I have to ask...Did you wait until the query finished? You can't have actual rows until you have actual results to count. If there's some bug in DBMS_XPLAN then I suppose the next option I would choose would be a 10053 trace so you'd know what the CBO is thinking. Thanks, T. J.

From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Stephens, Chris Sent: Friday, February 25, 2011 2:38 PM To: oracle-l@xxxxxxxxxxxxx Subject: dbms_xplan + allstats 126.96.36.199 on RHEL I'm working on some SQL that suffers from some horrible cardinality estimate problems due to dummy rows that screw up the columns stats. Everything was going fine this morning but for some reason I can't get an execution plan to show me the a-rows now. I've tried the /*+ gather_plan_stats */ hint. I've tried "alter session set statistics_level=ALL" I've tried "alter system set statistics_level=ALL" I've even tried bouncing the database. select * from table(dbms_xplan.display_cursor('&sql_id','&child_no','allstats')) / ....will not show me the a-rows. Anybody have an hints to help me out?
