ALL_MVIEW_JOINS

ALL_MVIEW_JOINS describes joins between two columns in the WHERE clause of the subquery that defines a materialized view accessible to the current user.

Related views:

DBA_MVIEW_JOINS describes all such joins for all materialized views in the database.
USER_MVIEW_JOINS describes such joins for all materialized views owned by the current user.

All three views exclude materialized views that reference remote tables or that includes references to a nonstatic value such as SYSDATE or USER. These views also exclude materialized views that were created as "snapshots" prior to Oracle8i and that were never altered to enable query rewrite.
