從原材料MySQL查詢symfony的2

Question

我試着使用此查詢來獲取一個Symfony2的實體：

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 

到目前爲止，我有這樣的：

$query = $giftRepository->createQueryBuilder('p') 
    ->where(':now >= p.validbegin AND :now <= p.validend') 
    ->setParameter('now', new \DateTime()) 
    ->orderBy('p.points', $hts) 
    ->getQuery(); 
    $gifts = $query->getResult(); 

它的工作，但不完整的，我不知道我怎麼能在查詢內部調用第二個表（giftcode），就像我在原始查詢中所做的一樣。

Answer 1

你可以嘗試這樣的：

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

現在，你可以通過$list迭代環節都將是一個Gift。

知道有多少Giftcodes沒有一個Gift擁有，你唯一需要做的：

$qtty= count($gift->getCodes());
