Doctrine Query Builder not working with UPDATE and INNER JOIN

Question

In my repository I have this query:

$qb = $this->getEntityManager()->createQueryBuilder();
$qb
    ->update('MyBundle:Entity1', 'e1') 
    ->join('e1.Entity2', 'e2')
    ->set('e1.visibile', '1')
    ->andWhere('e2.id = :id')->setParameter("id", 123)
;

throw this error

[Semantical Error] line 0, col 66 near 'e2.id = :id': Error: 'e2' is not defined

I have checked the relation and it is right. Is there any issue using join in query update?

Answer 1

You can not use join on update and delete queries. You have to use subqueries.

Joins are not supported on update and delete queries because it is not supported on all dbms. It won't be implemented in Doctrine 1 or Doctrine 2. You can however get the same affect by using subqueries.

If you are using MySQL, using subqueries will not work. You will have then to use 2 queries.

In MySQL, you cannot modify a table and select from the same table in a subquery
