Hi everybody
I've read a quite old posting about the impossibility of updating a
view.
e.g.
Let t1 (Id, balance) and t2 (id, amount) be two tables
DEFINE VIEW U AS SELECT balance, amount FROM t1, t2 WHERE t1.id=t2.id;
UPDATE U SET balance=balance+amount
without writing a rule
I found a simpler way to do the job I wanted done
UPDATE t1 SET balance = balance+t2.amount WHERE EXISTS (SELECT *
FROM t2 WHERE t2.id = t1.id)
DOES WORK PROPERLY.
