Hi,
I have a "simple" problem:
From the table "A" I have to exclude phone numbers present in table "B" and
those numbers that are also in the table "C"
So far I've used this sql that works only in A-B but I would like to have C
here aswell:
select o.PHONE
from B b, A a, C c
where b.phone(+)=a.phone
and b.phone is null

If u can use union even this would work :
SELECT phone
FROM a
WHERE phone NOT
IN (
SELECT phone
FROM c
UNION SELECT phone
FROM b
)
