I see a new MYTH developing, and that is that RULE is better than COST. I have to believe that some thought has been put into the CBO. I also have to believe that if we all switched to RULE in the next ten minutes that the overwhelming response would not be "Wow, look at the incredible improvement in performance!"

Maybe setting optimizer mode to first_rows would do the same. Then you would still be using CBO, allowing your SQL to take advantage of optimizations that are not available with RBO. -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Post, Ethan INET: [EMAIL PROTECTED] Fat City Network Services -- (858) 538-5051 FAX: (858) 538-5051 San Diego, California -- Public Internet access / Mailing Lists -------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB ORACLE-L (or the name of mailing list you want to be removed from).
