how to call a stored procedure in SSIS
I have to transfer data from source to destination using stored procedures result set. There might be some more transformation needed to store the final result in the destination table.
Appreciate an early feedback.

- Use a no-op select statement to "declare" metadata to the pipeline. Since stored procedures don't publish rowset meta-data like tables,views and table-valued functions, the first select statement of a stored procedure is used by the SQLClient OLEDB provider to determine column metadata.
Code SnippetCREATE PROCEDURE dbo.GenMetadata
AS
SET NOCOUNT ON
IF 1 = 0
BEGIN
SELECT CAST(1 as smallint) as Fake
-- Publish metadata
END
-- do real work starting here
DECLARE @x char(1)
SET @x = (SELECT '1')
SELECT cast(@x as smallint)
RETURN

Just create a new instance of "OLE DB Command".
Pick and choose your connection, and call the command as exec <procedure name>
- "Oledb command" Source executes stored procedures.But it does not recognize the output of the stored procedure.
If I have a select statement at the end of the Stored procedure that returns me some columns,then those columns are not recognized by "OLEDB Command" as out put columns.
Is there any advice for executing such stored procedure? - Use a no-op select statement to "declare" metadata to the pipeline.

- It does not work If there are more than one rows are coming out of stored procedure.
- I got it solved on my end by replacing all temporary tables by temporary variables.
Please give an example of what doesn't work for you.
- In the above post it should be table variable not temporary variable.
Conclusion:
It was table variable that Used instead of temporary table. - Hey try with the example below
CREATE PROCEDURE dbo.GenMetadata
AS
SET NOCOUNT ON
CREATE TABLE #test(
[id] [int] NULL,
[Name] [nchar](10) NULL,
[SirName] [nchar](10) NULL
) ON [PRIMARY]
INSERT INTO #test
SELECT '1','A','Z' union all select '2','b','y'
select id,name,SirName
from #test
drop table #test
RETURN
Please let me know the result. With a local temp table created in the stored procedure, use a no-op select statement to "declare" metadata to the pipeline.
Code SnippetIF OBJECT_ID('[dbo].[GenMetadata]', 'P') IS NOT NULL
DROP PROCEDURE [dbo].[GenMetadata]
GO
CREATE PROCEDURE [dbo].[GenMetadata]
AS
SET NOCOUNT ON
IF 1 = 0
BEGIN
-- Publish metadata
SELECT CAST(NULL AS INT) AS id,
CAST(NULL AS NCHAR(10)) AS [Name],
CAST(NULL AS NCHAR(10)) AS SirName
END
-- Do real work starting here
CREATE TABLE #test
(
[id] [int] NULL,
[Name] [nchar](10) NULL,
[SirName] [nchar](10) NULL
)
INSERT INTO #test
SELECT '1',
'A',
'Z'
UNION ALL
SELECT '2',
'b',
'y'
SELECT id,
[Name],
SirName
FROM #test
DROP TABLE #test
RETURN
GO
- Hi Thank you very much..
It is now working fine for the changes you suggested.. - Hello,
With the procedure you have told,SSIS package able to detect output of the stored procedure.
But there another problem introduced bcz of this procedure.Where According to your procedure the SP returns two datasets.
First dataset having 1 row and this is as a result of First select statement.
Second dataset bcz of our actual select query.
So SSIS chooses first dataset,So returns only one row having Null values for all columns.
How to overcome from this? Post a sproc, or usage of the above sproc, which demonstrates the problem (e.g. OPENQUERY, EXEC, INSERT EXEC, so on...)
- what if you want to execute a dynamic script i.e.
Code Blockcreate procedure etl.executeScript @scriptId int, @sessionId varchar(50)
as
set nocount on
declare @script nvarchar(max)
select @script=replace(script,'SESSION-ID',@sessionId)
from etl.script
where id=@scriptId
exec sp_executesql @script
return
exec etl.executeScript 1, 'my session'
basically every script has an id, and a sessionid. ole db command can't pick the meta data coming out of this stored procedure.
in the etl.script table, usually scripts meta data don't change, mostly it's the where class that changes.
when executing the ssis package, script id remains the same, the only thing that change is the sessionid. so for the engine meta data never changes, only the body does. for example a tipical script would look like
select fundid, fundname, descrptin
from dbo.currentsession
where sessionid='SESSION-ID'
so the etl.executeScript stroed procedure replace the sessionid with the passesed sessionid.
any help as to how i can get ole db source to show up the meta data in the columns section.
cheers - I realize this probably isn't the answer you are looking for, but why not just put in the actual SQL, with a parameter for SessionID? What's the point of using a dynamic script if the metadata will always be the same?
- hi jewlch.
basically i'm trying to avoide opening up SSIS for every scrpt change. i only want to open SSIS if there's a meta data change to fix it up. also as you probably know there's a sql command text limit of 4000 characters. sometimes my queries get a little big, (trust me they are optimised to the best extent, but some of them have derived queries with in, so no point in breaking up really) - Hey I am facing another problem that I have multiple #tables and multiple select statement in Store proce and SSIS says # table does not exist. As suggested by him if I put Return any where in between it will come out without executing multiple record set. Please advice
- Try putting a non-executing SELECT statement at the beginning of the procedure, as jaegd showed earlier in this thread.
I've been having similar issues which jaegd's example looked like it would solve. It worked when I tested with a SQL server simple example of a proc using a temp table but failed for a Sybase data source with a more complex proc.
I cannot get this workaround to work with Sybase as the OLEDB source, even with a very simple proc example?
Are there additional complications with using Sybase?
Many thanks,
Chris
- Hi I still can't see the outpout columns in OleDb Command Output Columns
, how can i get the output columns. I want to use them to insert in ole db destination
here is my sp:
create PROCEDURE [dbo].[GetData] (
@user varchar(50)
) AS
set nocount on
-- Publish metadata for ssis
if 1=0
begin
select '' x, '' y, '' z
end
declare @user_tmp table
(
x varchar(max),
y varchar(max),
z varchar(max)
)
insert into @user_tmp
select 'x1' x, 'y1' y, 'z1' z
select distinct * from @user_tmp
set nocount off - i had the same problem--
there is two things u need to do . u need to alter your stored procedure and add is just after the begin statment.
SET NOCOUNT ONSET
kkkkFMTONLY OFF Here is what u need to do alter your stored procdures and just after the
Begin statement do this
SET NOCOUNT ON
SET FMTONLY OFF
kkkk
