Question

我正在尝试使用 Symfony2 createNativeQuery 进行我的第一次加入。

我没有加入第一个，没有问题。

我认为我失去了一些步骤，以便遵循我的代码：

$rsm = new ResultSetMapping;

        $rsm
            ->addEntityResult('Art\ArticleBundle\Entity\ArticleData', 'ad')
//          ->addEntityResult('Art\ArticleBundle\Entity\Article', 'a')
//          ->addFieldResult('ad', 'id', 'article_data_id')
            ->addJoinedEntityResult('Art\ArticleBundle\Entity\Article', 'a', 'ad', 'article')
            ->addFieldResult('a', 'date_article', 'dateArticle');

        $query = $this->_em->createNativeQuery(
            'SELECT ad.id AS article_data_id, ad.title, ad.abstract '
            . 'FROM art_article_data ad '
            . 'INNER JOIN art_article ON (ad.article_id = a.id) '
            ,
            $rsm
        );

        return $query->getResult();

它返回以下错误： SQLSTATE[42S22]: Column not found: 1054 Unknown column 'a.id' in 'on clause'")。

为什么a.id未知？它在实体和表格内。我失去了什么步骤？

正如@Javad所要求的，下面是 Article 实体

Answer 2

您的查询应该是：

$query = $this->_em->createNativeQuery(
        'SELECT ad.id AS article_data_id, ad.title, ad.abstract '
        . 'FROM art_article_data ad '
        . 'INNER JOIN art_article a ON (ad.article_id = a.id) '
        ,
        $rsm
    );

您错过了art_article

的别名
