dql

Can someone provide me a couple clear (fact supported) reasons to use/learn DQL vs. SQL when needing a custom query while working with Doctrine Classes? I find that if I cannot use an ORM's built-in relational functionality to achieve something I usually write a custom method in the extended Doctrine or DoctrineTable class. In this method write the needed it in straight SQL (using PDO with proper prepared statements/injection protection, etc...). DQL seems like additional language to learn/debug/maintain that doesn't appear provide enough compelling reasons to use under most common situations.

I'm probably overlooking something very simple and just been staring at it too much, but I can't get this DQL query to work. I get an exception stating: Cannot select entity through identification variables without choosing at least one root entity alias. Here's my query. User has a many-to-one relation to Group. Note that this is a unidirectional relation! That may make no sense to you, but it makes sense in our domain logic. SELECT DISTINCT g FROM Entity\User u LEFT JOIN u.group g WHERE u.active = :active Can you tell me what I am missing here? Since this is the first Google match when

I am trying to use the DATE_ADD function from doctrine2 but I am having trouble get it right. I am using like this in DQL: ->andWhere('p.created_at <= DATE_ADD(CURRENT_DATE(),4, day)') but I am getting syntax error: [Syntax Error] line 0, col 215: Error: Expected'.' or '(', got 'day' I tried different implementations but I allways get some kind of syntax errror. I have checked DoctrineExtensions which contain this function, but I shouldnt need it because the function is already included in doctrine. You have a typo, you have to quotes 'day' ->andWhere("p.created_at <= DATE_ADD(CURRENT_DATE(),4

How can I select all items from one specific author ? Its possible this way ? Or how can I edit entities if I want many item types and item packages (item has many items) too ? Item /** * @ORM\Table() * @ORM\Entity * @ORM\InheritanceType("JOINED") * @ORM\DiscriminatorColumn(name="discr", type="string") * @ORM\DiscriminatorMap({ * "cd" = "ItemCD", * "dvd" = "ItemDVD", * "pack" = "ItemPack", * }) */ class Item { /** * @ORM\Column(name="id", type="integer", nullable=false) * @ORM\Id * @ORM\GeneratedValue(strategy="IDENTITY") */ private $id; /** * @ORM\Column(name="name", type="string", length=250

I'm trying to use external params in a DQL-s SELECT part, but it doesn't work due to an error. What I'm trying: $query = $this->getEntityManager() ->createQuery(" SELECT me.column_one, :param_doesnt_work param FROM CompanyMyBundle:MyEntity me WHERE me.column_one = :param_one AND me.column_two = :param_two ")->setParameters(array( 'param_doesnt_work' => 'A static value', 'param_one' => 'some param', 'param_two' => 'another param', )); I would like to get two columns as a result, the value of 'column_one' and the value of the param in the Select ('A static value' in this case As param). I get

Doctrine 2 has the Doctrine\ORM\Tools\Pagination\Paginator class which can be used to paginate normal DQL queries. However if I pass it a native query, I get this error: Catchable fatal error: Argument 1 passed to Doctrine\ORM\Tools\Pagination\Paginator::cloneQuery() must be an instance of Doctrine\ORM\Query, instance of Doctrine\ORM\NativeQuery given I've tried removing the type-hinting from the paginator class in the cloneQuery method, but this just gives further errors because other bits of the paginator class expect methods found in Query that aren't in NativeQuery. Is there any easy way

How should I go about ordering by a discriminator column in a doctrine repository query? I have a pretty straight forward setup, I have different types of payment details, it can either be Credit Card (CC) or Debit Order (DO). So I've implemented a single table inheritance mapping strategy to achieve this, but the problem now comes in when I try to order by the discriminator column, since the discriminator column isn't present in the base class. The repository function: public function getPaymentDetails (ClientContactInterface $clientContact) { $dql = 'SELECT pd from AccountingBundle
