Forget my original question...

Make believe that this has nothing to do with cursors, stored procs or anything else. I just want to know if anyone has ever seen "Primary Key" assigned to a column in a table var, crash a stored proc.

That's it. That's the entire question.

I don't mean to sound ungratefulm but many people have posted answers to a question I am not asking. I am not attempting to speed up a stored proc, I am not attempting to alter my code. The code I have works fine. I am just asking if anyone else has ever seen this behavior in SQL 2000.

Thanks
