createtime, CONCAT(UPPER(customers.lastname), ' ', customers.name) AS
customername, userid, users.name AS username, customerid FROM rtmessages
LEFT JOIN customers ON (customers.id = customerid) LEFT JOIN users ON
(users.id = userid) WHERE ticketid = '667') UNION (SELECT rtnotes.id AS
id, NULL, NULL, body, createtime, NULL, userid, users.name AS username,
NULL FROM rtnotes LEFT JOIN users ON (users.id = userid) WHERE ticketid
