我想创建一个根据e.rules_id、e.status_id 恢复数字的请求
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列，靠近'rules_id，e.status_id，'：错误：类Ethan''RestBundle''Entity''EthanRules没有名为rules_id"
我使用FosrestBundle在Symfony 2上进行开发，以创建REST应用程序

由于您尚未定义属性$rules_id原则无法选择属性。相反，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()无法处理多个结果行！getArrayResult()无疑是您的最佳选择，因为看起来您不想使用对象。
您需要相应地将rules_id和status_id更改为rules和status。
