如何在Symfony默认查询构建器中添加列

$queryBuilder->select('name', 'email');

use Doctrine\ORM\EntityManagerInterface;

class YourController
{
    private $entityManager;

    public function __construct(EntityManagerInterface $entityManager)
    {
        $this->entityManager = $entityManager;
    }

    public function yourAction()
    {
        $queryBuilder = $this->entityManager->createQueryBuilder();

        $queryBuilder->select('name', 'email')
            ->from('YourEntity', 'e')
            ->where('e.someField = :value')
            ->setParameter('value', 'some value')
            ->orderBy('e.name', 'ASC');

        $result = $queryBuilder->getQuery()->getResult();

        // 处理查询结果...
    }
}
