I want to know if it is possible to insert to a table from a specific column of result from a stored procedure?
Something like:
declare #temp as table(
id int
)
insert #temp
exec getlistofStudents --returns multiple columns
this is an example only, Thanks for the help..
You can take a 2 step approach. First INSERT INTO a #TempTable, then populate the #TempVariable with another INSERT INTO, selecting the single column.
DECLARE #temp AS TABLE
(
ID int
);
CREATE TABLE #tempTable1
(
Column1 int,
Column2 int
);
INSERT INTO #tempTable1
Exec getlistofStudents
INSERT INTO #temp
SELECT Column1 FROM #tempTable1

Having the following procedure:
CREATE PROCEDURE [dbo].[Gest_Doc_SampleProc]
#Nome nvarchar(255),
#Descritivo nvarchar(255),
#SampleTable AS dbo.IDList READONLY
AS
DECLARE #foo int;
SELECT #foo=a.bar FROM TableA a WHERE a.Nome=#Nome
IF NOT EXISTS (SELECT a.bar FROM TableA a WHERE a.Nome=#Nome)
BEGIN
INSERT INTO TableA VALUES (#Nome,#Descritivo)
INSERT INTO TableB VALUES (scope_identity(),#SampleTable)
END
I am trying, as shown, inserting into TableB all the values of SampleTable, together with the scope_identity.
SampleTable is as:
CREATE TYPE dbo.SampleTable
AS TABLE
(
ID INT
);
GO
How can I correctly achieve this?
The right way to do this type of work is the OUTPUT clause. Although technically not needed for a single row insert, you might as well learn how to do it correctly. And even what looks like a single row insert can have an insert trigger that does unexpected things.
PROCEDURE [dbo].[Gest_Doc_SampleProc] (
#Nome nvarchar(255),
#Descritivo nvarchar(255),
#SampleTable AS dbo.IDList
) READONLY AS
BEGIN
DECLARE #ids TABLE (id int);
DECLARE #foo int;
SELECT #foo = a.bar
FROM TableA a
WHERE a.Nome = #Nome;
IF NOT EXISTS (SELECT 1 FROM TableA a WHERE a.Nome = #Nome)
BEGIN
INSERT INTO TableA (Nome, Descritive)
OUTPUT Inserted.id -- or whatever the id is called
INTO #ids;
VALUES (#Nome,#Descritivo)
INSERT INTO TableB (id, sampletable)
SELECT id, #SampleTable
FROM #ids;
END;
END; -- Gest_Doc_SampleProc
In addition to using OUTPUT, this code also adds column lists to the INSERTs. That is another best practice.
I have a Database and i want to execute few queries on it, and the results of the queries i.e. message, has to be comapared in my code if it is expected or not.
Please let me know how to capture the output of the SQL queries in any variable that can be used later in code for comparision.
Try the following Method :
Create a Table with the Same structure as of your Procedure output
Insert the Result of the SP Execution to the Table
Compare your Query result with the Table
Like this
CREATE PROCEDURE dbo.uSp_Temp
AS
SELECT
GETDATE() "MyDate"
DECLARE #T TABLE
(
MyDate DATE
)
INSERT INTO #T
EXEC uSp_Temp
SELECT
*
FROM #T
You can use Temp tables or temp variable to save the result set of a query.
Below is the sample for temp table
create table #temp (id int)
insert into #temp
select 1 as id
select * from #temp
Below is sample for Temp variable
declare #temp table (id int)
insert into #temp
select 1 as id
select * from #temp
For table1 Inserted 3 records
It should get those three identities and it should insert 3 records in table3 (but it’s not happening- it inserts 3 records with same identity ie.last scope identity)
create table table1(ID INT identity(1,1),Name varchar(50))
insert into table1 values('Ram'),('Sitha'),('Laxman')
create table table1(ID INT identity(1,1),Name varchar(50))
create table table3(ID INT ,Name varchar(50))
insert into table2(Name)
select Name from table1
declare #id int;
set #id= (select scope_Identity())
begin
insert into table3(ID,Name)
select #id,Name from table2
end
select * from table2
select * from table3
How can get all identities to insert do I need to write a loop (or) do I need to Create a trigger.
Please give me a solution I am strugguling from past 4 hours.
Thanks in anvance
Use the OUTPUT clause to handle multi-row inserts:
INSERT INTO dbo.table2(Name)
OUTPUT inserted.ID, inserted.Name INTO table3
SELECT Name FROM dbo.table1;
You can use the OUTPUT clause to get the identity from any number of inserts.
create table table1(ID INT identity(1,1),Name varchar(50))
DECLARE #T1 Table (ID int, name varchar(50))
insert into table1
OUTPUT inserted.ID, Inserted.Name INTO #T1
values('Ram'),('Sitha'),('Laxman')
DECLARE #IdentityId INT,#Count INT=1
DECLARE #temp AS TABLE (Id INT IDENTITY ,Name NVARCHAR(100))
INSERT INTO #temp(Name)
SELECT Name FROM table1
WHILE #Count <=(SELECT COUNT(SId) FROM #temp)
BEGIN
INSERT INTO table2(Name)
SELECT Name FROM #temp
WHERE Id=#Count
SET #IdentityId = SCOPE_IDENTITY()
INSERT INTO tabel3(#IdentityId,Name)
SELECT 3, #IdentityId,1,GETDATE()
SET #Count=#Count+1
END
I have a stored proc where I am deleting a row from a table.
Is there a way to return the ID of the row deleted? I know there's a way to do it with inserting (SCOPE_IDENTITY()), but it doesn't seem to work for deletions.
The code:
BEGIN
declare #returnVal int
DELETE FROM table WHERE num = 1;
set #returnVal = /*HOW TO GET ID OF ROW DELETED?*/
END;
Yes you can. From here:-
CREATE TABLE TestTable (ID INT, TEXTVal VARCHAR(100))
----Creating temp table to store ovalues of OUTPUT clause
DECLARE #TmpTable TABLE (ID INT, TEXTVal VARCHAR(100))
----Insert values in real table
INSERT TestTable (ID, TEXTVal)
VALUES (1,'FirstVal')
INSERT TestTable (ID, TEXTVal)
VALUES (2,'SecondVal')
----Update the table and insert values in temp table using Output clause
DELETE
FROM TestTable
OUTPUT Deleted.ID, Deleted.TEXTVal INTO #TmpTable
WHERE ID IN (1,2)
----Check the values in the temp table and real table
----The values in both the tables will be same
SELECT * FROM #TmpTable
SELECT * FROM TestTable
----Clean up time
DROP TABLE TestTable
GO
You will have to run 2 commands: SELECT to retrieve ID and DELETE to actually perform deleteion.
BEGIN
declare #returnVal int
SELECT #returnVal = ID FROM table WHERE num = 1;
DELETE FROM table WHERE num = 1;
END;
Unless you delete based on ID - in that case you already know it.
Just insert an OUTPUT clause between the DELETE FROM and WHERE:
DECLARE #returnVal TABLE ([id] [int] NOT NULL)
DELETE FROM table
OUTPUT deleted.[id] INTO #returnVal
WHERE num = 1;
/* #returnVal contains the [id] values of all deleted rows. */
In a DELETE statement, you can access the data of deleted rows by the auto-created deleted table alias.
I have a stored procedure that returns 6 columns. But I want to take only 2 columns and insert them into my table variable.
DECLARE #CategoryTable TABLE(
CategoryId Int NOT NULL,
Name nvarchar(255) NOT NULL
)
INSERT INTO #CategoryTable EXEC [GetAllTenantCategories] #TenantId
When I run this
Column name or number of supplied values does not match table
definition
How to insert only specified columns from a stored procedure?
I do not want to use SELECT INTO as it is not supported by SQL Azure
Tried below and got Invalid object name '#Temp'
DECLARE #CategoryTable TABLE(
CategoryId Int NOT NULL,
Name nvarchar(255) NOT NULL
)
INSERT INTO #Temp EXEC [GetAllTenantCategories] 1
INSERT INTO #CategoryTable (CategoryId, Name)
SELECT CategoryId, Name from #Temp
DROP TABLE #Temp
You can create a temp table first and the INSERT the required columns in your table variable.
CREATE TABLE #temp
(
your columns and datatype
)
INSERT INTO #temp
EXEC [GetAllTenantCategories] #TenantId
Then you can,
DECLARE #CategoryTable TABLE(
CategoryId Int NOT NULL,
Name nvarchar(255) NOT NULL
)
INSERT INTO #CategoryTable (CategoryId, Name)
select CategoryId, Name from #temp
Also drop the #temp table,
DROP TABLE #temp
Refer the points taken from https://www.simple-talk.com/sql/performance/execution-plan-basics/
When the Estimated Plan is Invalid
In some instances, the estimated plan won't work at all. For example, try generating an estimated plan for this simple bit of code:
CREATE TABLE TempTable
(
Id INT IDENTITY (1 , 1 )
,Dsc NVARCHAR (50 )
);
INSERT INTO TempTable ( Dsc )
SELECT [Name]
FROM [Sales] .[Store] ;
SELECT *
FROM TempTable ;
DROP TABLE TempTable ;
You will get this error:
Invalid object name 'TempTable'.
The optimizer, which is what is used to generate Estimated Execution plans, doesn't execute T-SQL.
It does run the statements through the algebrizer , the process outlined earlier that is responsible for verifying the names of database objects. Since the query has not yet been executed, the temporary table does not yet exist. This is the cause of the error.
Running this same bit of code through the Actual execution plan will work perfectly fine.
Hope you got why your temp table approach not worked :) Because you might tried as T-SQL
We can use OPENQUERY
SELECT EmployeeID,CurrentSalary INTO #tempEmp
FROM OPENQUERY(LOCALSERVER,'Exec TestDB.dbo.spEmployee')
