Question

我需要将原始查询作为字符串获取，类似这样。

$ query ='SELECT p FROM GabrielUploadBundle：Image p WHERE p.upvotes＆gt; x ORDER BY p.createdAt ASC';

我的自定义“findAllNewestByVotes”方法包含查询。

class ImageRepository extends EntityRepository
{
    public function findAllNewestByVotes($maxvotes)
    {
        return $this->getEntityManager()
        ->createQuery(
            'SELECT p FROM GabrielUploadBundle:Image p WHERE p.upvotes > '.$maxvotes.' ORDER BY p.createdAt ASC')
        ->getResult();
    }

}
/**
 * @Route("/world/front",name="world-front")
 * @Template()
 */
public function indexAction()
{
    $images = $this->get('doctrine')->getRepository('GabrielUploadBundle:Image')->findAllNewestByVotes(50);

    ladybug_dump($images);
    return $this->render('GabrielLayoutBundle:Worldpage:index.html.twig',array('images'=>$images));
}

我需要的是类似的东西 $ images-＆gt; getRawQuery（）//将查询作为字符串返回

解决方案（参考最佳答案）

    /**
     * ImageRepository
     *
     * This class was generated by the Doctrine ORM. Add your own custom
     * repository methods below.
     */
    class ImageRepository extends EntityRepository
    {
        public function findAllNewestByVotes($maxvotes)
        {
            return $this->getEntityManager()
            ->createQuery(
                'SELECT p FROM GabrielUploadBundle:Image p WHERE p.upvotes > '.$maxvotes.' ORDER BY p.createdAt ASC');
        } 
    }

> create image repository

    $images = $this->get('doctrine')->getRepository('GabrielUploadBundle:Image')->findAllNewestByVotes(50);

 return the raw query as string like this

    $images->getDQL()

 return objects like this

    $images->getResult();

可以使用以下方法检索原始查询：

$this->getEntityManager()
    ->createQuery('
        SELECT p
            FROM GabrielUploadBundle:Image p
            WHERE p.upvotes > '.$maxvotes.'
            ORDER BY p.createdAt ASC
    ')
    ->getSQL();

但这是一个简单的查询，为什么不使用DQL并单独添加参数（使用预防SQL注入攻击的预处理语句）？

$this->getEntityManager()
    ->createQueryBuilder()

    ->select('p')
    ->from('GabrielUploadBundle:Image')

    ->where('p.upvotes > :maxvotes')
    ->setParameter('maxvotes', $maxvotes)

    ->orderBy('p.createdAt', 'ASC')

    ->getSQL();

为了能够从控制器获取查询（对象）或查询构建器（对象），您需要将存储库逻辑分解为2个函数，一个构建查询，另一个使用参数调用查询：

class ImageRepository extends EntityRepository
{
    public function findAllNewestByVotesQuery($maxvotes)
    {
        return $this->getEntityManager()
            ->createQueryBuilder()

            ->select('p')
            ->from('GabrielUploadBundle:Image')

            ->where('p.upvotes > :maxvotes')
            ->setParameter('maxvotes', $maxvotes)

            ->orderBy('p.createdAt', 'ASC');
    }

    public function findAllNewestByVotes($maxvotes)
    {
        return $this
            ->findAllNewestByVotesQuery($maxvotes)
            ->getQuery()
            ->getResult();
    }
}
