Re: Can we return a table from a function?

Perhaps the original question is asking for cursors:

CREATE OR REPLACE FUNCTION
get_data( refcursor, character varying, character varying, varying)
RETURNS refcursor AS'
DECLARE
_arg1_ ALIAS FOR $2;
_arg2_ ALIAS FOR $3;
selectstring TEXT;
BEGIN
selectstring := 'SELECT foo FROM bar
WHERE col1=_arg1_ AND col2=_arg2_';
RAISE NOTICE ''%'', selectstring;
OPEN $1 FOR EXECUTE selectstring;
RETURN $1;
END;
' LANGUAGE plpgsql;
