     Currently, views are read only: the system will not allow an insert,
     update, or delete on a view.  You can get the effect of an updatable

+    view by creating INSTEAD triggers on the view, which
+    must convert attempted inserts, etc. on the view into
     appropriate actions on other tables.  For more information see
