I am new in Symfony framework And I want to use Query basis on Condition
which is using associative array and I want to use IS NOT NULL But it is not
working.
$repository = $this->getDoctrine()->getRepository('AppBundle:Order');
$order = $repository->findBy(array('status' => $last_status,'new_coloumn_id'=>"IS NOT NULL"));
How to use IS NOT NULL in array.
