Oooh, good thought --- but you are explaining it backwards. If clientes
was made with CREATE VIEW, then an INSERT into clientes would in fact
insert data into clientes --- but you'd never see it again, because any
SELECT from clientes would be redirected to whatever the view is of.
(I've been burnt by that myself ;-).)
If you want to insert/update on a view, you need to provide ON INSERT,
ON UPDATE, ON DELETE rules that tell how to modify the underlying tables
appropriately. The system will *not* try to intuit these for you.
