Answer Posted / guest
Cause: If there is a semi join in the query, then Query
Rewrite will create (select distinct <pk-list>, <ref-col>
from mjv) where <pk-list> is the list of rowids/pk of all
mjv tables that don't correspond to a right side of a
semi-join and <ref-col> are their columns. Query Rewrite
will not occur if a join from the materialized view cannot
match the semi-join from the query.
Action: none
