I'd like to make a function with this SQL:
CREATE FUNCTION kodok.group_users(group_name "varchar")
RETURNS SETOF "varchar" AS
$BODY$
SELECT pg_user.usename
FROM pg_user, pg_group
WHERE usesysid = any (pg_group.grolist) AND pg_group.groname=$1;
$BODY$
LANGUAGE 'sql' VOLATILE;
But I get the next error message:
ERROR: return type mismatch in function declared to return character
varying
DETAIL: Actual return type is name.
CONTEXT: SQL function "group_users"
At the moment, I don't understand what is the problem, and what I need
to do now...?
Thanks,
kjt
