Thanks Charles for the input.

We have a 3rd party designing applications using Visual Studio and are
experiencing some performance issues.

They suggested that creating stored procedures might resolve the
performance issues.

They suggested passing the SQL Statement as a parameter to the
procedure.

If you have a snippet that you could provide, that would be great.

I have looked and continue to look at the redbook for guidance.

Thanks.

subject: Re: SQL Stored Procedure

James,

I won't say it can't be done, but it's going to be very, very hard to
do what you want.

It seems as if you want to provide your own STRSQL type application,
why?  What's the business need, perhaps there is a better way.

If the caller can use SQL to call your procedure, why can't the caller
simply run the statement directly?
For a roll your own STRSQL application, an SQL stored procedure is
probably a poor choice in the first place.

In any event, as you've currently coded it, you're going about the
task completely wrong.

You can't CLOSE a cursor you want returned to a caller.
You also can't FETCH from the cursor you want returned, that's the
caller's job.

HTH,
Charles
