query performance tuning

Hi
Where can I find good resources re: peformance tuning of queries / indexes ,
using EXPLAIN etc ?
Thanks
BruceBecause you have EXPLAIN in capitals I am going to presume you either
1. Want the SQL Server equivalent to Oracle's EXPLAIN PLAN
2. Have the wrong Newsgroup
Presuming #1 you can look at.
SET SHOWPLAN_ALL ON
once you have that then you can start to look to articles like this
http://www.sql-server-performance.com/query_execution_plan_analysis.asp
or anything on the subject by Kalen Delaney.
