Updatable Views

INSERT, UPDATE and DELETE statements may be used on views.

The operation is then performed on the base table upon which the view is defined. However, certain views may not be updated (for example a view containing DISTINCT values, where a single row in the view may represent several rows in the base table).

A view is not updatable if any of the following conditions are true:

Note: By defining an INSTEAD OF trigger any view can be made updatable. If all the INSTEAD OF triggers on the view are dropped, the view will revert to not updatable if one or more of the above conditions are true.
