Subject: infinite loop in an update statement
Date: Mon, 9 Sep 2024 16:55:01 +0200

Hi,

table a and b are empty, this query does not return. It seems we enter in
infinite loop.
why this update does not return instantly?

UPDATE table_a a
 SET col1 = (SELECT MIN(b.col1)
                    FROM table_b b
                    WHERE b.col2 = a.col2)

Regards,

Fabrice
