Subj:   Re: Dropping stats on indexes
 
From:   Roth, David

Single column index stats are stored in the same table as single column stats.

Multicolumn index stats are not, so there is a difference between stats on multiple columns and stats on a multi-column index.

This is why I always recommend using named indexes and collection on the named index. You cannot rely on column statistics to support your indexes.
