There's gv$sqlstats, and dba_hist_sqlstat (for historical sqls).

On gv$sqlstats there's ELAPSED_TIME which is micro seconds so you can
convert that to milliseconds and divide ELAPSED_TIME / EXECUTIONS to get
time per execution. For example, I use (ELAPSED_TIME/1000000)/EXECUTIONS
to get seconds_per_execution.

On dba_hist_sqlstat, there EXECUTIONS_DELTA and ELAPSED_TIME_DELTA. Elap
Time Delta is again microseconds , so divide to get your conversion. Then
divide that by executions_delta to get your time per execution.

Thanks,
Chris Taylor

You can use v$sql to write custom pl/sql job

Or use fine grained auditing. That's what it is meant for.

dbms_workload_repository.add_colored_sql()

Supply the sql_id and the SQL will be recorded in the AWR even if it doesn't meet any of the limits set for normal "SQL ordered by ... "


There's a limit of 100 sql_ids that can be "colored" - then you get error:

ORA-13534: Current SQL count(100) reached maximum allowed (100)
ORA-06512: at "SYS.DBMS_WORKLOAD_REPOSITORY", line 751

dbms_workload_repository.remove_colored_sql() to remove them from the hit list


Regards
Jonathan Lewis

You can also get this from ASH

See example here
https://gist.github.com/karlarao/3ba0ead11336e2401a552588b9941e24

You can filter <1sec or <10sec queries using @ash_elap2 on the example
