Column	Datatype	NULL	Description
`OWNER`	`VARCHAR2(30)`	`NOT NULL`	Schema in which the materialized view was created
`MVIEW_NAME`	`VARCHAR2(30)`	`NOT NULL`	Name of the materialized view
`CONTAINER_NAME`	`VARCHAR2(30)`	`NOT NULL`	Name of the container in which the materialized view's data is held. Normally this is the same as `MVIEW_NAME`. For materialized views created prior to Oracle8i, the Oracle Database attaches the 6-byte prefix `SNAP$_`. If `MVIEW_NAME` has more than 19 bytes, then the Oracle Database truncates the name to 19 bytes and may add a 4-byte sequence number as a suffix to produce a nonambiguous `CONTAINER_NAME`.
`QUERY`	`LONG`		Query that defines the materialized view
`QUERY_LEN`	`NUMBER(38)`		Length (in bytes) of the defining query
`UPDATABLE`	`VARCHAR2(1)`		Indicates whether the materialized view is updatable (`Y`) or not (`N`)
`UPDATE_LOG`	`VARCHAR2(30)`		For updatable materialized views, the filename of the update log
`MASTER_ROLLBACK_SEG`	`VARCHAR2(30)`		Rollback segment for the master site or the master materialized view site
`MASTER_LINK`	`VARCHAR2(128)`		Database link for the master site or the master materialized view site
`REWRITE_ENABLED`	`VARCHAR2(1)`		Indicates whether rewrite is enabled (`Y`) or not (`N`)
`REWRITE_CAPABILITY`	`VARCHAR2(9)`		Indicates whether the materialized view is eligible for rewrite, and if so, what rules must be followed: `NONE` - Materialized view cannot be used for rewrite, because rewrite is disallowed or prevented `TEXTMATCH` - Defining query of the materialized view contained restrictions on the use of query rewrite `GENERAL` - Defining query of the materialized view contained no restrictions on the use of query rewrite, so the Oracle Database can apply any rewrite rule that is supported
`REFRESH_MODE`	`VARCHAR2(6)`		Refresh mode of the materialized view: `DEMAND` - Oracle Database refreshes this materialized view whenever an appropriate refresh procedure is called `COMMIT` - Oracle Database refreshes this materialized view when a transaction on one of the materialized view's masters commits `NEVER` - Oracle Database never refreshes this materialized view
`REFRESH_METHOD`	`VARCHAR2(8)`		Default method used to refresh the materialized view (can be overridden through the API): `COMPLETE` (`C`) - Materialized view is completely refreshed from the masters `FORCE` (`?`) - Oracle Database performs a fast refresh if possible, otherwise a complete refresh `FAST` (`F`) - Oracle Database performs an incremental refresh applying changes that correspond to changes in the masters since the last refresh `NEVER` (`N`) - User specified that the Oracle Database should not refresh this materialized view
`BUILD_MODE`	`VARCHAR2(9)`		Indicates how the materialized view was populated during creation: `IMMEDIATE` - Populated from the masters during creation `DEFERRED` - Not populated during creation. Must be explicitly populated later by the user. `PREBUILT` - Populated with an existing table during creation. The relationship of the contents of this prebuilt table to the materialized view's masters is unknown to the Oracle Database.
`FAST_REFRESHABLE`	`VARCHAR2(18)`		Indicates whether the materialized view is eligible for incremental (fast) refresh. The Oracle Database calculates this value statically, based on the materialized view definition query: `NO` - Materialized view is not fast refreshable, and hence is complex `DIRLOAD` - Fast refresh is supported only for direct loads `DML` - Fast refresh is supported only for DML operations `DIRLOAD_DML` - Fast refresh is supported for both direct loads and DML operations `DIRLOAD_LIMITEDDML` - Fast refresh is supported for direct loads and a subset of DML operations
`LAST_REFRESH_TYPE`	`VARCHAR2(8)`		Method used for the most recent refresh: `COMPLETE` - Most recent refresh was complete `FAST` - Most recent refresh was fast (incremental) `NA` - Materialized view has not yet been refreshed (for example, if it was created `DEFERRED`)
`LAST_REFRESH_DATE`	`DATE`		Date on which the materialized view was most recently refreshed. Blank if not yet populated.
`STALENESS`	`VARCHAR2(19)`		Relationship between the contents of the materialized view and the contents of the materialized view's masters: `FRESH` - Materialized view is a read-consistent view of the current state of its masters `STALE` - Materialized view is out of date because one or more of its masters has changed. If the materialized view was `FRESH` before it became `STALE`, then it is a read-consistent view of a former state of its masters. `UNUSABLE` - Materialized view is not a read-consistent view of its masters from any point in time `UNKNOWN` - Oracle Database does not know whether the materialized view is in a read-consistent view of its masters from any point in time (this is the case for materialized views created on prebuilt tables) `UNDEFINED` - Materialized view has remote masters. The concept of staleness is not defined for such materialized views.
`AFTER_FAST_REFRESH`	`VARCHAR2(19)`		Specifies the staleness value that will occur if a fast refresh is applied to this materialized view. Its values are the same as for the `STALENESS` column, plus the value `NA`, which is used when fast refresh is not applicable to this materialized view.
`UNKNOWN_PREBUILT`	`VARCHAR2(1)`		Indicates whether the materialized view is prebuilt (`Y`) or not (`N`)
`UNKNOWN_PLSQL_FUNC`	`VARCHAR2(1)`		Indicates whether the materialized view contains PL/SQL functions (`Y`) or not (`N`)
`UNKNOWN_EXTERNAL_TABLE`	`VARCHAR2(1)`		Indicates whether the materialized view contains external tables (`Y`) or not (`N`)
`UNKNOWN_CONSIDER_FRESH`	`VARCHAR2(1)`		Indicates whether the materialized view is considered fresh (`Y`) or not (`N`)
`UNKNOWN_IMPORT`	`VARCHAR2(1)`		Indicates whether the materialized view is imported (`Y`) or not (`N`)
`UNKNOWN_TRUSTED_FD`	`VARCHAR2(1)`		Indicates whether the materialized view uses trusted constraints for refresh (`Y`) or not (`N`)
`COMPILE_STATE`	`VARCHAR2(19)`		Validity of the materialized view with respect to the objects upon which it depends: `VALID` - Materialized view has been validated without error, and no object upon which it depends has changed since the last validation `NEEDS_COMPILE` - Some object upon which the materialized view depends has changed. An `ALTER MATERIALIZED VIEW...COMPILE` statement is required to validate this materialized view. `ERROR` - Materialized view has been validated with one or more errors
`USE_NO_INDEX`	`VARCHAR2(1)`		Indicates whether the materialized view was created using the `USING NO INDEX` clause (`Y`) or the materialized view was created with the default index (`N`). The `USING NO INDEX` clause suppresses the creation of the default index.
`STALE_SINCE`	`DATE`		Time from when the materialized view became stale
