Mysql innerjoin上未知的关系别名

这是我的数据库：

当我尝试使用mysql时，这个查询一切正常：

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);

但给了我一个错误：

Unknown relation alias 

这是我的YAML文件：

怎么了？ 谢谢。

应该是->内部加入'p.id=r.idPrivato'p.richestepreventivo as r ON p.id=r.idPrivato'

更新：尝试

我有一些工作代码，做几乎相同的，没有作为在它。为了以防万一，请检查生成的模型类，DQL区分大小写。从您的YAML中可以清楚地看出，它们应该是小写的，但可能有人重命名了它们。

可能重复no，您发布的内容是关于加入mysql而不带条令。对于您的更新查询，我返回了：未知关系别名richiestepreventivo…..richiestepreventivo是一个表，而不是一个私有字段如果您很好奇为什么这些查询在应该有的时候不起作用，在这两段代码中，您的reliation别名的名称末尾都有一个拼写错误，即缺少“es”。我想你在寻找：'>innerJoin'p.RichiestepPreventivoes r'这应该是可以接受的答案。最好在不指定连接条件的情况下引用别名，除非执行多个条件，并让条令在幕后处理它。

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

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