I am trying to create a stored procedure that does manipulation of parameter passed in before inserting it into my table. One of the columns in my table is called DATE_CHANGED and basically what I gg to do here is to change a passed date parameter like December 1st 2017 to 20171201. This is an int value.
I wrote a stored procedure like this:
CREATE PROCEDURE date_generate
#startDate DATE
AS
BEGIN
DECLARE #DATE_KEY INT
#DATE_KEY = CONVERT(INT, FORMAT(#startDate, 'YYYYMMDD')
INSERT INTO table date_key = #DATE_KEY
END
However I get an error
Incorrect syntax near '#DATE_KEY
Are local variable declared only used for SQL query statement like
select *
from table
where date_key = #DATE_Key?
There is more than one error.
Use SET to assign values to a variable.
Have a look at INSERT statement too.
CREATE PROCEDURE date_generate
#startDate date
AS
BEGIN
DECLARE #DATE_KEY int;
SET #DATE_KEY = CONVERT(int, format(#startDate, 'YYYYMMDD'));
INSERT INTO DATE_CHANGED (date_key)
VALUES (#DATE_KEY);
END
This seems really strange. You don't even need a local variable. Based on your code, you could write:
create procedure date_generate (
#startDate date
) as
begin
insert into table (date_key)
values ( convert(int, format(#startDate, 'YYYYMMDD')) );
end; -- date_generate
Or, I might write:
create procedure date_generate (
#startDate date
) as
begin
insert into table (date_key)
values ( year(#startDate) * 10000 + month(#startDate) * 100 + day(#startDate) );
end;
Why you would have a table with a single date on each row doesn't really make sense to me. Why you would be storing that "date" as an integer also doesn't make sense.
As far as I've understood, your stored procedure accepts a DATE as a parameter, but you need to do an INSERT with an INT.
You can easily convert a DATE to a VARCHAR and then to a INT, this way:
DECLARE #DateASInt INT = CAST(CONVERT(VARCHAR(8), #startDate, 112) AS INT);
So, your stored procedure will be like this:
CREATE PROCEDURE date_generate
#startDate date
AS
BEGIN
INSERT INTO date_key
VALUES (CAST(CONVERT(VARCHAR(8), #startDate, 112) AS INT));
END
I have a stored procedure that takes in two parameters. I can execute it successfully in Server Management Studio. It shows me the results which are as I expect. However it also returns a Return Value.
It has added this line,
SELECT 'Return Value' = #return_value
I would like the stored procedure to return the table it shows me in the results not the return value as I am calling this stored procedure from MATLAB and all it returns is true or false.
Do I need to specify in my stored procedure what it should return? If so how do I specify a table of 4 columns (varchar(10), float, float, float)?
A procedure can't return a table as such. However you can select from a table in a procedure and direct it into a table (or table variable) like this:
create procedure p_x
as
begin
declare #t table(col1 varchar(10), col2 float, col3 float, col4 float)
insert #t values('a', 1,1,1)
insert #t values('b', 2,2,2)
select * from #t
end
go
declare #t table(col1 varchar(10), col2 float, col3 float, col4 float)
insert #t
exec p_x
select * from #t
I do this frequently using Table Types to ensure more consistency and simplify code. You can't technically return "a table", but you can return a result set and using INSERT INTO .. EXEC ... syntax, you can clearly call a PROC and store the results into a table type. In the following example I'm actually passing a table into a PROC along with another param I need to add logic, then I'm effectively "returning a table" and can then work with that as a table variable.
/****** Check if my table type and/or proc exists and drop them ******/
IF EXISTS (SELECT * FROM sys.objects WHERE type = 'P' AND name = 'returnTableTypeData')
DROP PROCEDURE returnTableTypeData
GO
IF EXISTS (SELECT * FROM sys.types WHERE is_table_type = 1 AND name = 'myTableType')
DROP TYPE myTableType
GO
/****** Create the type that I'll pass into the proc and return from it ******/
CREATE TYPE [dbo].[myTableType] AS TABLE(
[someInt] [int] NULL,
[somenVarChar] [nvarchar](100) NULL
)
GO
CREATE PROC returnTableTypeData
#someInputInt INT,
#myInputTable myTableType READONLY --Must be readonly because
AS
BEGIN
--Return the subset of data consistent with the type
SELECT
*
FROM
#myInputTable
WHERE
someInt < #someInputInt
END
GO
DECLARE #myInputTableOrig myTableType
DECLARE #myUpdatedTable myTableType
INSERT INTO #myInputTableOrig ( someInt,somenVarChar )
VALUES ( 0, N'Value 0' ), ( 1, N'Value 1' ), ( 2, N'Value 2' )
INSERT INTO #myUpdatedTable EXEC returnTableTypeData #someInputInt=1, #myInputTable=#myInputTableOrig
SELECT * FROM #myUpdatedTable
DROP PROCEDURE returnTableTypeData
GO
DROP TYPE myTableType
GO
Consider creating a function which can return a table and be used in a query.
https://msdn.microsoft.com/en-us/library/ms186755.aspx
The main difference between a function and a procedure is that a function makes no changes to any table. It only returns a value.
In this example I'm creating a query to give me the counts of all the columns in a given table which aren't null or empty.
There are probably many ways to clean this up. But it illustrates a function well.
USE Northwind
CREATE FUNCTION usp_listFields(#schema VARCHAR(50), #table VARCHAR(50))
RETURNS #query TABLE (
FieldName VARCHAR(255)
)
BEGIN
INSERT #query
SELECT
'SELECT ''' + #table+'~'+RTRIM(COLUMN_NAME)+'~''+CONVERT(VARCHAR, COUNT(*)) '+
'FROM '+#schema+'.'+#table+' '+
' WHERE isnull("'+RTRIM(COLUMN_NAME)+'",'''')<>'''' UNION'
FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = #table and TABLE_SCHEMA = #schema
RETURN
END
Then executing the function with
SELECT * FROM usp_listFields('Employees')
produces a number of rows like:
SELECT 'Employees~EmployeeID~'+CONVERT(VARCHAR, COUNT(*)) FROM dbo.Employees WHERE isnull("EmployeeID",'')<>'' UNION
SELECT 'Employees~LastName~'+CONVERT(VARCHAR, COUNT(*)) FROM dbo.Employees WHERE isnull("LastName",'')<>'' UNION
SELECT 'Employees~FirstName~'+CONVERT(VARCHAR, COUNT(*)) FROM dbo.Employees WHERE isnull("FirstName",'')<>'' UNION
You can use an out parameter instead of the return value if you want both a result set and a return value
CREATE PROCEDURE proc_name
#param int out
AS
BEGIN
SET #param = value
SELECT ... FROM [Table] WHERE Condition
END
GO
I had a similar situation and solved by using a temp table inside the procedure, with the same fields being returned by the original Stored Procedure:
CREATE PROCEDURE mynewstoredprocedure
AS
BEGIN
INSERT INTO temptable (field1, field2)
EXEC mystoredprocedure #param1, #param2
select field1, field2 from temptable
-- (mystoredprocedure returns field1, field2)
END
The Status Value being returned by a Stored Procedure can only be an INT datatype. You cannot return other datatypes in the RETURN statement.
From Lesson 2: Designing Stored Procedures:
Every stored procedure can return an integer value known as the
execution status value or return code.
If you still want a table returned from the SP, you'll either have to work the record set returned from a SELECT within the SP or tie into an OUTPUT variable that passes an XML datatype.

Though this question is very old but as a new in Software Development I can't stop my self to share what I have learnt :D
Creation of Stored Procedure:
CREATE PROC usp_ValidateUSer
(
#UserName nVARCHAR(50),
#Password nVARCHAR(50)
)
AS
BEGIN
IF EXISTS(SELECT '#' FROM Users WHERE Username=#UserName AND Password=#Password)
BEGIN
SELECT u.UserId, u.Username, r.UserRole
FROM Users u
INNER JOIN UserRoles r
ON u.UserRoleId=r.UserRoleId
END
END
Execution of Stored Procedure:
(If you want to test the execution of Stored Procedure in SQL)
EXEC usp_ValidateUSer #UserName='admin', #Password='admin'
The Output:
create procedure PSaleCForms
as
begin
declare
#b varchar(9),
#c nvarchar(500),
#q nvarchar(max)
declare #T table(FY nvarchar(9),Qtr int,title nvarchar (max),invoicenumber nvarchar(max),invoicedate datetime,sp decimal 18,2),grandtotal decimal(18,2))
declare #data cursor
set #data= Cursor
forward_only static
for
select x.DBTitle,y.CurrentFinancialYear from [Accounts Manager].dbo.DBManager x inner join [Accounts Manager].dbo.Accounts y on y.DBID=x.DBID where x.cfy=1
open #data
fetch next from #data
into #c,#b
while ##FETCH_STATUS=0
begin
set #q=N'Select '''+#b+''' [fy], case cast(month(i.invoicedate)/3.1 as int) when 0 then 4 else cast(month(i.invoicedate)/3.1 as int) end [Qtr], l.title,i.invoicenumber,i.invoicedate,i.sp,i.grandtotal from ['+#c+'].dbo.invoicemain i inner join ['+#c+'].dbo.ledgermain l on l.ledgerid=i.ledgerid where (sp=0 or stocktype=''x'') and invoicetype=''DS'''
insert into #T exec [master].dbo.sp_executesql #q
fetch next from #data
into #c,#b
end
close #data
deallocate #data
select * from #T
return
end
Here's an example of a SP that both returns a table and a return value. I don't know if you need the return the "Return Value" and I have no idea about MATLAB and what it requires.
CREATE PROCEDURE test
AS
BEGIN
SELECT * FROM sys.databases
RETURN 27
END
--Use this to test
DECLARE #returnval int
EXEC #returnval = test
SELECT #returnval
I'd like to pass a table as a parameter into a scaler UDF.
I'd also prefer to restrict the parameter to tables with only one column. (optional)
Is this possible?
EDIT
I don't want to pass a table name, I'd like to pass the table of data (as a reference I presume)
EDIT
I would want my Scaler UDF to basically take a table of values and return a CSV list of the rows.
IE
col1
"My First Value"
"My Second Value"
...
"My nth Value"
would return
"My First Value, My Second Value,... My nth Value"
I'd like to do some filtering on the table though, IE ensuring that there are no nulls and to ensure there are no duplicates. I was expecting something along the lines of:
SELECT dbo.MyFunction(SELECT DISTINCT myDate FROM myTable WHERE myDate IS NOT NULL)
You can, however no any table. From documentation:
For Transact-SQL functions, all data
types, including CLR user-defined
types and user-defined table types,
are allowed except the timestamp data
type.
You can use user-defined table types.
Example of user-defined table type:
CREATE TYPE TableType
AS TABLE (LocationName VARCHAR(50))
GO
DECLARE #myTable TableType
INSERT INTO #myTable(LocationName) VALUES('aaa')
SELECT * FROM #myTable
So what you can do is to define your table type, for example TableType and define the function which takes the parameter of this type. An example function:
CREATE FUNCTION Example( #TableName TableType READONLY)
RETURNS VARCHAR(50)
AS
BEGIN
DECLARE #name VARCHAR(50)
SELECT TOP 1 #name = LocationName FROM #TableName
RETURN #name
END
The parameter has to be READONLY. And example usage:
DECLARE #myTable TableType
INSERT INTO #myTable(LocationName) VALUES('aaa')
SELECT * FROM #myTable
SELECT dbo.Example(#myTable)
Depending on what you want achieve you can modify this code.
EDIT:
If you have a data in a table you may create a variable:
DECLARE #myTable TableType
And take data from your table to the variable
INSERT INTO #myTable(field_name)
SELECT field_name_2 FROM my_other_table
Unfortunately, there is no simple way in SQL Server 2005. Lukasz' answer is correct for SQL Server 2008 though and the feature is long overdue
Any solution would involve temp tables, or passing in xml/CSV and parsing in the UDF. Example: change to xml, parse in udf
DECLARE #psuedotable xml
SELECT
#psuedotable = ...
FROM
...
FOR XML ...
SELECT ... dbo.MyUDF (#psuedotable)
What do you want to do in the bigger picture though? There may be another way to do this...
Edit: Why not pass in the query as a string and use a stored proc with output parameter
Note: this is an untested bit of code, and you'd need to think about SQL injection etc. However, it also satisfies your "one column" requirement and should help you along
CREATE PROC dbo.ToCSV (
#MyQuery varchar(2000),
#CSVOut varchar(max)
)
AS
SET NOCOUNT ON
CREATE TABLE #foo (bar varchar(max))
INSERT #foo
EXEC (#MyQuery)
SELECT
#CSVOut = SUBSTRING(buzz, 2, 2000000000)
FROM
(
SELECT
bar -- maybe CAST(bar AS varchar(max))??
FROM
#foo
FOR XML PATH (',')
) fizz(buzz)
GO
Step 1: Create a Type as Table with name TableType that will accept a table having one varchar column
create type TableType
as table ([value] varchar(100) null)
Step 2: Create a function that will accept above declared TableType as Table-Valued Parameter and String Value as Separator
create function dbo.fn_get_string_with_delimeter (#table TableType readonly,#Separator varchar(5))
returns varchar(500)
As
begin
declare #return varchar(500)
set #return = stuff((select #Separator + value from #table for xml path('')),1,1,'')
return #return
end
Step 3: Pass table with one varchar column to the user-defined type TableType and ',' as separator in the function
select dbo.fn_get_string_with_delimeter(#tab, ',')
Cutting to the bottom line, you want a query like SELECT x FROM y to be passed into a function that returns the values as a comma separated string.
As has already been explained you can do this by creating a table type and passing a UDT into the function, but this needs a multi-line statement.
You can pass XML around without declaring a typed table, but this seems to need a xml variable which is still a multi-line statement i.e.
DECLARE #MyXML XML = (SELECT x FROM y FOR XML RAW);
SELECT Dbo.CreateCSV(#MyXml);
The "FOR XML RAW" makes the SQL give you it's result set as some xml.
But you can bypass the variable using Cast(... AS XML). Then it's just a matter of some XQuery and a little concatenation trick:
CREATE FUNCTION CreateCSV (#MyXML XML)
RETURNS VARCHAR(MAX)
BEGIN
DECLARE #listStr VARCHAR(MAX);
SELECT
#listStr =
COALESCE(#listStr+',' ,'') +
c.value('#Value[1]','nvarchar(max)')
FROM #myxml.nodes('/row') as T(c)
RETURN #listStr
END
GO
-- And you call it like this:
SELECT Dbo.CreateCSV(CAST(( SELECT x FROM y FOR XML RAW) AS XML));
-- Or a working example
SELECT Dbo.CreateCSV(CAST((
SELECT DISTINCT number AS Value
FROM master..spt_values
WHERE type = 'P'
AND number <= 20
FOR XML RAW) AS XML));
As long as you use FOR XML RAW all you need do is alias the column you want as Value, as this is hard coded in the function.
PASSING TABLE AS PARAMETER IN STORED PROCEDURE

(
Id int,
Name nvarchar(50),
Gender nvarchar(10),
Salary int
)
Step 2:
CREATE TYPE EmpInsertType AS TABLE
(
Id int,

Salary int
)
Step 3:
/* Must add READONLY keyword at end of the variable */
CREATE PROC PRC_EmpInsertType
#EmployeeInsertType EmpInsertType READONLY
AS
BEGIN
INSERT INTO [DBO].T_EMPLOYEES_DETAILS
SELECT * FROM #EmployeeInsertType

INSERT INTO #EmployeeInsertType VALUES(2,'Praveen','Male',60000)
INSERT INTO #EmployeeInsertType VALUES(3,'Chitra','Female',45000)
INSERT INTO #EmployeeInsertType VALUES(4,'Mathy','Female',6600)
INSERT INTO #EmployeeInsertType VALUES(5,'Sam','Male',50000)

I've been dealing with a very similar problem and have been able to achieve what I was looking for, even though I'm using SQL Server 2000. I know it is an old question, but think its valid to post here the solution since there should be others like me that use old versions and still need help.
Here's the trick: SQL Server won't accept passing a table to a UDF, nor you can pass a T-SQL query so the function creates a temp table or even calls a stored procedure to do that. So, instead, I've created a reserved table, which I called xtList. This will hold the list of values (1 column, as needed) to work with.
CREATE TABLE [dbo].[xtList](
[List] [varchar](1000) NULL
) ON [PRIMARY]
Then, a stored procedure to populate the list. This is not strictly necessary, but I think is very usefull and best practice.

-- =============================================
CREATE PROCEDURE [dbo].[xpCreateList]
#ListQuery varchar(2000)
AS
BEGIN
SET NOCOUNT ON;
DELETE FROM xtList
INSERT INTO xtList
EXEC(#ListQuery)
END
Now, just deal with the list in any way you want, using the xtList. You can use in a procedure (for executing several T-SQL commands), scalar functions (for retrieving several strings) or multi-statement table-valued functions (retrieves the strings but like it was inside a table, 1 string per row). For any of that, you'll need cursors:
DECLARE #Item varchar(100)
DECLARE cList CURSOR DYNAMIC
FOR (SELECT * FROM xtList WHERE List is not NULL)
OPEN cList
FETCH FIRST FROM cList INTO #Item
WHILE ##FETCH_STATUS = 0 BEGIN
<< desired action with values >>
FETCH NEXT FROM cList INTO #Item
END
CLOSE cList
DEALLOCATE cList
The desired action would be as follows, depending on which type of object created:
