For this I have used the following query in Doctrine2: public function findCourse() { return $this->getEntityManager()-

Doctrine DQL Delete from relation table

由 不问归期 提交于 2019-12-10 16:13:21
问题 Using Doctrine 2 and Symfony 2.0. I have two Doctrine entities (let's suppose EntityA and EntityB). I have a ManyToMany relation between them. So a EntityA_EntityB table has been created in database. Using DQL or QueryBuilder, how can I delete from that relation table EntityA_EntityB? Docrtine offers something like this to perform something similar: ->delete() ->from('EntityA a') ->where('a.id', '?', $id); But I don't really get how to perform the deletion of row from the relation table. 回答1:

Get random records with Doctrine

由 我们两清 提交于 2019-12-10 02:12:08
问题 I wonder how to get a random number of Members from a Group, but I do not know what is the best way to do this, and I think ORDER BY RAND() is not the best alternative, as a Group can have more than 100,000 Members, performing this type of query could be very slow.

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
