-- @awr/awr_sqlstats_unstable.sql version 0.1 BETA by Tanel Poder
--
-- detect sql_id that use a varying amount of *elapsed time per execution* across different plan hash values
-- or across AWR time ranges
--
-- usage examples:
-- a) typical use - show SQL_IDs from last 2 weeks that have different plans with different
-- elapsed time per execution (per plan)
--
-- @awr/awr_sqlstats_unstable sql_id plan_hash_value sysdate-14 sysdate
--
-- b) special case use with SQL using literals (note that AWR may not persist many of these queries)
-- as due to literals these tend to be executed only once
--
-- @awr/awr_sqlstats_unstable force_matching_signature plan_hash_value sysdate-14 sysdate
--
-- c) advanced use - show cases where *the same plan* (same plan hash value) uses different amounts
-- of elapsed time per execution over time. so it's not a *plan* flipping problem
--
-- @awr/awr_sqlstats_unstable sql_id,plan_hash_value begin_interval_time sysdate-14 sysdate
--
-- Once you have found a SQL_ID of interest, you can drill down into its actual plans and elapsed times using:
--
-- @awr/awr_sqlstats_per_exec &sqlid % sysdate-14 sysdate
--
--
-- other:
-- Inspired by Kerry Osborne's unstable_plans.sql script - http://kerryosborne.oracle-guy.com/2008/10/unstable-plans/
