can we update a view which is created from two tables
Answer Posted / sankar
It is not possible to update a view which is created from
two tables.Actually when we update any viewtha first the
view has been updated followed by the base table.If we use
instead of trigger then the base be table will updated
first not the view.Because the view is stored in database
as a query.Once the base table will be changed,the view
query will hit the base table and reflects the changes.But
I think that's not the desired answer.
