Где запрос + Доктрина

Question

У меня есть таблица item с item_id, item_title, item_description, item_created, item_approved. У меня также есть таблица article с PK item_id (из таблицы товаров) и article_body.

Теперь я хотел бы выбрать все статьи, где item.item_approved НЕ равно NULL. Но я застрял в создании запроса. Это то, что я сейчас:

$entityManager = $this->getDoctrine()->getManager(); 
$repository = $entityManager->getRepository('VolleyScoutBundle:Article'); 

$query = $repository->createQueryBuilder('a') 
    ->where('a.item.ItemApproved != NULL') 
    ->getQuery(); 

$articles = $query->getResult(); 

Это дало мне ошибку: [Syntax Error] line 0, col 73: Error: Expected =, <, <=, <>, >, >=, !=, got '.'

Это моя статья Entity:

<?php 

namespace VolleyScout\VolleyScoutBundle\Entity; 

use Doctrine\ORM\Mapping as ORM; 

/** 
* Article 
* 
* @ORM\Table(name="article") 
* @ORM\Entity

class Article 
{ 
    /**

    private $articleBody;

Answer 1

:

$query = $repository->createQueryBuilder('a') 
->join('a.item', 'i') 
->where('i.ItemApproved is not NULL') 
->getQuery();
