    • Fully Compatible

    Description

      The query optimizer currently generates a query plan which is cached and re-used based on the normalized "shape" of the query predicate and sort criteria.

      1. Querying
        DBA's should be able to hint a query by plan id. This should be able to be set by a DBA on the server-side in addition to the current technique of putting the hint into the application itself.
