Subject: Global setting for ORDER BY ... NULLS FIRST / LAST
Date: Tue, 1 Mar 2022 14:16:23 +0000
Message-ID: <DBAP191MB12893AA929975291A05E2938B0029@DBAP191MB1289.EURP191.PROD.OUTLOOK.COM> (raw)

Hello!

Is there a global PostgreSQL server setting or SQL session parameter that defines the default for   ORDER BY ... NULLS FIRST / LAST ?

Assuming that it would be something like "NULL is lowest value, or NULL is highest value", to get the expected behavior when using ASC/DESC options of ORDER BY ...

That would help to migrate to PostgreSQL for DB engines having a different default behavior regarding NULL sorting.

Thanks!
Seb
