如何在Doctrine2中使用createQueryBuilder嵌套兩個AND查詢？

Question

以下是我的查詢：

$em = \Zend_Registry::get('em'); 
    $qb_1 = $em->createQueryBuilder(); 
    $q_1 = $qb_1->select('link_req') 
    ->from('\Entities\link_requests','link_req') 
    ->where('link_req.is_confirmed = 1') 
    ->andWhere('link_req.$link_requestsSenderUser='.$user1_id .'or'.' link_req.$link_requestsSenderUser='.$user2_id) 
    ->andWhere('link_req.$link_requestsReceiverUser='.$user1_id .'or'.' link_req.$link_requestsReceiverUser='.$user2_id); 
    $result= $q_1->getDql(); 
    echo $result; 

，我想下面的查詢：

SELECT * FROM [fb_local].[dbo].[link_requests] 
WHERE is_confirmed = 1 AND (request_user_id = 12 or request_user_id=19) AND (accept_user_id = 12 or accept_user_id = 19)

你的SQL只是1查詢，所以不知道你想什麼窩。但是，請嘗試以下操作：我

$em = \Zend_Registry::get('em'); 
    $qb_1 = $em->createQueryBuilder(); 
    $q_1 = $qb_1->select('link_req') 
     ->from('\Entities\link_requests','link_req') 
     ->where('link_req.is_confirmed = 1') 
     ->andWhere('link_req.link_requestsSenderUser=:user_id or link_req.link_requestsSenderUser=:user_id') 
     ->andWhere('link_req.link_requestsReceiverUser=:user_id or link_req.link_requestsReceiverUser=:user_id'); 
    $q_1->setParameter('user_id', $user1_id); 
    $query = $q_1->getQuery(); 
    echo $query->getSql(); 

注意如何在link_requestsReceiverUser前取出$。我也從$user1_id發了一個參數，這可以防止SQL injections。
