There are two possible statuses for materialized views:
Enabled The materialized view has been successfully compiled and is available for use by the database server. An enabled materialized view may not have data in it. For example, if you truncate the data from an enabled materialized view, it changes to enabled and uninitialized. A materialized view can be initialized but empty if there is no data in the underlying tables that satisfies the definition for the materialized view. This is not the same as a materialized view that has no data in it because it is not initialized.
Disabled The materialized view has been explicitly disabled, for example by using the ALTER MATERIALIZED VIEW...DISABLE statement. When you disable a materialized view, the data and indexes for the view are dropped. Also, when you disable an immediate view, it is changed to a manual view.
To determine whether a view is enabled or disabled, use the sa_materialized_view_info system procedure to return the Status property for the view.
