분리자를 이용하면 좀 더 예쁘게 볼 수 있다.

만일 group_concat의 결과가 BLOB으로만 보인다면,
아래와 같이 변경해서 출력하면 된다.
기존 : group_concat( 필드명 )
변경 : group_concat(cast( 필드명 as char) )

PostgreSQL では、集約関数を自分で定義できたりします。
これを作ってしまうと、
SELECT id, SUM(point) FROM Points GROUP BY id
みたいなノリで「カンマで文字列を結合する」集約処理
SELECT id, comma_join(point_name) FROM Points GROUP BY id
みたいなことができちゃいます。
では早速。
CREATE FUNCTION text_comma_join(text, text) RETURNS text AS 'SELECT $1 || '','' || $2
' LANGUAGE SQL;
CREATE FUNCTION skip_initial(text) RETURNS text AS '
SELECT substr($1, 2)
' LANGUAGE SQL;
CREATE AGGREGATE comma_join (
BASETYPE = text,
SFUNC = text_comma_join,
STYPE = text,
FINALFUNC = skip_initial,
INITCOND = ''
);
