How can I select specific Columns with createQueryBuilder in Doctrine ORM?

I'm using Doctrine createQueryBuilder() to construct queries in Symfony2. But, I don't want to take all columns in this entity. How can I select only the ID and Name?

$query = $this->getEntityManager()->createQueryBuilder();
        $query
            ->select('d')
            ->from('AcmeBundle:Demo', 'd')
            ->leftjoin('d.otherEntity', 'o');

        $query->setMaxResults(10);
        $results = $query->getQuery()->getResult();

Thank you so much,

Try following,

$fields = array('d.id', 'd.name', 'o.id');
//$fields = 'partial d.{id, name}, partial o.{id}';  //if you want to get entity object

$query = $this->getEntityManager()->createQueryBuilder();
$query
    ->select($fields)
    ->from('AcmeBundle:Demo', 'd')
    ->leftjoin('d.otherEntity', 'o');

$query->setMaxResults(10);
$results = $query->getQuery()->getResult();
