The following bug has been logged online: Bug reference: 5385 Logged by: Corin Email address: wakath...@gmail.com PostgreSQL version: 8.4.2 Operating system: ubuntu amd64 Description: gd disallows agg function in subselect of update Details:
query: UPDATE imagecontest_participations AS g SET rating_ratings_sum=(SELECT SUM(rating_ratings_sum) FROM imagecontest_participation_ratings WHERE imagecontest_participation_id=g.id) error message: cannot use aggregate function in UPDATE while looking for a solution I found this commit: http://archives.postgresql.org/pgsql-committers/2006-06/msg00299.php ... "Disallow aggregate functions in UPDATE commands (unless within a sub-SELECT). This is disallowed by the SQL spec because it doesn't have any very sensible interpretation." ... As the subquery is not top-level but inside a subquery I suspect this being an error. I don't want to use the UPDATE ... FROM syntax if possible to keep compatibility with other sql servers. -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs
