Use GROUP BY with an aggregator that concatenate the names. The aggregator may be implemented in plpgsql, for instance: CREATE OR REPLACE FUNCTION concat (text, text) RETURNS text AS 'select case when $1 = '''' then $2 else ($1 || '', '' || $2) end' LANGUAGE sql; CREATE AGGREGATE concat ( BASETYPE = text, SFUNC = public.concat, STYPE = text, INITCOND = '' ); Regards, Manuel. ---------------------------(end of broadcast)--------------------------- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
