Does someone have any ideas? SELECT count(b.award_number) FROM RF_BALANCE_T b, rf_security_by_dceid s WHERE (s.award_number = 'ALL') OR (b.award_number = s.award_number AND s.project_number = 'ALL') OR (b.award_number = s.award_number AND b.project_number= s.project_number AND s.task_number = 'ALL') OR (b.award_number = s.award_number AND b.project_number= s.project_number AND b.task_number = s.task_number) _________________________________________________________________ High-speed users-be more efficient online with the new MSN Premium Internet Software. http://join.msn.com/?pgmarket=en-us&page=byoa/prem&ST=1 -- Please see the official ORACLE-L FAQ: http://www.orafaq.net -- Author: David Boyd 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).
