ODBC and QA.

Hi.

I have the following SQL Statement ...

SELECT 'CONTRACTS' AS [Database], POH_ORDER_NUMBR, POH_CONTRACT, POH_ACCOUNT FROM CONTRACTS.DBO.POP_HEADER WHERE POH_MU_LOCK=1;

In Query Analyser this returns the correct results.

If I use this query via ODBC, the SQL Profiler reveals the following ...

declare @P1 int
declare @P3 int
declare @P4 int
declare @P5 int
set @P1=0
set @P3=2
set @P4=8193
set @P5=0
exec sp_cursoropen @P1 output, N'SELECT ''CONTRACTS'' AS [Database], POH_ORDER_NUMBR, POH_CONTRACT, POH_ACCOUNT FROM CONTRACTS.DBO.POP_HEADER WHERE POH_MU_LOCK=1;', @P3 output, @P4 output, @P5 output
select @P1, @P3, @P4, @P5

All looks OK.

But the application gets no results.

So.

If I place the above in QA, I get the following results ...

1,330,634,8      2.00      1.00      -1.00

Now the important one is the -1.00

This is the number of rows in the response. -1 means what?

I tried this in QA

declare @P1 int
declare @P3 int
declare @P4 int
declare @P5 int
set @P1=0
set @P3=2
set @P4=8193
set @P5=0
set nocount off
exec sp_cursoropen @P1 output, N'SELECT POH_ORDER_NUMBR, POH_CONTRACT, POH_ACCOUNT FROM CONTRACTS.DBO.POP_HEADER WHERE POH_MU_LOCK=1;', @P3 output, @P4 output, @P5 output
select @P1, @P3, @P4, @P5

exec sp_cursorfetch @P1, 2, 1, 1

and I get a valid row back.

What am I missing that is returning -1 for the number of rows?

Regards,

Richard Quadling.

please try this:

SET NOCOUNT OFF
SELECT 'CONTRACTS' AS [Database], POH_ORDER_NUMBR, POH_CONTRACT, POH_ACCOUNT FROM CONTRACTS.DBO.POP_HEADER WHERE POH_MU_LOCK=1

In QA, they both return valid results.
In my ODBC both return NO results.

What makes this really bizarre is ...

declare @P1 int
declare @P3 int
declare @P4 int
declare @P5 int
set @P1=0
set @P3=2
set @P4=8193
set @P5=0
set nocount off
exec sp_cursoropen @P1 output, N'SELECT DISTINCT SUSORT, COUNT(*) AS ServiceProviders FROM Contracts.dbo.PL_ACCOUNTS WHERE SU_ON_STOP <> 1 AND SUSORT > '''' GROUP BY SUSORT ORDER BY SUSORT', @P3 output, @P4 output, @P5 output
select @P1, @P3, @P4, @P5

exec sp_cursorfetch @P1, 2, 1, 1

returns ...

1,289,928,7      8.00      1.00      1.00


and a valid row.

Hmmm.

I wonder if my interpretation of that last column is correct.

never worked that way, so the only thing I can suggest is to use OLEDB Provider instead of ODBC...

ARGH!!!!

It seems that the ODBC mechanism won't return the number of rows unless there is an order by in the SQL statement.

I was testing 1 statement from a UNION and the UNION has its own ORDER BY clause.

Added the ORDER BY to my 1 SQL line and hey f*cking presto!

ARGH!!!

Thanks for, erm, well, um, listening?

Not sure what to do with this question now.

The answer had nothing to do with the problem (as such).

Note that, as I was the only one contributing, I reduced the waiting time for closing to 0 also :-)
