symfonyのクエリ結果は、動作中のクエリ（DBからの結果を含むクエリ）の空の文字列を返します。

Question

私のアプリケーションのカスタム検索クエリを構築しています。問題はクエリの結果が空であることですが、私はphpMyAdminで同じクエリ（デバッグから実行可能なクエリ）を実行すると、私は期待される結果を得ました。

は、問題がどこにあるsomeoenが知ってい：

class ProductRepository extends EntityRepository 
{ 
    public function findByParameters($searchParameters) 
    { 
     $condition = $this->createQueryBuilder('p') 
     ->where('p.state LIKE :state') 
     ->setParameter('state', 0); 
     if(isset ($searchParameters["title"])){ 
     $condition 
      ->andWhere('p.title LIKE :title') 
      ->setParameter('title', $searchParameters["title"]); 
     } 
     if(isset ($searchParameters["categories"])){ 
     $condition 
      ->andWhere('p.categories IN (:categories)') 
      ->setParameter('categories', $searchParameters["categories"]); 
     } 
     if(isset ($searchParameters["productCondition"])){ 
     $condition 
      ->andWhere('p.productCondition = :productCondition') 
      ->setParameter('productCondition', $searchParameters["productCondition"]); 
     } 
     $condition 
     ->getQuery() 
     ->getResult(); 
    return $condition; 
    } 
} 

symfonyのデバッグ教義ログ：

SELECT t0.id AS id_1, t0.name AS name_2, t0.surname AS surname_3, t0.username AS username_4, t0.password AS password_5, t0.email AS email_6, t0.created AS created_7, t0.roles AS roles_8 FROM users t0 WHERE t0.id = ?

SELECT 
    t0.id AS id_1, 
    t0.name AS name_2, 
    t0.surname AS surname_3, 
    t0.username AS username_4, 
    t0.password AS password_5, 
    t0.email AS email_6, 
    t0.created AS created_7, 
    t0.roles AS roles_8 
FROM 
    users t0 
WHERE 
    t0.id = ? 
SELECT t0.id AS id_1, t0.name AS name_2, t0.surname AS surname_3, t0.username AS username_4, t0.password AS password_5, t0.email AS email_6, t0.created AS created_7, t0.roles AS roles_8 FROM users t0 WHERE t0.id = 5; 

EDIT：

これが実行可能である。ここ

コードですsymfonyデバッグからのクエリですphpMyAdminの中で働い：

SELECT p0_.id AS id_0, p0_.state AS state_1, p0_.title AS title_2, p0_.content AS content_3, p0_.price AS price_4, p0_.images AS images_5, p0_.created_at AS created_at_6, p0_.updated_at AS updated_at_7, p0_.expires_at AS expires_at_8, p0_.condition_id AS condition_id_9, p0_.user_id AS user_id_10 FROM product p0_ WHERE p0_.state LIKE 0 AND p0_.title LIKE 'Pc'; 

UPDATE：

I checked Doctrine logs and I am getting this error too: 

AppBundle\Entity\Product  
The association AppBundle\Entity\Product#productCondition refers to the inverse side field AppBundle\Entity\ProductCondition#products which does not exist. 
The association AppBundle\Entity\Product#user refers to the inverse side field AppBundle\Entity\User#products which does not exist.

あなたはここに言及したデバッグクエリは、実際の教義のクエリと一致していません。 Symfony profiler> Doctrineに行くと、クエリのリストがあります。

あなたの教義と一致するものを見つけてphpmyadminで実行したり、ここに貼り付けることができれば、問題を見つけるのが役に立ちます。
