You can also query the AWR:
SQL> select min(snap_id), max(snap_id) from dba_hist_sqlstat where
sql_id='1nh4y7yurm73g';
MIN(SNAP_ID) MAX(SNAP_ID)
------------ ------------
8301 8414
SQL> col first format a35
SQL> col last format a35
SQL> select min(begin_interval_time) first, max(end_interval_time) last
2 from dba_hist_sqlstat natural join dba_hist_snapshot
3 where sql_id='1nh4y7yurm73g';
FIRST LAST

Can you not write the dbms_xplan.display to an interim table (create
table xx as select * from ...) and then join that with the
last_load_time from v$sql based on the sql_id in both tables

Hello.
I have found that, the following sql is very helpful in finding out the
historical (What is in AWR) plan of a given SQL_ID.
select * from table (sys.dbms_xplan.display_awr('&Your_SQL_ID')) ;
But so far I could not figure out, how I can figure out WHEN this plan was
in effect. Is there a way, I can corelate this plan to Sysdate or in other
words, find out when this plan was in effect?
Thanks for your insight,
Shiva
