我试图把我的第一个连接与Symfony2 createNativeQuery。
我做了第一个没有连接的，没有问题。
我想我丢失了一些步骤，以遵循我的代码:
$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();
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?它位于实体和表中。我漏了哪一步
按照@Javad的要求，下面是Article实体

你的查询应该是:
$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
