Hi all,

I ran a query and it took almost 21 seconds. But I used merge join
and end up 6 seconds.

Select *
table a
inner hash join table b on a.id = b.id

By using this merge or hash join cause any overhead work load? I am very new to SQL Server and I am using 2000, 2005 server.

Thank you very much
Dave
