QSM-01125

a more optimal set operator materialized view than string was used to rewrite

Cause

Query Rewrite always chooses the most optimal set operator materialized view based on parameters, such as cardinality of the set operator materialized view, number of branches that the set operator materialized view can rewrite etc. The set operator materialized view specified was found to be less optimal.


Action

To force using a set operator materialized view, consider using a rewrite hint.
