查詢生成器生成不正確的查詢

這裏是我的QueryBuilder查詢生成器生成不正確的查詢

     $qb->select('u') 
          ->from(Victim::class,'u') 
          ->join('u.tags','t') 
          ->where('t.id in (11,15)') 
          ->groupBy('u.id') 
          ->having('count(u.id)=2');

它會產生不正確的SQL查詢（看FROM子句）

SELECT 
     v0_.id   AS id_0, 
     v0_.avatarUrl AS avatarurl_1, 
     v0_.displayName AS displayname_2, 
     v0_.summary  AS summary_3, 
     v0_.gender  AS gender_4, 
     v0_.birthDay  AS birthday_5, 
     v0_.maritalState AS maritalstate_6, 
     v0_.folder_id AS folder_id_7 
    FROM victims v1_, victims v0_ 
    INNER JOIN victim_tag v3_ ON v0_.id = v3_.victim_id 
    INNER JOIN tags t2_ ON t2_.id = v3_.tag_id 
    WHERE t2_.id IN (11,15) 
    GROUP BY v0_.id 
    HAVING count(v0_.id) = 2

但是當我使用DQL

     $qry = sprintf(
          'SELECT u FROM %s u JOIN u.%s t WHERE t.id IN (%s) GROUP BY u.id HAVING count(u.id)= %s ORDER BY u.id DESC', 
          Victim::class, 
          $key, 
          implode(',', $value), 
          count($value) 
         );

所得詢問是OK

SELECT 
    v0_.id   AS id_0, 
    v0_.avatarUrl AS avatarurl_1, 
    v0_.displayName AS displayname_2, 
    v0_.summary  AS summary_3, 
    v0_.gender  AS gender_4, 
    v0_.birthDay  AS birthday_5, 
    v0_.maritalState AS maritalstate_6, 
    v0_.folder_id AS folder_id_7 
FROM victims v0_ INNER JOIN victim_tag v2_ ON v0_.id = v2_.victim_id 
    INNER JOIN tags t1_ ON t1_.id = v2_.tag_id 
WHERE t1_.id IN (11, 15) 
GROUP BY v0_.id 
HAVING count(v0_.id) = 2 
ORDER BY v0_.id DESC;

我有點困惑。我想在這裏使用QueryBuilder是因爲它的靈活性，如何使它正常工作？

您是否正在使用RepositoryClass中的查詢生成器？你重寫getAlias（）方法嗎？你可以在課堂上使用洞方法嗎？ –

@ViniciusZaramella否，它是外部存儲庫類，並且Repository類中的任何內容都未被覆蓋。 – sl4mmer

你是如何實現$ qb的？我認爲你可以擦除 - >從（'...）中選擇（'u'） - >並在加入之後保留這些東西。 –

已解決的問題。

$qb->add('select', 'u') 
    ->add('from', Victim::class . ' u') 
    ->join('u.tags','t') 
    ->add('where', 't.id in (11,15)') 
    ->add('groupBy', 'u.id') 
    ->add('having', 'count(u.id)=2');
