zendフレームワークで以下のクエリを実行したい。誰かが私にそれをどのように行うことができるか教えてもらえますか？

(SELECT `msg`.`message_sender_id`, `msg`.`message_receiver_id`, `msg`.`message_content`, `msg`.`message_sent_on`, `usr`.`user_name` AS `sender_name`
 FROM `sc_message` AS `msg` INNER JOIN `sc_user` AS `usr` ON `msg`.`message_sender_id` = `usr`.`user_id` 
 WHERE `msg`.`message_id` = 3 ORDER BY `msg`.`message_sent_on`)

UNION 

(SELECT `msg_slv`.`message_slave_sender_id`, `msg_slv`.`message_slave_receiver_id`, `msg_slv`.`message_slave_content`, `msg_slv`.`message_slave_sent_on`, `usr`.`user_name` AS `sender_name`
 FROM `sc_message_slave` AS `msg_slv` INNER JOIN `sc_user` AS `usr` ON `msg_slv`.`message_slave_sender_id` = `usr`.`user_id`
 WHERE `msg_slv`.`message_id` = 3 ORDER BY `msg_slv`.`message_slave_sent_on`)

私は以下のコードを書きました

    $Query_1 = $this ->select()
                     ->from(array('msg' => 'sc_message'), array('msg.message_sender_id', 'msg.message_receiver_id', 'msg.message_content', 'msg.message_sent_on'))
                     ->joinInner(array('usr' => 'sc_user'), 'msg.message_sender_id = usr.user_id', array('usr.user_name as sender_name'))
                     ->where('msg.message_id = ?',$message_id)
                     ->setIntegrityCheck(false);

    $this->_name = "sc_message_slave";
    $this->_primary = "message_slave_id";
    $Query_2 = $this ->select()
                     ->from(array('msg_slv' => 'sc_message_slave'), array('msg_slv.message_slave_sender_id', 'msg_slv.message_slave_receiver_id','msg_slv.message_slave_content', 'msg_slv.message_slave_sent_on'))
                     ->joinInner(array('usr' => 'sc_user'), 'msg_slv.message_slave_sender_id = usr.user_id', array('usr.user_name as sender_name'))
                     ->where('msg_slv.message_id = ?',$message_id)
                     ->setIntegrityCheck(false);

Zend_Db_Table メソッドで作業しているとします。

//your code...

$unionSelect = $this->getAdapter()->select()->union(array($Query_1, $Query_2));
//no you can execute it
$rows = $this->getAdapter()->fetchAll($unionSelect);
