Question

How do we write an inner join query in symfony?

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

echo $tagQuery->getSqlQuery();

You don’t need to specify the ON part, doctrine already knows how to make the join if your schema is not too bad. I’d write it like this:

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