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.

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?
