Answer / 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.

Answer / duong
Views in all versions of SQL Server are updatable (can be the target of UPDATE, DELETE, or INSERT statements), as long as the modification affects only one of the base tables referenced by the view, for example:
-- Increase the prices for publisher '0736' by 10%.
UPDATE titleview
SET price = price * 1.10
WHERE pub_id = '0736'
GO

You can't do it in data bound mode for SQL Server 2000.It
gives an error called
"Insufficient key column information for updating or refreshing"
