Freddy,

A couple of weeks ago you produced a snapshot for me to test a 0.82
behaviour for SQLNumResultCols being called in advance of SQLExecute.
I was on the road for a couple of weeks and couldn't get to testing
it until now.  I tested the one example that produced the problem and
it no longer occurs.  I haven't tested all of our use cases, however,
I'd say that this patch you did is at least an improvement.  Could you
still include the patch in the RC?

See below for a paste of the last bits of our exchange.

Thanks,
DK.

Subject: [freetds] SQLNumResultCols before SQLExecute

Please try attached snapshot. It reproduce a 0.82 behavior that seems to work.
I'll backport to 0.91 if it works (patch is quite small and all tests passed).

Regards
