Why I'm doing:
Query cannot be rewritten by mv-texted based rewrite if mv has
order by
and query hasorder by
even if the defined query are exactly the same because subquery will eliminatethe order by
in the subquery which cause text match failed:What I'm doing:
materialized_view_subuqery_text_match_max_count
parameter which means the real sub query match count limit.Fixes #issue
