Execute stored proc with OPENQUERY

问题

I have SQL Server 2008 with a linked Sybase server and I am trying to execute a stored procedure on the Sybase server using OPENQUERY. If I have a stored proc that doesn't take parameters it succeeds fine. If I have a stored proc with parameters it fails. I even tried a very basic stored proc that only took an int an that still failed. Below is the syntax I am using:

select * from 
OPENQUERY([LINKSERVER],'exec database.user.my_stored_proc ''AT'',''XXXX%'',''1111'',1')

Msg 7357, Level 16, State 2, Line 3 Cannot process the object "exec database.user.my_stored_proc 'AT','XXXX%','1111',1". The OLE DB provider "ASEOLEDB" for linked server "LINKSERVER" indicates that either the object has no columns or the current user does not have permissions on that object.

As the proc will execute just fine without parameters, I don't think it is a permission issue.

Linked Servers and OPENQUERY, Gems to MS SQL Server...that are wolves in sheep clothing. I've found the following solutions to work when dealing with parameters

If the SP is basically just SELECT statements, the move the same to a VIEW and just pass SQL statements via OPENQUERY.
Build the OPENQUERY as a string and then use execute_sql.

This worked for me,

SELECT * FROM OPENQUERY(LOCALSERVER, 'SET FMTONLY OFF EXEC snr.dbo.GetAllSignals @controlRunId = 25, @experimentRunId = 26')

I was creating temporary tables, and that's why i got access denied

I create a sp that doesn't return any value and it doesn't work. Your SP in mysql have to return a value! for example I do this in "mysql":

CREATE DEFINER=`root`@`localhost` PROCEDURE `MyPro`(IN `Name` VARCHAR(50), IN `Id` INT, OUT `Result` INT)
MODIFIES SQL DATA
BEGIN
DECLARE Result INT;
    SET Result = 0;
INSERT into MyTable (Id,Name)  VALUES(Id,Name);
SELECT Result;

END

That "Id" and "Name" is input parameter and "Result" is output parameter and create linked server in SQL SERVER and call it like this:

select * from openquery
(
    Test,'call mydb.MyPro(''Name'',''16'', @P0);'
)

It works for me :D

You could also see if it works to precede exec with SET FMTONLY ON:

OPENQUERY([LINKSERVER],'SET FMTONLY ON; exec database.user.my_stored_proc ''AT'',''XXXX%'',''1111'',1')

If you try this and it works, you should probably Google FMTONLY+OPENQUERY to get an idea of what it means.

Try this,

SELECT * FROM OPENQUERY(linked_server_name, 'SELECT postgres_procedure_name (parameters)');

回答6:

I experienced a very similar issue, but my SP wasn't taking any parameters. I tried experimenting with altering the query sent through the openquery to include 'SET NOCOUNT ON' and 'SET FMTONLY OFF' but this had no difference.

The only solution that worked for my stored procedure was dropping the existing version, and altering the code to specifically 'SET NOCOUNT ON'

After doing this I was able to successfully run my stored proc through my linked server connection.
