Question

我想根据e.rules_id创建一个恢复号码的请求，e.status_id

public function findStat() 
{
 $types = $this->em
        ->getRepository('EthanRestBundle:EthanRules')
        ->createQueryBuilder('e')
        ->select('e.rules_id, e.status_id, COUNT(*)')
        ->groupBy('e.rules_id, e.status_id')
        ->orderBy('rules_id');

    $types = $types->getQuery()->getSingleScalarResult();

    return $types;

}

错误消息：

[语义错误]第0行，第9行附近＆＃39; rules_id，e.status_id，＆＃39;：错误：类Ethan \ RestBundle \ Entity \ EthanRules没有名为rules_id的字段或关联＆＃34;

我使用FosrestBundle在Symfony 2上开发以创建REST应用程序

Answer 1

默认情况下，Doctrine在实体类中使用camelCase命名所有字段，但在数据库中使用with_underscores命名。

您需要相应地将rules_id和status_id更改为rules和status。

Answer 3

由于您尚未定义属性$rules_id，因此不能选择一个属性。而是加入两个实体并选择它们的ID：

$types = $this->em
    ->getRepository('EthanRestBundle:EthanRules')
    ->createQueryBuilder('e')
    ->select('r.id AS rule_id, s.id AS status_id, COUNT(DISTINCT e.id)')
    ->leftJoin('e.rules', 'r')
    ->leftJoin('e.status', 's')
    ->groupBy('r.id, s.id')
    ->orderBy('r.id');

但是：您使用的getSingleScalarResult()不适用于多个结果行！对你来说，getArrayResult()是最好的选择，因为看起来你不想使用对象。

实体类没有像我的数据库中那样命名的字段或关联
