doctrine unknow relation alias on innerjoin

this is my database:

When I try with mysql this query all goes good:

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

But If I do:

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

But gives me this error:

Unknown relation alias

What is wrong? Thanks.

It should be ->innerJoin('p.richiestepreventivo as r ON p.id=r.idPrivato ')

UPDATE: try

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

I have some working code that do almost the same and there is no as in it. And, just in case, please check your generated model classes, DQL is case-sensitive. From your YAML it is clear they should be lowercase, but maybe somebody renamed them.

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