ZF2使用或型號

Question

所以我想實現這個查詢：

SELECT `userMessages`.*, `users`.`username` AS `username` FROM `userMessages` 
INNER JOIN `users` ON `users`.`id` = `userMessages`.`FROMuID` WHERE 
userMessages.FROMuID = 41 AND userMessages.TOuID = 40 
OR userMessages.FROMuID = 40 AND userMessages.TOuID = 41 ORDER BY `userMessages`.`messageTime` DESC 

這裏是我的模型

public function getUserMessages($uID,$fromUID,$paginated = true){ 
    if($paginated) { 
     // create a new Select object for the table ads 
     $select = new Select($this->tableGateway->table); 
     $select->join('users','users.id = userMessages.FROMuID',array('username'),'inner'); 
     $select->where("userMessages.FROMuID = $fromUID"); 
     $select->where("userMessages.TOuID = $uID"); 

     $select->order('userMessages.messageTime DESC'); 
     // create a new result set based on the Ads entity 
     $resultSetPrototype = new ResultSet(); 
     // create a new pagination adapter object 
     $paginatorAdapter = new DbSelect(
      // our configured select object 
      $select, 
      // the adapter to run it against 
      $this->tableGateway->getAdapter() 
      //, 
      // the result set to hydrate 
      //$resultSetPrototype 
      ); 
     $paginator = new Paginator($paginatorAdapter); 
     return $paginator; 
    } 
    $resultSet = $this->tableGateway->select(); 
    return $resultSet; 
} 

你知道我怎麼能做到這一點？我想我需要在我的語句\Zend\Db\Sql\Predicate\中使用，但我不知道如何。

解決由addign下列行：

 $select->where 
      ->equalTo("userMessages.FROMuID",$fromUID) 
      ->equalTo("userMessages.TOuID",$uID) 
     ->or 
      ->equalTo('userMessages.FROMuID', $uID) 
      ->equalTo('userMessages.TOuID', $fromUID);
