AbdelMohsen writes "Optional PArameters VS Dynamic SQL
Dears,

I'm Working on aa ASP.NET Website (MS SQL SWERVER 2000) which I have to search in the Data Base using optional parameters FOR STORED PROCEDURE
I tried
(Col=@PAram OR Param is Null)
but this affected the performance ...
As I may have optional parameter from 6 ~ 15 parameter in some cases..

I saw many Articles on the web about how to build a dynamic SQL Query but I don't know the affect on security & where to build the query in my Code or in the SQL Server which one is better,
In Performance & Security.

Please advice..

Best Regards"

How badly does it affect performance? I cant see dynamic sql doing a much better job? Got any code to post? Got any indexes on the fields? Explain the table structure. And all that good stuff.
