Dan, I wouldn't say that. What *appears* is the sort, which doesn't take place since data is fetched in sorted order. Rownum is assigned in the order data is fetched, as you say elsewhere. I am pretty sure it's clear in your mind, but it may sound confusing to others. When Naveen said that the rows is ALWAYS assigned before sorting, it's true, even in that case since there is no sort (in the 'shuffling of things in memory' acceptance of the word). -- Regards, Stephane Faroult Oriole Software -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Stephane Faroult 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).
