HTH Lisa -----Original Message----- From:   Cherie_Machler@gelco.com [SMTP:Cherie_Machler@gelco.com] Sent:   Monday, August 27, 2001 3:11 PM To:     Multiple recipients of list ORACLE-L Subject:        I am running tkprof and explain plan on the following SQL statement: SELECT DISTINCT CNFR_NO, SPLT_PAY_TYPE, ACH_AMT FROM whse_dbo.ACH_TRAN WHERE ACCT_NO = '46807' AND         TRUNC(TRAN_DT) = TRUNC(TO_DATE('20-JUL-01','DD-MON-YY')) AND         STATUS = '2' AND         CNFR_NO >0 AND         (SPLT_PAY_TYPE = '810' OR         SPLT_PAY_TYPE = '820' ); I'm not really looking for advice on tuning this query but rather just wanted to have some general questions answered regarding the results i got using tkprof. This is the first time I've ever run tkprof on a statement and gotten an explain plan with :Q in it (followed by numbers).  What does the :Q mean? Also, there is not hint embedded in the select statement I ran but the explain plan output shows hints in the explain plan.  Or at least the explain plan list the output in hint format.   Why is it doing that, when there were no hints in the original source?
