Subj:   Re: How to get confidence on derived spool
 
From:   Ballinger, Carrie

As part of query rewrite and optimizer cost enhancement functionalities in Release 12.0, derived tables will be handled more optimally. Demographic information will no longer be lost and you can expect to see higher confidence levels because you will no longer have to rely on default estimates.


Thanks, -Carrie
