Hi,When I add the below line of code to my stored procedure, the performance becoems very poor. Is there any other way I can do i ?
AND CustNum = CASE WHEN ISNULL(@CustNum,0) = 0 THEN CustNum ELSE @CustNum END
Thanks,
PSB
There is always another way to do something. However, from what you posted I doubt anybody can give you much solid advice. All we have is a portion of what appears to be a where clause. This has the appearance of a catch all type query.
Check out this article that explains the issue you are seeing here. http://sqlinthewild.co.za/index.php/2009/03/19/catch-all-queries/[/url]
