-----Original Message----- And why can't I add u.name, u.avatar to fetch all the info I need in 1 pass? # select r.id, count(r.id), u.name, u.avatar, u.city from pref_rep r, pref_users u where r.nice=true and to_char(current_timestamp - interval '1 month', 'IYYY-MM') = to_char(r.last_rated, 'IYYY-MM') and u.female=true and r.id=u.id group by r.id order by count desc limit 7; ERROR: column "u.*" must appear in the GROUP BY clause or be used in an aggregate function LINE 1: select r.id, count(r.id), u.name, u.avatar, u.city ^ Is there a way to workaround it? >>>>>>>>>>>>>>>>>>>> I believe you need to put 'name' in quotes ( like u."name" ) The fact that the warning indicates "u.*" where you didn't use "u.*" anywhere in your literal syntax means that PostgreSQL is interpreting something funny. Trial and error should have narrowed down the options if you didn't catch that "name" is so common as to likely be utilized by the database. Going from memory here...
