Materialized view properties are used by the optimizer when evaluating whether to use a view. The following list describes the properties for a materialized view that are returned by the sa_materialized_view_info system procedure:
Status Indicates whether the view is enabled or disabled.
DataStatus Reflects the state of the data in the view. For example, it tells you whether the view is initialized and whether the view is stale. Manual views are stale if data in the underlying tables has changed since the last time the materialized view was refreshed. Immediate views are never stale.
ViewLastRefreshed Indicates the last time the view was refreshed.
DateLastModified Indicates the most recent time the data in any underlying table was modified if the view is stale.
AvailForOptimization Reflects whether the view is available for use by the optimizer.
RefreshType Indicates whether it is a manual view or an immediate view.
For the list of possible values for each property, use the sa_materialized_view_info system procedure.
While there is no property that tells you whether a manual view can be converted to an immediate view, you can determine this by using the sa_materialized_view_can_be_immediate system procedure.
