[GENERAL] IF ROW( NEW ) ROW( OLD )
Is it possible to cast a table type to a ROW so that Row-Wise comparison can be achieved? -- Regards, Richard Broersma Jr. Visit the Los Angles PostgreSQL Users Group (LAPUG) http://pugs.postgresql.org/lapug -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

However, I was under the impression that table types were essentially composite types. So I thought that composite types would behave the same. I could manually expand the composite type OLD and NEW to enumerate each field and make a row wise comparison. However, I was hoping to avoid that. -- Regards, Richard Broersma Jr. Visit the Los Angles PostgreSQL Users Group (LAPUG) http://pugs.postgresql.org/lapug -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
