Doctrine query syntax error in multiple join

问题

I'm trying to query the model in my Symfony2 project, and I have a little problem that I can't figure out. Check this out:

$q2 = 
  'SELECT 
    p.code, 
    p.desc, 
    SUM(d.quantity) as quantity, 
    SUM(d.quantity*d.prize) as euros
  FROM 
    Product p 
  JOIN 
    TransactionDetail d
  JOIN 
    d.transaction t
  WHERE 
    d.product IN :array 
  AND 
    t.shop = :shop
  GROUP BY 
    p.code';
$query2 = $this->em->createQuery($q2)
  ->setParameter('shop', $shop)->setParameter('array', $array);
$result = $query2->getResult();

And I get this error:

[Syntax Error] line 0, col 248: Error: Expected =, <, <=, <>, >, >=, !=, got 't'

I don't understand it. Can anyone help me here?

Thanks.

I think you should link TransactionDetail with another entity :

Currently :

JOIN 
    TransactionDetail d

Should be:

JOIN 
    p.transactionDetail d
