Is there possible to use createQueryBuilder for insert/update? If not, what function should I use?

Question

For now I succeded to create a function that retrieves data from the database using Doctrine's function createQueryBuilder.

Does anybody know if there is a similar function to insert or update the database? Or how can i use createQueryBuilder?

Doctrine 2 ORM does not support INSERT via DQL or the DQL query builder. For a complete syntax, check the EBNF of DQL.

To handle inserts in ORM, you always manually instantiate an entity and persist it with the entity manager:

$user = new \My\Entity\User();

$entityManager->persist($user);
$entityManager->flush();

You can only handle SELECT, UPDATE and DELETE via DQL in Doctrine ORM:

• Select:

  SELECT u FROM My\Entity\User u WHERE u.id = :userId
  

• Update:

  UPDATE My\Entity\User u SET u.status = 'banned' WHERE u.id = :userId
  

• Delete

  DELETE My\Entity\User u WHERE u.id = :userId
  

You can handle these operations with the QueryBuilder as well:

• Select:

    $queryBuilder = $entityManager->createQueryBuilder();
    $queryBuilder
        ->select('u')
        ->from('My\Entity\User', 'u')
        ->where($queryBuilder->expr()->eq('u.id', ':userId'));

• Delete:

    $queryBuilder = $entityManager->createQueryBuilder();
    $queryBuilder
        ->delete('My\Entity\User', 'u')
        ->where($queryBuilder->expr()->eq('u.id', ':userId'));

• Update:

    $queryBuilder = $entityManager->createQueryBuilder();
    $queryBuilder
        ->update('My\Entity\User', 'u')
        ->set('u.status', 'banned')
        ->where($queryBuilder->expr()->eq('u.id', ':userId'));
