How to select randomly with doctrine

Question

Here is how I query my database for some words

$query = $qb->select(\'w\')
    ->from(\'DbEntities\\Entity\\Word\', \'w\')
    ->where(\'w.indiction         


        

Answer 1

I hope this would help others:

        $limit = $editForm->get('numberOfQuestions')->getData();
        $sql = "Select * from question order by RAND() limit $limit";

        $statement = $em->getConnection()->prepare($sql);
        $statement->execute();
        $questions = $statement->fetchAll();

Note here the table question is an AppBundle:Question Entity. Change the details accordingly. The number of questions is taken from the edit form, make sure to check the variable for the form builder and use accordingly.
