You can't get the same with a left join (users fields will be repeated over and over) and you can't get the same with 2 separated statements since they will need 2 connections. But from the client side, suppose it PHP... if the first statement return no record and the second one return 3 records, how can I know? What about functions like pg_num_fields? -- Ivan Sergio Borgonovo http://www.webthatworks.it -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
