从原始MySQL查询到symfony 2

我正在尝试使用此查询获取symfony2实体：

SELECT g . *, 
       (SELECT Count(gc.`code`) AS `codecount` 
        FROM   giftcode gc 
        WHERE  gc.`gift_id` = g.`id` 
               AND gc.`provided` IS NULL 
        GROUP  BY gc.`gift_id`) AS gcodecount 
FROM   gift g 
WHERE  Now() >= g.validbegin 
       AND Now() <= g.validend 

---

您可以尝试以下方法：

$query=$entityManager->createQuery("SELECT g
                                      FROM gift g  
                                     WHERE  Now() >= g.validbegin 
                                        AND Now() <= g.validend 
                                        AND gc.provided IS NULL");
 $list=$query->getResults();

您的实体是否定义了相应的关系？请您发布您的实体类（礼品和礼品代码）我不处理此实体的实体之间的关系。我只是想知道我是否可以将原始查询直接“翻译”到symfony以获取礼品实体。无论如何，给我30秒，我会添加实体
