Subj:   Re: Performance Tunning and Explain
 
From:   Roth, David

Just have to give a caution here. Using the Diagnostic helpstats on for session; command only gives you a list of "possible" statistics that could help the query.

Do NOT just blindly apply all of them!

You must select and test each one to determine if it gives you the performance you desire.


Regards,

Dave
