Hello, I have following problem with PostgreSQL 6.5.3, I haven't possiblity to check it on 7.0 and I want to know is it possible to run such query: SELECT k.pic, id_g, id_k, count(*) FROM kart k, pictues p WHERE k.pic = p.pic GROUP BY k.pic PICTURES(pic,id_g,id_k) KART (pic,email,mess,date) I've got answer from Postgres "Illegal attributes or non-group column" Is it error in query or in parser ? Yours Jan Bajerski
