Where query + Doctrine - php

Question

I have table item with item_id, item_title, item_description, item_created, item_approved. I also have a table article with PK item_id (from item table) and article_body.
Now I would like to select all the articles where item.item_approved is NOT equal to NULL. But I'm stuck with creating the query. This is what I have now:
$entityManager = $this->getDoctrine()->getManager();
$repository = $entityManager->getRepository('VolleyScoutBundle:Article');
$query = $repository->createQueryBuilder('a')
->where('a.item.ItemApproved != NULL')
->getQuery();
$articles = $query->getResult();
This gave me the error: [Syntax Error] line 0, col 73: Error: Expected =, <, <=, <>, >, >=, !=, got '.'
This is my Article Entity:
<?php
namespace VolleyScout\VolleyScoutBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Article
*
* #ORM\Table(name="article")
* #ORM\Entity
*/
class Article
{
/**
* #var string
*
* #ORM\Column(name="article_body", type="text", nullable=false)
*/
private $articleBody;
/**

*
* #ORM\Id
* #ORM\GeneratedValue(strategy="NONE")
* #ORM\OneToOne(targetEntity="VolleyScout\VolleyScoutBundle\Entity\Item")

* })
*/
private $item;
/**

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