I'm having trouble determining the number of rows in a cursor. Here is a snippet of code:
DECLARE curPT CURSOR FAST_FORWARD FOR SELECT * FROM PT WHERE cGID = '1234567890'
OPEN curPT
PRINT @@ROWCOUNT
This always prints 0. I know that 2 records exist in table PT.

@@ROWCOUNT returns the number of rows impacted by the last statement, which in this case is the OPEN. The OPEN didn't impact any results, and that is why you got a zero.
What you need is a STATIC cursor and @@CURSOR_ROWS
Good Luck!

[font="Verdana"]Hi,
But do u can elaborate its performance degradation? You may know already, and ppl suggests another to this as [highlight]Count()[/highlight] function, but i am unable to fix it up in code.
But again Count() is also controversial. Any good/excellent alternative!
Another one was of [highlight]INSENSITIVE[/highlight] .... . but what's its results on performance... !!!
Thank you.[/font]
