Hi everybody!
I have a problem using RDO and stored procedures.
From VB5 I execute this piece of code to retrieve a resultset. I have one in-parameter.

------------------------------------------------------------
Set rsRes = rdCon.OpenResultset("exec spTest 'DEM',
                     rdOpenDynamic,rdConcurReadOnly)
------------------------------------------------------------

The stored procedure "spTest" looks like this:
------------------------------------------------------------
CREATE PROCEDURE spTest
@isokod char (3)
AS
IF @isokod='ALL'
  BEGIN
    select isokod, afnr, sub
    from tblSebtrade
    order by isokod
  END
ELSE
  BEGIN
    select isokod, afnr, sub
    from tblSebtrade
    where isokod=@isokod
    order by isokod
  END
GO
------------------------------------------------------------

And the errormessage :) is:
------------------------------------------------------------
Run-time error '40002':
37000:[Microsoft][ODBC SQL Server Driver][SQL Server]
Cannot open a cursor on a stored procedure that has
anything other than a single select statment in it.
------------------------------------------------------------

I understand the errormessage allright but I have done things like this before (not using RDO). What am I doing wrong this time?
I suspect that I can write the SP in a different way in
order to achieve what I want, but I don't know how...
I would really appreciate help!

                     Best regards // Anders Karlsson

I might be way of base here, but couldn't you just provide a SQL-statement instead of running it as a stored procedure ?

Something like this

Myisokod="DEM" ' or whatever

SqlStatement="select isokod, afnr, sub from tblSebtrade where '" & MyIsokod & "' = 'ALL' OR isokod='" & MyIsokod & "' order by isokod "

Set rsRes = rdCon.OpenResultset(SqlStatement, rdOpenDynamic,rdConcurReadOnly)

Yes I could do that but I dont want to! :)
I have other, more complex, procedures I want to execute
and they all use this technique. I should work and I
cant seem to find the problem.

It seems to me that you are using a cursor on your connection.

Try using a cursorless result set;   rdCon.CursorDriver = rdUseNone


Another solution could be to let the stored procedure produce a temporary table on the server use another openresultset to get the data and then delete the temp table.

I changed the cursortype as you mentioned and it worked
just fine.
This solved my problem and got me going again, thanks!
