Static Data Dictionary Views, 44 of 452

ALL_MVIEW_ANALYSIS

ALL_MVIEW_ANALYSIS describes the materialized views accessible to the current user. It provides additional information for analysis by applications. Minimal information is displayed for materialized views that do not support query rewrite (such as materialized views with remote master tables or nondeterministic functions).

Related views:

DBA_MVIEW_ANALYSIS describes all such materialized views in the database.

USER_MVIEW_ANALYSIS describes all such materialized views owned by the current user.

Note:
All of the information in these views is also displayed in ALL_MVIEWS and its related views. Oracle Corporation recommends that you refer to ALL_MVIEWS for this information instead of these views.

Column	Datatype	Null	Description
`OWNER`	`VARCHAR2(30)`	`NOT NULL`	Owner of the materialized view
`MVIEW_NAME`	`VARCHAR2(30)`	`NOT NULL`	Name of the materialized view
`MVIEW_TABLE_OWNER`	`VARCHAR2(30)`	`NOT NULL`	Owner of the container table (see next column)
`CONTAINER_NAME`	`VARCHAR2(30)`		Name of the internal container in which the materialized view data is held. Normally this is the same as `MVIEW_NAME`. For materialized views created in releases before 8.1 (or under pre-8.1 compatibility mode), Oracle attaches the 6-byte prefix SNAP$_. If `MVIEW_NAME` has more than 19 bytes, Oracle truncates the name to 19 bytes and adds a 4-byte sequence number as a suffix to produce a nonambiguous `CONTAINER_NAME`.
`LAST_REFRESH_SCN`	`NUMBER`		System change number (SCN) of the last refresh operation
`LAST_REFRESH_DATE`	`DATE`		SYSDATE of the last refresh
`REFRESH_METHOD`	`VARCHAR2(8)`		Default refresh method: `FORCE`, `FAST`, `COMPLETE`, or `NONE`
`SUMMARY`	`VARCHAR2(1)`		Whether this materialized view includes a `GROUP` `BY` clause or aggregation (`Y` \| `N`)
`FULLREFRESHTIM`	`NUMBER`		Approximate refresh time, in seconds, for full refresh (defined only when `SUMMARY` = Y)
`INCREFRESHTIM`	`NUMBER`		Approximate refresh time, in seconds, for fast refresh (defined only when `SUMMARY` = Y)
`CONTAINS_VIEWS`	`VARCHAR2(1)`		Whether this materialized view contains a view in its definition (Y \| N)
`UNUSABLE`	`VARCHAR2(1)`		Whether this materialized view is `UNUSABLE` (inconsistent data) (Y \| N). A materialized view can be UNUSABLE if a system failure occurs during a full refresh.
`RESTRICTED_SYNTAX`	`VARCHAR2(1)`		Whether this materialized view had a restriction in its defining query that limits the use of query rewrite (Y \| N). More complete information is provided by the `REWRITE_CAPABILITY` column of the `ALL_`, `DBA_`, and `USER_MVIEWS` views.
`INC_REFRESHABLE`	`VARCHAR2(1)`		Whether this materialized view can be fast refreshed (Y \| N)
`KNOWN_STALE`	`VARCHAR2(1)`		Whether the data contained in the materialized view is known to be inconsistent with the master table data because that has been updated since the last successful refresh (Y \| N)
`INVALID`	`VARCHAR2(1)`		Whether this materialized view is in an invalid state (inconsistent metadata) (Y \| N)
`REWRITE_ENABLED`	`VARCHAR2(1)`		Whether this materialized view is currently enabled for query rewrite (Y \| N)
`QUERY_LEN`	`NUMBER`	`NOT NULL`	The length (in bytes) of the query field
`QUERY`	`LONG`	`NOT NULL`	SELECT expression of the materialized view definition
`REVISION`	`NUMBER`		Reserved for internal use
