Yes, you can query the AWR - but the queries provided below only show the first & last time of the sql_id, not the specific plan. To find the details of the plan, you'd want to run something like this: select min(snap_time), max(snap_time) from dba_hist_active_sess_history where sql_plan_hash_value = <known plan_hash_value> Or: select sql_plan_hash_value, min(snap_time), max(snap_time) from dba_hist_active_sess_history where sql_id = <your sql_id> group by sql_plan_hash_value; And you can query dba_hist_sql_plan for the details of any given plan in the AWR. Or, better yet: Run $ORACLE_HOME/rdbms/admin/awrsqrpt.sql This will give you a nicely formatted output of all plans currently in the AWR for a given sql_id, along with the first and last snap_ids, executions stats, etc. for each plan and it's available in your choice of HTML or text.
