更新Doctrine中的总关系计数器

Question

愚蠢的问题，但我无法找到答案。

我需要执行这样的查询：

    # Disable Code Coverage for Pods projects except MyPod
    post_install do |installer_representation|
      installer_representation.pods_project.targets.each do |target|
        if target.name == 'MyPod'
          target.build_configurations.each do |config|
            config.build_settings['CLANG_ENABLE_CODE_COVERAGE'] = 'YES'
          end
        else 
          target.build_configurations.each do |config|
            config.build_settings['CLANG_ENABLE_CODE_COVERAGE'] = 'NO'
          end
        end
      end
    end

或通过hibernate.jdbc.batch_size=50

$em
    ->createQueryBuilder()
    ->update('AppBundle:Contest\Member', 'm')
    ->innerJoin('m.votes', 'v')
    ->set('m.total_votes', 'COUNT(v.id)')
    ->where('m.id = :member')
    ->setParameter('member', $member->id())
    ->getQuery()
    ->execute()
;

Doctrine断然拒绝执行查询。

我做错了什么？

我找到了解决方案

$total = $em
    ->getRepository('AppBundle:Contest\Member\Vote')
    ->createQueryBuilder('v')
    ->select('COUNT(v.id)')
    ->where('v.member = :member')
    ->setParameter('member', $member->getId())
    ->getDQL()
;

$em->createQueryBuilder()
    ->update('AppBundle:Contest\Member', 'm')
    ->set('m.total_votes', '('.$total.')')
    ->where('m.id = :member')
    ->setParameter('member', $member->getId())
    ->getQuery()
    ->execute()
;
