Propel and leftJoin

2019-06-25 00:08发布

In Doctrine i can:

    $q = Doctrine_Query::create()
        ->from('One o')
        ->where('t.text = ?', 'aaa')
        ->andWhere('h.text = ?', 'bbb')
        ->leftJoin('o.Two t')
        ->leftJoin('t.Three h')
        ->leftJoin('h.Four f')
        ->execute();

How can i make this in Propel from Symfony 1?

If you use propel before 1.6, you have to follow

You have to know the primary key for each relation. If it's id, it can be something like that:

$c = new Criteria();

$c->add(TwoPeer::TEXT, 'aaa');
$c->add(ThreePeer::TEXT, 'bbb');

$c->addJoin(OnePeer::TWO_ID, TwoPeer::ID, Criteria::LEFT_JOIN);
$c->addJoin(TwoPeer::THREE_ID, ThreePeer::ID, Criteria::LEFT_JOIN);
$c->addJoin(ThreePeer::FOUR_ID, FourPeer::ID, Criteria::LEFT_JOIN);

$results = OnePeer::doSelect($c);

For Propel 1.6 (use it from https://github.com/propelorm/sfPropelORMPlugin), something like that:

$results = OneQuery::create()
  ->useTwoQuery()
    ->filterByText('aaa')
    ->useThreeQuery()
      ->filterByText('bbb')
    ->endUse()
  ->endUse()
  ->leftJoinWith('Three.Four')
  ->find();

In relation to j0k answer, an easier way would be:

$results = OneQuery::create()
   ->useTwoQuery(null, Criteria::LEFT_JOIN)
      ->filterByText('aaa')
      ->useThreeQuery(null, Criteria::LEFT_JOIN)
         ->filterByText('bbb')
      ->endUse()
   ->endUse()
->find();
