Oracle Error Message

QSM-01298: materialized view string clause more restrictive than query string clause

Reason for the Error

The materialized view contains a selection condition in the WHERE or HAVING clause that is more restrictive than the corresponding selection condition in the request query.

Solution

Change the selection criteria in the request query to be at least as restrictive as the selection criteria in the materialized view, or drop and recreate the materialized view using less restrictive selection criteria.
