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
到目前为止，我有这个：
$query = $giftRepository->createQueryBuilder('p')
->where(':now >= p.validbegin AND :now <= p.validend')
->setParameter('now', new \DateTime())
->orderBy('p.points', $hts)
->getQuery();
$gifts = $query->getResult();
它工作但不完整，我不知道如何在查询中调用第二个表（giftcode），就像我在原始查询中所做的那样。
