In recent PostgreSQL versions I believe this is properly written: update certgroups c set termgroupname = tg.termgroupname from termgroup tg where (c.days >= tg.mindays) and (c.days <= tg.maxdays); At least as of SQL2003, I think both of the above use extensions, so there's no guarantee to the behavior on different systems and to do it with a standard query, you'd need to use a subselect, something like: update certgroups c set termgroupname = (select termgroupname from termgroup tg where (c.days >= tg.mindays) and (c.days <=tg.maxdays)); -- Sent via pgsql-sql mailing list (pgsql-sql@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-sql
