内连接上的原则未知关系别名

Question

这是我的数据库：

当我尝试使用mysql时，这个查询一切顺利：

SELECT *
FROM privati AS p
INNER JOIN richiestepreventivo AS r
      ON p.id = r.idPrivato
WHERE r.idImpresa = xx

但如果我这样做：

$qr = Doctrine_Query::create()
                ->select('*')
                ->from('privati as p')
                ->innerJoin('richiestepreventivo as r ON p.id=r.idPrivato ')
                ->where('r.idImpresa=' . $idI);

但是给了我这个错误：

Unknown relation alias 

这是我的YAML文件：

有什么问题？ 感谢。

Answer 1

应为->innerJoin('p.richiestepreventivo as r ON p.id=r.idPrivato ')

更新：尝试

$qr = Doctrine_Query::create()
            ->select('*')
            ->from('privati p')
            ->innerJoin('p.richiestepreventivo r ON p.id=r.idPrivato ')
            ->where('r.idImpresa=' . $idI);

我有一些几乎相同的工作代码，其中没有as。而且，为了以防万一，请检查生成的模型类，DQL区分大小写。从你的YAML可以清楚地知道它们应该是小写的，但也许有人将它们重命名。

Answer 2

    $qr = Doctrine_Query::create()
            ->select('r.data_invio,j.*')
            ->from('richiestepreventivo r')
            ->innerJoin('r.idPrivato j');
