Ok, first misconception reached. I thought analyze didn't handle partitioned segments but a quick RTFM and trace shows normal range partition pruning with Analyze generated stats. So is there an advantage of dbms_stats here? Or is the advantage the addition features dbms_stats brings withit?

Subject: Analyze vs. dbms_stats with Partitioning

I am in the initial stages of experimenting with Partitioning, and therefore also moving from analyze to dbms_stats. Does one have to delete the analyze-created stats before generating the dbms_stats-based ones, or is that a Oracle-legend I heard/read in the distant past? Is there anyway to determine which means was used to generate the stats after the fact?

This is for V9.2.0.5 on Tru64.

Thanks,
Mike H

P.S. Am reading several articles by ANanda and JLewis on the subject.
