    QSM-01222: materialized view string is less optimal than string

    Reason for the Error

    Query Rewrite always chooses the most optimal materialized view based on certain parameters, such as cardinality of the materialized view, number of joins etc. The materialized view specified was found to be less optimal.

    Solution

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