ALL_MVIEW_DETAIL_RELATIONS describes the named detail relations that are either specified in the FROM list of the subquery that defines a materialized view accessible to the current user, or that are indirectly referenced through views in that FROM list. Inline views in the materialized view definition are not represented in this view or the related views.
DBA_MVIEW_DETAIL_RELATIONS describes all such detail relations defined for all materialized views in the database.
USER_MVIEW_DETAIL_RELATIONS describes such detail relations defined for all materialized views owned by the current user.
Note:
All three views exclude materialized views that reference remote tables or that includes references to a nonstatic value such asSYSDATE 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.| Column | Datatype | NULL | Description |
