Test #2:
select name,id from sp_help sysobjects

February 24, 2009 at 1:27 am
can you tell me how should i know the cost of both indexes ?
February 24, 2009 at 1:16 am
I tested the below indexes

I didn't see any difference between them. But which combination will give good performance in the...

I will give you some more example.

Sure.
