  • 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.

Note:

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" before Oracle8i and that were never altered to enable query rewrite.
