)
DECLARE #Para6 varchar(1)
DECLARE #Para7 varchar(1)
SET #Para1 = 1025
SET #Para2 = N'6as54fsd56f46sd4f65sd'
SET #Para3 = N'XXXX\UserName'
SET #Para4 = N'127.0.0.1'
SET #Para5 = N'XXXXXXX'
SET #Para6 = N'X'
SET #Para7 = N'X'
INSERT INTO #T1
(
col1,
col2,
col3,
col4,
col5,
col6,
col6,
col7,
col8,
col9,
col10,
)
EXEC [dbo].[usp_ProcedureName] #Para1, #Para2, #Para3, #Para4, #Para5, #Para6, #Para6
I hope this helps. Please qualify as appropriate.
I found Passing Arrays/DataTables into Stored Procedures which might give you another idea on how you might go solving your problem.
The link suggests to use an Image type parameter to pass into the stored procedure. Then in the stored procedure, the image is transformed into a table variable containing the original data.
Maybe there is a way this can be used with a temporary table.
I met the same problem and here is what I did for this from Paul's suggestion. The main part is here is to use NEWID() to avoid multiple users run the store procedures/scripts at the same time, the pain for global temporary table.
DECLARE #sql varchar(max) = '',
#tmp_global_table varchar(255) = '##global_tmp_' + CONVERT(varchar(36), NEWID())
SET #sql = #sql + 'select * into [' + #tmp_global_table + '] from YOURTABLE'
EXEC(#sql)
EXEC('SELECT * FROM [' + #tmp_global_table + ']')
Another method is to create a type and use PIPELINED to then pass back your object. This is limited to knowing the columns however. But it has the advantage of being able to do:
SELECT *
FROM TABLE(CAST(f$my_functions('8028767') AS my_tab_type))
This can be done in SQL Server 2014+ provided the stored procedure only returns one table. If anyone finds a way of doing this for multiple tables I'd love to know about it.
DECLARE #storedProcname NVARCHAR(MAX) = ''
SET #storedProcname = 'myStoredProc'
DECLARE #strSQL AS VARCHAR(MAX) = 'CREATE TABLE myTableName '
SELECT #strSQL = #strSQL+STUFF((
SELECT ',' +name+' ' + system_type_name
FROM sys.dm_exec_describe_first_result_set_for_object (OBJECT_ID(#storedProcname),0)
FOR XML PATH('')
),1,1,'(') + ')'
EXEC (#strSQL)
INSERT INTO myTableName
EXEC ('myStoredProc #param1=1, #param2=2')
SELECT * FROM myTableName
DROP TABLE myTableName
This pulls the definition of the returned table from system tables, and uses that to build the temp table for you. You can then populate it from the stored procedure as stated before.
There are also variants of this that work with Dynamic SQL too.
After searching around I found a way to create a temp table dynamically for any stored procedure without using OPENROWSET or OPENQUERY using a generic schema of Stored Procedure's result definition especially when you are not database Administrator.
Sql server has a buit-in proc sp_describe_first_result_set that can provide you with schema of any procedures resultset. I created a schema table from results of this procedure and manually set all the field to NULLABLE.
declare #procname varchar(100) = 'PROCEDURENAME' -- your procedure name
declare #param varchar(max) = '''2019-06-06''' -- your parameters
declare #execstr nvarchar(max) = N'exec ' + #procname
declare #qry nvarchar(max)
-- Schema table to store the result from sp_describe_first_result_set.

Developed and tested on Sql Server version - Microsoft SQL Server 2016 (RTM) - 13.0.1601.5(Build 17134:)
You can tweak the schema for your SQL server version that you are using (if needed).
It's a simple 2 step process:
- create a temporary table
- Insert into the temporary table.
Code to perform the same:
CREATE TABLE #tempTable (Column1 int, Column2 varchar(max));
INSERT INTO #tempTable
EXEC [app].[Sproc_name]
#param1 = 1,
#param2 =2;
If you know the parameters that are being passed and if you don't have access to make sp_configure, then edit the stored procedure with these parameters and the same can be stored in a ##global table.
A few years late to the question, but I needed something like this for some quick and dirty code generation. I believe as others have stated it is just easier to define the temp table up front, but this method should work for simple stored procedure queries or sql statments.
This will be a little convoluted, but it borrows from the contributors here as well as Paul White's solution from DBA Stack Exchange Get stored procedure result column-types. Again, to reiterate this approach & example is not designed for processes in a multi user environment. In this case the table definition is being set for a short time in a global temp table for reference by a code generation template process.
I haven't fully tested this so there may be caveats so you may want to go to the MSDN link in Paul White's answer. This applies to SQL 2012 and higher.
First use the stored procedure sp_describe_first_result_set which resembles Oracle's describe.
This will evaluate the first row of the first result set so if your stored procedure or statement returns multiple queries it will only describe the first result.
I created a stored proc to break down the tasks that returns a single field to select from to create the temp table definition.

The conundrum is that you need to use a global table, but you need to make it unique enough
so you can drop and create from it frequently without worrying about a collision.
In the example I used a Guid (FE264BF5_9C32_438F_8462_8A5DC8DEE49E) for the global variable replacing the hyphens with underscore
DECLARE #sql NVARCHAR(4000) = N'SELECT ##SERVERNAME as ServerName, GETDATE() AS Today;'
DECLARE #GlobalTempTable VARCHAR(100) = N'##FE264BF5_9C32_438F_8462_8A5DC8DEE49E_MyTempTable'
--#sql can be a stored procedure name like dbo.foo without parameters
DECLARE #TableDef NVARCHAR(MAX)
DROP TABLE IF EXISTS #MyTempTable
DROP TABLE IF EXISTS ##FE264BF5_9C32_438F_8462_8A5DC8DEE49E_MyTempTable
EXEC [dbo].[sp_GetTableDefinitionFromSqlBatch_DescribeFirstResultSet]
#sql, #GlobalTempTable, #TableDef OUTPUT
--Creates the global table ##FE264BF5_9C32_438F_8462_8A5DC8DEE49E_MyTempTable
EXEC sp_executesql #TableDef
--Now Call the stored procedure, SQL Statement with Params etc.
INSERT ##FE264BF5_9C32_438F_8462_8A5DC8DEE49E_MyTempTable
EXEC sp_executesql #sql
--Select the results into your undefined Temp Table from the Global Table
SELECT *
INTO #MyTempTable
FROM ##FE264BF5_9C32_438F_8462_8A5DC8DEE49E_MyTempTable
SELECT * FROM #MyTempTable
DROP TABLE IF EXISTS #MyTempTable
DROP TABLE IF EXISTS ##FE264BF5_9C32_438F_8462_8A5DC8DEE49E_MyTempTable

Well, you do have to create a temp table, but it doesn't have to have the right schema....I've created a stored procedure that modifies an existing temp table so that it has the required columns with the right data type and order (dropping all existing columns, adding new columns):
GO
create procedure #TempTableForSP(#tableId int, #procedureId int)
as
begin
declare #tableName varchar(max) = (select name
from tempdb.sys.tables
where object_id = #tableId
);
declare #tsql nvarchar(max);
declare #tempId nvarchar(max) = newid();
set #tsql = '
declare #drop nvarchar(max) = (select ''alter table tempdb.dbo.' + #tableName
+ ' drop column '' + quotename(c.name) + '';''+ char(10)
from tempdb.sys.columns c
where c.object_id = ' +
cast(#tableId as varchar(max)) + '
for xml path('''')
)
alter table tempdb.dbo.' + #tableName + ' add ' + QUOTENAME(#tempId) + ' int;
exec sp_executeSQL #drop;
declare #add nvarchar(max) = (
select ''alter table ' + #tableName
+ ' add '' + name
+ '' '' + system_type_name
+ case when d.is_nullable=1 then '' null '' else '''' end
+ char(10)
from sys.dm_exec_describe_first_result_set_for_object('
+ cast(#procedureId as varchar(max)) + ', 0) d
order by column_ordinal
for xml path(''''))
execute sp_executeSQL #add;
alter table ' + #tableName + ' drop column ' + quotename(#tempId) + ' ';
execute sp_executeSQL #tsql;
end
GO
create table #exampleTable (pk int);
declare #tableId int = object_Id('tempdb..#exampleTable')
declare #procedureId int = object_id('examplestoredProcedure')
exec #TempTableForSP #tableId, #procedureId;
insert into #exampleTable
exec examplestoredProcedure
Note this won't work if sys.dm_exec_describe_first_result_set_for_object can't determine the results of the stored procedure (for instance if it uses a temp table).
If you let dynamic SQL create a temp table, this table is owned by the Dynamic SQL connection, as opposed to the connection your stored procedure is called from.
DECLARE #COMMA_SEPARATED_KEYS varchar(MAX);
DROP TABLE IF EXISTS KV;
CREATE TABLE KV (id_person int, mykey varchar(30), myvalue int);

SET #ExecuteExpression = REPLACE(#ExecuteExpression, 'COMMA_SEPARATED_KEYS', #COMMA_SEPARATED_KEYS);
EXEC(#ExecuteExpression);
SELECT * FROM #Pivoted;
Msg 208, Level 16, State 0
Invalid object name '#Pivoted'.
This is because #Pivoted is owned by the Dynamic SQL connection. So the last instruction
SELECT * FROM #Pivoted
fails.
One way to not face this issue is to make sure all references to #Pivoted are made from inside the dynamic query itself:
DECLARE #COMMA_SEPARATED_KEYS varchar(MAX);
DROP TABLE IF EXISTS KV;
CREATE TABLE KV (id_person int, mykey varchar(30), myvalue int);
INSERT INTO KV VALUES

SET #ExecuteExpression = REPLACE(#ExecuteExpression, 'COMMA_SEPARATED_KEYS', #COMMA_SEPARATED_KEYS);
EXEC(#ExecuteExpression);
First, modify your stored procedure to save the end results in to a temp table. By doing this we are creating a table matching with the SP output fields. And then have a select statement to save that temp table to a any table name. Then execute the SP as explained in step 2
Step 1: modify your stored procedure to save the end results in to a temp table
[your stored procedure]
into #table_temp //this will insert the data to a temp table
from #table_temp
select * into SP_Output_Table_1 from #table_temp //this will save data to a actual table
Step 2: Execute the SP as below that will insert records to your table
Insert SP_Output_Table_1
EXE You_SP_Nane #Parameter1 = 52, #parameter2 =1
I have a table in SQL Server. The problem is how can I save the values of each column of a single row into separate variable in SQL Server 2012.
Something like:
SELECT Id, Name, School
FROM tblSchool
WHERE Id = 2
Then save the values of Id, Name, School into separate variables
If you want the values to be stored in separate variables (Your query returns only one matching row)
You can do like following
DECLARE #ID INT
DECLARE #Name VARCHAR(100)
DECLARE #School VARCHAR(100)
SELECT TOP 1 #ID=Id,#Name=Name,#School=School FROM tblSchool WHERE Id=2
SQL Server also supports table type variables, for your case you can create a table type as following.
CREATE TYPE [dbo].[MyVairable] AS TABLE(
Id INT NOT NULL,
Name VARCHAR(100) NULL,
School VARCHAR(100)
)
Declare the variable as following.
DECLARE #MyVariable [dbo].[MyVairable]
To select the rows into your variable.
INSERT INTO #MyVariable
SELECT Id,Name,School FROM tblSchool WHERE Id=2
Simply Declare the variables and stored it using:
DECLARE #ID INT, #Name VARCHAR(50), #School VARCHAR(50)
SELECT #ID=Id,#Name=Name,#School=School FROM tblSchool WHERE Id=2
DECLARE #ID INT
DECLARE #Name VARCHAR(50)
DECLARE #School VARCHAR(50)
SELECT #ID=Id,#Name=Name,#School=School
FROM tblSchool
WHERE Id=2
There are quite a few similar Questions, however i didn't quite find what i was looking for.
Since using dynamic SQL in a stored procedure can quickly get cumbersome, I want to pass a table name (Varchar) to a stored procedure, turn that Tablename into a Tablevariable and afterwards work with this Tablevariable for the rest of the procedure.
I can't figure out the code for this.
I'm working in SSMS on a SQL Server 2008R2. Currently my code looks similar to this. I lag the middle part to create the #Table Table Variable from the #TableName Varchar Variable
CREATE Procedure [dbo].StoredProc(#Tablename Varchar)
AS
Begin
Declare #Table Table (ColA Varchar, ColB Float)
Declare #result float
-- Something like Insert #Table Select * From #Tablename using Dynamic sql or sth. similar
Select #result = Select sum(ColB) From #Table
End
You can combine dynamic SQL and Temporary table storage the following way:
CREATE Procedure [dbo].StoredProc(#Tablename Varchar(100))
AS
Begin
create table #TempTbl (ColA Varchar(100), ColB Float);
Declare #result float
declare #dynSQL varchar(max);
select #dynSQL = 'insert into #TempTbl select
cast(val1 as varchar(100)) as ColA,
cast(val2 as float) as ColB from ' + COALESCE( #Tablename, 'NULL');
-- Tablename should contain schema name, 'dbo.' for example
exec( #dynSQL );
Select #result = sum(ColB) From #TempTbl
drop table #TempTbl;
return #Result;
End
you should set the statement yo need in a variable:
SET #sqlString='INSERT ' + #Table + ' SELECT * FROM ' + #Tablename
using Dynamic sql or sth. similar"
and then execute it:
EXEC sp_executesql #sqlString
USE AdventureWorks2012;
DECLARE #TableName NVARCHAR(MAX);
DECLARE #Copy TABLE
(
[ShiftID] [tinyint] NOT NULL,
[Name] [dbo].[Name] NOT NULL,
[StartTime] [time](7) NOT NULL,
[EndTime] [time](7) NOT NULL,
[ModifiedDate] [datetime] NOT NULL
);
SET #TableName = N'[HumanResources].[Shift]';
INSERT INTO #Copy
EXEC ('SELECT * FROM ' + #TableName);
SELECT * FROM #Copy;
I have a Dynamic Query.
create procedure SP_InsertGroup
(
#GroupID nvarchar(50)
,#GroupName nvarchar(max)
,#ParentId int
,#Username nvarchar(50)
)
Declare #Insertstring nvarchar(max);
set #Insertstring='INSERT INTO GroupDetails
(GroupID
,GroupName
,CreatedBy
,CreatedOn
,ParentID
,IsActive
)
values('+#GroupID+',
'''+#GroupName+''',
'''+#Username+''' ,
getdate(),
'+#ParentID+',
1,
)'
execute sp_executesql #query=#Insertstring
GroupDetails table accept nulls for all columns...but wen i exec the stored procedure in this way..
exec Sp_insertGroup '1',null,'1',null
I am unable to insert.why does this doesnt work in Dyanmic query please help me...
You don't need dynamic SQL
create procedure SP_InsertGroup
#GroupID nvarchar(50)
,#GroupName nvarchar(max)
,#ParentId int
,#Username nvarchar(50)
AS
INSERT GroupDetails
(GroupID
,GroupName
,CreatedBy
,CreatedOn
,ParentID
,IsActive
)
values(#GroupID, #GroupName, #Username, getdate(), #ParentID, 1)
GO
I'd also have defaults for CreatedOn and IsActive on the table
The reason it isn't working is that when you are building your dynamic SQL string and some of the elements are null, it makes the whole string null.
To fix it, you need to wrap any nullable elements with ISNULL(#param, 'null').
But don't do this, do what #gbn says.
How do I do a SELECT * INTO [temp table] FROM [stored procedure]? Not FROM [Table] and without defining [temp table]?
Select all data from BusinessLine into tmpBusLine works fine.
select *
into tmpBusLine
from BusinessLine
I am trying the same, but using a stored procedure that returns data, is not quite the same.
select *
into tmpBusLine
from
exec getBusinessLineHistory '16 Mar 2009'
Output message:
Msg 156, Level 15, State 1, Line 2
Incorrect syntax near the keyword
'exec'.
I have read several examples of creating a temporary table with the same structure as the output stored procedure, which works fine, but it would be nice to not supply any columns.
You can use OPENROWSET for this. Have a look. I've also included the sp_configure code to enable Ad Hoc Distributed Queries, in case it isn't already enabled.
CREATE PROC getBusinessLineHistory
AS
BEGIN
SELECT * FROM sys.databases
END
GO
sp_configure 'Show Advanced Options', 1
GO
RECONFIGURE
GO
sp_configure 'Ad Hoc Distributed Queries', 1
GO
RECONFIGURE
GO
SELECT * INTO #MyTempTable FROM OPENROWSET('SQLNCLI', 'Server=(local)\SQL2008;Trusted_Connection=yes;',
'EXEC getBusinessLineHistory')
SELECT * FROM #MyTempTable
If you want to do it without first declaring the temporary table, you could try creating a user-defined function rather than a stored procedure and make that user-defined function return a table. Alternatively, if you want to use the stored procedure, try something like this:
CREATE TABLE #tmpBus
(
COL1 INT,
COL2 INT
)
INSERT INTO #tmpBus
Exec SpGetRecords 'Params'
In SQL Server 2005 you can use INSERT INTO ... EXEC to insert the result of a stored procedure into a table. From MSDN's INSERT documentation (for SQL Server 2000, in fact):
--INSERT...EXECUTE procedure example
INSERT author_sales EXECUTE get_author_sales
This is an answer to a slightly modified version of your question. If you can abandon the use of a stored procedure for a user-defined function, you can use an inline table-valued user-defined function. This is essentially a stored procedure (will take parameters) that returns a table as a result set; and therefore will place nicely with an INTO statement.
Here's a good quick article on it and other user-defined functions. If you still have a driving need for a stored procedure, you can wrap the inline table-valued user-defined function with a stored procedure. The stored procedure just passes parameters when it calls select * from the inline table-valued user-defined function.
So for instance, you'd have an inline table-valued user-defined function to get a list of customers for a particular region:
CREATE FUNCTION CustomersByRegion
(
#RegionID int
)
RETURNS TABLE
AS
RETURN
SELECT *
FROM customers
WHERE RegionID = #RegionID
GO
You can then call this function to get what your results a such:
SELECT * FROM CustomersbyRegion(1)
Or to do a SELECT INTO:
SELECT * INTO CustList FROM CustomersbyRegion(1)
If you still need a stored procedure, then wrap the function as such:
CREATE PROCEDURE uspCustomersByRegion
(
#regionID int
)
AS
BEGIN
SELECT * FROM CustomersbyRegion(#regionID);
END
GO
I think this is the most 'hack-less' method to obtain the desired results. It uses the existing features as they were intended to be used without additional complications. By nesting the inline table-valued user-defined function in the stored procedure, you have access to the functionality in two ways. Plus! You have only one point of maintenance for the actual SQL code.
The use of OPENROWSET has been suggested, but this is not what the OPENROWSET function was intended to be used for (From Books Online):
Includes all connection information
that is required to access remote data
from an OLE DB data source. This
method is an alternative to accessing
tables in a linked server and is a
one-time, ad hoc method of connecting
and accessing remote data by using OLE
DB. For more frequent references to
OLE DB data sources, use linked
servers instead.
Using OPENROWSET will get the job done, but it will incur some additional overhead for opening up local connections and marshalling data. It also may not be an option in all cases since it requires an ad hoc query permission which poses a security risk and therefore may not be desired. Also, the OPENROWSET approach will preclude the use of stored procedures returning more than one result set. Wrapping multiple inline table-value user-defined functions in a single stored procedure can achieve this.
Select ##ServerName
EXEC sp_serveroption ##ServerName, 'DATA ACCESS', TRUE
SELECT *
INTO #tmpTable
FROM OPENQUERY(YOURSERVERNAME, 'EXEC db.schema.sproc 1')
Easiest Solution:
CREATE TABLE #temp (...);
INSERT INTO #temp
EXEC [sproc];
If you don't know the schema then you can do the following. Please
note that there are severe security risks in this method.
SELECT *
INTO #temp
FROM OPENROWSET('SQLNCLI',
'Server=localhost;Trusted_Connection=yes;',
'EXEC [db].[schema].[sproc]')
When the stored procedure returns a lot of columns and you do not want to manually "create" a temporary table to hold the result, I've found the easiest way is to go into the stored procedure and add an "into" clause on the last select statement and add 1=0 to the where clause.
Run the stored procedure once and go back and remove the SQL code you just added. Now, you'll have an empty table matching the stored procedure's result. You could either "script table as create" for a temporary table or simply insert directly into that table.
declare #temp table
(
name varchar(255),
field varchar(255),
filename varchar(255),
filegroup varchar(255),
size varchar(255),
maxsize varchar(255),
growth varchar(255),
usage varchar(255)
);
INSERT #temp Exec sp_helpfile;
select * from #temp;
If the results table of your stored proc is too complicated to type out the "create table" statement by hand, and you can't use OPENQUERY OR OPENROWSET, you can use sp_help to generate the list of columns and data types for you. Once you have the list of columns, it's just a matter of formatting it to suit your needs.
Step 1: Add "into #temp" to the output query (e.g. "select [...] into #temp from [...]").
The easiest way is to edit the output query in the proc directly. if you can't change the stored proc, you can copy the contents into a new query window and modify the query there.
Step 2: Run sp_help on the temp table. (e.g. "exec tempdb..sp_help #temp")
After creating the temp table, run sp_help on the temp table to get a list of the columns and data types including the size of varchar fields.
Step 3: Copy the data columns & types into a create table statement
I have an Excel sheet that I use to format the output of sp_help into a "create table" statement. You don't need anything that fancy, just copy and paste into your SQL editor. Use the column names, sizes, and types to construct a "Create table #x [...]" or "declare #x table [...]" statement which you can use to INSERT the results of the stored procedure.
Step 4: Insert into the newly created table
Now you'll have a query that's like the other solutions described in this thread.
DECLARE #t TABLE
(
--these columns were copied from sp_help
COL1 INT,
COL2 INT
)
INSERT INTO #t
Exec spMyProc
This technique can also be used to convert a temp table (#temp) to a table variable (#temp). While this may be more steps than just writing the create table statement yourself, it prevents manual error such as typos and data type mismatches in large processes. Debugging a typo can take more time than writing the query in the first place.
Does your stored procedure only retrieve the data or modify it too? If it's used only for retrieving, you can convert the stored procedure into a function and use the Common Table Expressions (CTEs) without having to declare it, as follows:
with temp as (
select * from dbo.fnFunctionName(10, 20)
)
select col1, col2 from temp
However, whatever needs to be retrieved from the CTE should be used in one statement only. You cannot do a with temp as ... and try to use it after a couple of lines of SQL. You can have multiple CTEs in one statement for more complex queries.
For example,
with temp1020 as (
select id from dbo.fnFunctionName(10, 20)
),
temp2030 as (
select id from dbo.fnFunctionName(20, 30)
)
select * from temp1020
where id not in (select id from temp2030)
If the OPENROWSET is causing you issues, there is another way from 2012 onwards; make use of sys.dm_exec_describe_first_result_set_for_object, as mentioned here: Retrieve column names and types of a stored procedure?
First, create this stored procedure to generate the SQL for the temporary table:
CREATE PROCEDURE dbo.usp_GetStoredProcTableDefinition(
#ProcedureName nvarchar(128),
#TableName nvarchar(128),
#SQL nvarchar(max) OUTPUT
)
AS
SET #SQL = 'CREATE TABLE ' + #tableName + ' ('
SELECT #SQL = #SQL + '['+name +'] '+ system_type_name +'' + ','
FROM sys.dm_exec_describe_first_result_set_for_object
(
OBJECT_ID(#ProcedureName),
NULL
);
--Remove trailing comma
SET #SQL = SUBSTRING(#SQL,0,LEN(#SQL))
SET #SQL = #SQL +')'
To use the procedure, call it in the following way:
DECLARE #SQL NVARCHAR(MAX)
exec dbo.usp_GetStoredProcTableDefinition
#ProcedureName='dbo.usp_YourProcedure',
#TableName='##YourGlobalTempTable',#SQL = #SQL OUTPUT
INSERT INTO ##YourGlobalTempTable
EXEC [dbo].usp_YourProcedure
select * from ##YourGlobalTempTable
Note that I'm using a global temporary table. That's because using EXEC to run the dynamic SQL creates its own session, so an ordinary temporary table would be out of scope to any subsequent code. If a global temporary table is a problem, you can use an ordinary temporary table, but any subsequent SQL would need to be dynamic, that is, also executed by the EXEC statement.
Quassnoi put me most of the way there, but one thing was missing:
****I needed to use parameters in the stored procedure.****
And OPENQUERY does not allow for this to happen:
So I found a way to work the system and also not have to make the table definition so rigid, and redefine it inside another stored procedure (and of course take the chance it may break)!
Yes, you can dynamically create the table definition returned from the stored procedure by
using the OPENQUERY statement with bogus varaiables (as long the NO RESULT SET returns the
same number of fields and in the same position as a dataset with good data).
Once the table is created, you can use exec stored procedure into the temporary table all day long.
And to note (as indicated above) you must enable data access,
EXEC sp_serveroption 'MYSERVERNAME', 'DATA ACCESS', TRUE
Code:
declare #locCompanyId varchar(8)
declare #locDateOne datetime
declare #locDateTwo datetime
set #locDateOne = '2/11/2010'
set #locDateTwo = getdate()
--Build temporary table (based on bogus variable values)
--because we just want the table definition and
--since openquery does not allow variable definitions...
--I am going to use bogus variables to get the table defintion.
select * into #tempCoAttendanceRpt20100211
FROM OPENQUERY(DBASESERVER,
'EXEC DATABASE.dbo.Proc_MyStoredProc 1,"2/1/2010","2/15/2010 3:00 pm"')
set #locCompanyId = '7753231'
insert into #tempCoAttendanceRpt20100211
EXEC DATABASE.dbo.Proc_MyStoredProc #locCompanyId,#locDateOne,#locDateTwo
set #locCompanyId = '9872231'
insert into #tempCoAttendanceRpt20100211
EXEC DATABASE.dbo.Proc_MyStoredProc #locCompanyId,#locDateOne,#locDateTwo
select * from #tempCoAttendanceRpt20100211
drop table #tempCoAttendanceRpt20100211
Thanks for the information which was provided originally...
Yes, finally I do not have to create all these bogus (strict) table defintions when using data from
another stored procedure or database, and yes you can use parameters too.

Update: this will not work with temporary tables so I had to resort to manually creating the temporary table.
Bummer notice: this will not work with temporary tables, http://www.sommarskog.se/share_data.html#OPENQUERY
Reference: The next thing is to define LOCALSERVER. It may look like a keyword in the example, but it is in fact only a name. This is how you do it:
sp_addlinkedserver #server = 'LOCALSERVER', #srvproduct = '',
#provider = 'SQLOLEDB', #datasrc = ##servername
To create a linked server, you must have the permission ALTER ANY SERVER, or be a member of any of the fixed server roles sysadmin or setupadmin.
OPENQUERY opens a new connection to SQL Server. This has some implications:
The procedure that you call with OPENQUERY cannot refer temporary tables created in the current connection.
The new connection has its own default database (defined with sp_addlinkedserver, default is master), so all object specification must include a database name.
If you have an open transaction and are holding locks when you call OPENQUERY, the called procedure can not access what you lock. That is, if you are not careful you will block yourself.
Connecting is not for free, so there is a performance penalty.
If you're lucky enough to have SQL 2012 or higher, you can use dm_exec_describe_first_result_set_for_object
I have just edited the sql provided by gotqn. Thanks gotqn.
This creates a global temp table with name same as procedure name. The temp table can later be used as required. Just don't forget to drop it before re-executing.
declare #procname nvarchar(255) = 'myProcedure',
#sql nvarchar(max)
set #sql = 'create table ##' + #procname + ' ('
begin
select #sql = #sql + '[' + r.name + '] ' + r.system_type_name + ','
from sys.procedures AS p
cross apply sys.dm_exec_describe_first_result_set_for_object(p.object_id, 0) AS r
where p.name = #procname
set #sql = substring(#sql,1,len(#sql)-1) + ')'
execute (#sql)
execute('insert ##' + #procname + ' exec ' + #procname)
end
This stored proc does the job:

It's a slight rework of this: Insert stored procedure results into table so that it actually works.
If you want it to work with a temporary table then you will need to use a ##GLOBAL table and drop it afterwards.
In order to insert the first record set of a stored procedure into a temporary table you need to know the following:
only the first row set of the stored procedure can be inserted into a temporary table
the stored procedure must not execute dynamic T-SQL statement (sp_executesql)
you need to define the structure of the temporary table first
The above may look as limitation, but IMHO it perfectly makes sense - if you are using sp_executesql you can once return two columns and once ten, and if you have multiple result sets, you cannot insert them into several tables as well - you can insert maximum in two table in one T-SQL statement (using OUTPUT clause and no triggers).
So, the issue is mainly how to define the temporary table structure before performing the EXEC ... INTO ... statement.
sys.dm_exec_describe_first_result_set_for_object
sys.dm_exec_describe_first_result_set
sp_describe_first_result_set
The first works with OBJECT_ID while the second and the third works with Ad-hoc queries as well. I prefer to use the DMV instead of the sp as you can use CROSS APPLY and build the temporary table definitions for multiple procedures at the same time.
SELECT p.name, r.*
FROM sys.procedures AS p
CROSS APPLY sys.dm_exec_describe_first_result_set_for_object(p.object_id, 0) AS r;
Also, pay attention to the system_type_name field as it can be very useful. It stores the column complete definition. For, example:
smalldatetime
nvarchar(max)
uniqueidentifier
nvarchar(1000)
real
smalldatetime
decimal(18,2)
and you can use it directly in most of the cases to create the table definition.
So, I think in most of the cases (if the stored procedure match certain criteria) you can easily build dynamic statements for solving such issues (create the temporary table, insert the stored procedure result in it, do what you need with the data).
Note, that the objects above fail to define the first result set data in some cases like when dynamic T-SQL statements are executed or temporary tables are used in the stored procedure.
I'm creating a table with the following schema and data.
Create a stored procedure.
Now I know what the result of my procedure is, so I am performing the following query.
CREATE TABLE [dbo].[tblTestingTree](
[Id] [int] IDENTITY(1,1) NOT NULL,
[ParentId] [int] NULL,
[IsLeft] [bit] NULL,
[IsRight] [bit] NULL,
CONSTRAINT [PK_tblTestingTree] PRIMARY KEY CLUSTERED
(
[Id] ASC
) WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
SET IDENTITY_INSERT [dbo].[tblTestingTree] ON
INSERT [dbo].[tblTestingTree] ([Id], [ParentId], [IsLeft], [IsRight]) VALUES (1, NULL, NULL, NULL)
INSERT [dbo].[tblTestingTree] ([Id], [ParentId], [IsLeft], [IsRight]) VALUES (2, 1, 1, NULL)
INSERT [dbo].[tblTestingTree] ([Id], [ParentId], [IsLeft], [IsRight]) VALUES (3, 1, NULL, 1)
INSERT [dbo].[tblTestingTree] ([Id], [ParentId], [IsLeft], [IsRight]) VALUES (4, 2, 1, NULL)
INSERT [dbo].[tblTestingTree] ([Id], [ParentId], [IsLeft], [IsRight]) VALUES (5, 2, NULL, 1)
INSERT [dbo].[tblTestingTree] ([Id], [ParentId], [IsLeft], [IsRight]) VALUES (6, 3, 1, NULL)
INSERT [dbo].[tblTestingTree] ([Id], [ParentId], [IsLeft], [IsRight]) VALUES (7, 3, NULL, 1)
INSERT [dbo].[tblTestingTree] ([Id], [ParentId], [IsLeft], [IsRight]) VALUES (8, 4, 1, NULL)
INSERT [dbo].[tblTestingTree] ([Id], [ParentId], [IsLeft], [IsRight]) VALUES (9, 4, NULL, 1)
INSERT [dbo].[tblTestingTree] ([Id], [ParentId], [IsLeft], [IsRight]) VALUES (10, 5, 1, NULL)
SET IDENTITY_INSERT [dbo].[tblTestingTree] OFF
VALUES (10, 5, 1, NULL)
SET IDENTITY_INSERT [dbo].[tblTestingTree] On
create procedure GetDate
as
begin
select Id,ParentId from tblTestingTree
end
create table tbltemp
(
id int,
ParentId int
)
insert into tbltemp
exec GetDate
select * from tbltemp;
If the query doesn't contain parameter, use OpenQuery else use OpenRowset.
Basic thing would be to create schema as per stored procedure and insert into that table. e.g.:
DECLARE #abc TABLE(
RequisitionTypeSourceTypeID INT
, RequisitionTypeID INT
, RequisitionSourcingTypeID INT
, AutoDistOverride INT
, AllowManagerToWithdrawDistributedReq INT
, ResumeRequired INT
, WarnSupplierOnDNRReqSubmission INT
, MSPApprovalReqd INT
, EnableMSPSupplierCounterOffer INT
, RequireVendorToAcceptOffer INT
, UseCertification INT
, UseCompetency INT
, RequireRequisitionTemplate INT
, CreatedByID INT
, CreatedDate DATE
, ModifiedByID INT
, ModifiedDate DATE
, UseCandidateScheduledHours INT
, WeekEndingDayOfWeekID INT
, AllowAutoEnroll INT
)
INSERT INTO #abc
EXEC [dbo].[usp_MySp] 726,3
SELECT * FROM #abc
Code
CREATE TABLE #T1
(
col1 INT NOT NULL,
col2 NCHAR(50) NOT NULL,
col3 TEXT NOT NULL,
col4 DATETIME NULL,
col5 NCHAR(50) NULL,
col6 CHAR(2) NULL,
col6 NCHAR(100) NULL,
col7 INT NULL,
col8 NCHAR(50) NULL,
col9 DATETIME NULL,
col10 DATETIME NULL
)
DECLARE #Para1 int
DECLARE #Para2 varchar(32)
DECLARE #Para3 varchar(100)
DECLARE #Para4 varchar(15)
DECLARE #Para5 varchar (12)
DECLARE #Para6 varchar(1)
DECLARE #Para7 varchar(1)
SET #Para1 = 1025
SET #Para2 = N'6as54fsd56f46sd4f65sd'
SET #Para3 = N'XXXX\UserName'
SET #Para4 = N'127.0.0.1'
SET #Para5 = N'XXXXXXX'
SET #Para6 = N'X'
SET #Para7 = N'X'
INSERT INTO #T1
(
col1,
col2,
col3,
col4,
col5,
col6,
col6,
col7,
col8,
col9,
col10,
)
EXEC [dbo].[usp_ProcedureName] #Para1, #Para2, #Para3, #Para4, #Para5, #Para6, #Para6
I hope this helps. Please qualify as appropriate.
I found Passing Arrays/DataTables into Stored Procedures which might give you another idea on how you might go solving your problem.
The link suggests to use an Image type parameter to pass into the stored procedure. Then in the stored procedure, the image is transformed into a table variable containing the original data.
Maybe there is a way this can be used with a temporary table.
I met the same problem and here is what I did for this from Paul's suggestion. The main part is here is to use NEWID() to avoid multiple users run the store procedures/scripts at the same time, the pain for global temporary table.
DECLARE #sql varchar(max) = '',
#tmp_global_table varchar(255) = '##global_tmp_' + CONVERT(varchar(36), NEWID())
SET #sql = #sql + 'select * into [' + #tmp_global_table + '] from YOURTABLE'
EXEC(#sql)
EXEC('SELECT * FROM [' + #tmp_global_table + ']')
Another method is to create a type and use PIPELINED to then pass back your object. This is limited to knowing the columns however. But it has the advantage of being able to do:
SELECT *
FROM TABLE(CAST(f$my_functions('8028767') AS my_tab_type))
This can be done in SQL Server 2014+ provided the stored procedure only returns one table. If anyone finds a way of doing this for multiple tables I'd love to know about it.
DECLARE #storedProcname NVARCHAR(MAX) = ''
SET #storedProcname = 'myStoredProc'
DECLARE #strSQL AS VARCHAR(MAX) = 'CREATE TABLE myTableName '
SELECT #strSQL = #strSQL+STUFF((
SELECT ',' +name+' ' + system_type_name
FROM sys.dm_exec_describe_first_result_set_for_object (OBJECT_ID(#storedProcname),0)
FOR XML PATH('')
),1,1,'(') + ')'
EXEC (#strSQL)
INSERT INTO myTableName
EXEC ('myStoredProc #param1=1, #param2=2')
SELECT * FROM myTableName
DROP TABLE myTableName
This pulls the definition of the returned table from system tables, and uses that to build the temp table for you. You can then populate it from the stored procedure as stated before.
There are also variants of this that work with Dynamic SQL too.
After searching around I found a way to create a temp table dynamically for any stored procedure without using OPENROWSET or OPENQUERY using a generic schema of Stored Procedure's result definition especially when you are not database Administrator.
Sql server has a buit-in proc sp_describe_first_result_set that can provide you with schema of any procedures resultset. I created a schema table from results of this procedure and manually set all the field to NULLABLE.
declare #procname varchar(100) = 'PROCEDURENAME' -- your procedure name
declare #param varchar(max) = '''2019-06-06''' -- your parameters
declare #execstr nvarchar(max) = N'exec ' + #procname
declare #qry nvarchar(max)
-- Schema table to store the result from sp_describe_first_result_set.

insert into #d
EXEC sp_describe_first_result_set #exestr, NULL, 0

stuff(

Developed and tested on Sql Server version - Microsoft SQL Server 2016 (RTM) - 13.0.1601.5(Build 17134:)
You can tweak the schema for your SQL server version that you are using (if needed).
It's a simple 2 step process:
- create a temporary table
- Insert into the temporary table.
Code to perform the same:
CREATE TABLE #tempTable (Column1 int, Column2 varchar(max));
INSERT INTO #tempTable
EXEC [app].[Sproc_name]
#param1 = 1,
#param2 =2;
If you know the parameters that are being passed and if you don't have access to make sp_configure, then edit the stored procedure with these parameters and the same can be stored in a ##global table.
A few years late to the question, but I needed something like this for some quick and dirty code generation. I believe as others have stated it is just easier to define the temp table up front, but this method should work for simple stored procedure queries or sql statments.
This will be a little convoluted, but it borrows from the contributors here as well as Paul White's solution from DBA Stack Exchange Get stored procedure result column-types. Again, to reiterate this approach & example is not designed for processes in a multi user environment. In this case the table definition is being set for a short time in a global temp table for reference by a code generation template process.
I haven't fully tested this so there may be caveats so you may want to go to the MSDN link in Paul White's answer. This applies to SQL 2012 and higher.
First use the stored procedure sp_describe_first_result_set which resembles Oracle's describe.
This will evaluate the first row of the first result set so if your stored procedure or statement returns multiple queries it will only describe the first result.
I created a stored proc to break down the tasks that returns a single field to select from to create the temp table definition.

The conundrum is that you need to use a global table, but you need to make it unique enough
so you can drop and create from it frequently without worrying about a collision.
In the example I used a Guid (FE264BF5_9C32_438F_8462_8A5DC8DEE49E) for the global variable replacing the hyphens with underscore
DECLARE #sql NVARCHAR(4000) = N'SELECT ##SERVERNAME as ServerName, GETDATE() AS Today;'
DECLARE #GlobalTempTable VARCHAR(100) = N'##FE264BF5_9C32_438F_8462_8A5DC8DEE49E_MyTempTable'
--#sql can be a stored procedure name like dbo.foo without parameters
DECLARE #TableDef NVARCHAR(MAX)
DROP TABLE IF EXISTS #MyTempTable
DROP TABLE IF EXISTS ##FE264BF5_9C32_438F_8462_8A5DC8DEE49E_MyTempTable
EXEC [dbo].[sp_GetTableDefinitionFromSqlBatch_DescribeFirstResultSet]
#sql, #GlobalTempTable, #TableDef OUTPUT
--Creates the global table ##FE264BF5_9C32_438F_8462_8A5DC8DEE49E_MyTempTable
EXEC sp_executesql #TableDef
--Now Call the stored procedure, SQL Statement with Params etc.
INSERT ##FE264BF5_9C32_438F_8462_8A5DC8DEE49E_MyTempTable
EXEC sp_executesql #sql
--Select the results into your undefined Temp Table from the Global Table
SELECT *
INTO #MyTempTable
FROM ##FE264BF5_9C32_438F_8462_8A5DC8DEE49E_MyTempTable
SELECT * FROM #MyTempTable
DROP TABLE IF EXISTS #MyTempTable
DROP TABLE IF EXISTS ##FE264BF5_9C32_438F_8462_8A5DC8DEE49E_MyTempTable

Well, you do have to create a temp table, but it doesn't have to have the right schema....I've created a stored procedure that modifies an existing temp table so that it has the required columns with the right data type and order (dropping all existing columns, adding new columns):
GO
create procedure #TempTableForSP(#tableId int, #procedureId int)
as
begin
declare #tableName varchar(max) = (select name
from tempdb.sys.tables
where object_id = #tableId
);
declare #tsql nvarchar(max);
declare #tempId nvarchar(max) = newid();
set #tsql = '
declare #drop nvarchar(max) = (select ''alter table tempdb.dbo.' + #tableName
+ ' drop column '' + quotename(c.name) + '';''+ char(10)
from tempdb.sys.columns c
where c.object_id = ' +
cast(#tableId as varchar(max)) + '
for xml path('''')
)
alter table tempdb.dbo.' + #tableName + ' add ' + QUOTENAME(#tempId) + ' int;
exec sp_executeSQL #drop;
declare #add nvarchar(max) = (
select ''alter table ' + #tableName
+ ' add '' + name
+ '' '' + system_type_name
+ case when d.is_nullable=1 then '' null '' else '''' end
+ char(10)
from sys.dm_exec_describe_first_result_set_for_object('
+ cast(#procedureId as varchar(max)) + ', 0) d
order by column_ordinal
for xml path(''''))
execute sp_executeSQL #add;
alter table ' + #tableName + ' drop column ' + quotename(#tempId) + ' ';
execute sp_executeSQL #tsql;
end
GO
create table #exampleTable (pk int);
declare #tableId int = object_Id('tempdb..#exampleTable')
declare #procedureId int = object_id('examplestoredProcedure')
exec #TempTableForSP #tableId, #procedureId;
insert into #exampleTable
exec examplestoredProcedure
Note this won't work if sys.dm_exec_describe_first_result_set_for_object can't determine the results of the stored procedure (for instance if it uses a temp table).
If you let dynamic SQL create a temp table, this table is owned by the Dynamic SQL connection, as opposed to the connection your stored procedure is called from.

EXEC(#ExecuteExpression);
SELECT * FROM #Pivoted;
Msg 208, Level 16, State 0
Invalid object name '#Pivoted'.
This is because #Pivoted is owned by the Dynamic SQL connection. So the last instruction
SELECT * FROM #Pivoted
fails.
One way to not face this issue is to make sure all references to #Pivoted are made from inside the dynamic query itself:

First, modify your stored procedure to save the end results in to a temp table. By doing this we are creating a table matching with the SP output fields. And then have a select statement to save that temp table to a any table name. Then execute the SP as explained in step 2
Step 1: modify your stored procedure to save the end results in to a temp table
[your stored procedure]
into #table_temp //this will insert the data to a temp table
from #table_temp
select * into SP_Output_Table_1 from #table_temp //this will save data to a actual table
Step 2: Execute the SP as below that will insert records to your table
Insert SP_Output_Table_1
