FIRST_ROWS would alter the behavior regardless of the number of rows. -----Original Message----- Jay Wade Sent: Tuesday, January 06, 2004 1:44 PM To: Multiple recipients of list ORACLE-L
Hello: I was looking through some OCP questions posted on the web and came across the one below. I believe the answer is (D), because the join type would be dependent on the number of rows within the table. Is this correct or does the OPTIMIZER_MODE set to FIRST_ROWS alter this behavior? The cost-based optimizer can choose between a nested loops join and a sort merge join operation. All tables are analyzed and the OPTIMIZER_MODE is set to FIRST_ROWS. Which execution plan will be the result? a. The sort-merge join. b. The nested loops join. c. This depends on some sort parameter values. d. This depends on the number of rows in each table. _________________________________________________________________ Check your PC for viruses with the FREE McAfee online computer scan. http://clinic.mcafee.com/clinic/ibuy/campaign.asp?cid=3963 -- Please see the official ORACLE-L FAQ: http://www.orafaq.net -- Author: Jay Wade INET: [EMAIL PROTECTED] Fat City Network Services -- 858-538-5051 http://www.fatcity.com San Diego, California -- Mailing list and web hosting services --------------------------------------------------------------------- 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).
