Symfony1 Symfony内连接

如何在symfony中编写内部连接查询

$tagQuery = Doctrine_Query::create()
            ->from('SfTagging t')
            ->innerjoin('t.Link L ON t.taggable_id=L.id');

echo $tagQuery->getSqlQuery();

您不需要指定ON-part，如果您的模式不太糟糕，则条令已经知道如何进行连接。我会这样写：

$tagQuery = SfTaggingTable::getInstance()
  ->createQuery('t')
    ->innerJoin('t.Link');
echo $tagQuery->getSqlQuery();

$tagQuery = Doctrine_Query::create()    
  ->from('SfTagging t')
  ->innerJoin('t.Link l');
echo $tagQuery->getSqlQuery();
