Subject: Looking for an efficient way to replace efficient NOT IN when landling very large data
Date: Tue, 11 Apr 2023 10:27:59 +0100
Message-ID: <CA+i5JwYoxnYGHXn41AgnN9iJP8FCMDMozgzsn5hc0tvhSSMNVg@mail.gmail.com> (raw)

Select a.id, a.name, b.id, b.name from a_large_table a, definitive b where (
a.id, b.name) not in
(select b.id, b.name from definitive b)

is very slow.

Is there a faster way to do so?

Regards,

David
