RE: rollback use query
Kirti and Yosi, It's a good idea to not argue with Anita! :) Oh puhleeze!! Argue with me all you want, especially when I'm wrong. I'm a big girl, I can take it ;) Now if you want to convince my boyfriend not to argue with me, be my guest! You're both correct and I should have been more specific in my response. The rollback generated is due to the dd changes for creating the new table and extent allocation, so it's no where near the amount used for the equivalent create table and conventional inserts. It's not exclusively DDL, though as it does require a non-system RBS, whereas a simple create table statement doesn't. -- Anita --- Deshpande, Kirti [EMAIL PROTECTED] wrote: Hi Yosi, It's a good idea to not argue with Anita! :) Just do a simple test to confirm.

RE: rollback use query
Right. I knew that part too, and I'm feeling much better now. I was beginning to get a queasy uneasy feeling there, where your world spins out of focus type thing. :-) Thanks, Anita. -Original Message- From: A.

RE: rollback use query
Hi Yosi, I'd hate to argue with Anita, but I'm pretty sure that rollback won't be used on CTAS, since it's ddl. CTAS or any DDL for that matter *will* need to write to SYS tables - (UET$, FET$ in this simple case as it needs to preserve information about extents allocated, etc.) and this generates a small amount of redo. Not that I'd argue with Anita anyway 8-) John Kanagaraj -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: John Kanagaraj 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).
