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

I know this is an old question. But I used the following solution to get the random row.

Using an EntityRepository method:

public function findOneRandom()
{
    $id_limits = $this->createQueryBuilder('entity')
        ->select('MIN(entity.id)', 'MAX(entity.id)')
        ->getQuery()
        ->getOneOrNullResult();
    $random_possible_id = rand($id_limits[1], $id_limits[2]);

    return $this->createQueryBuilder('entity')
        ->where('entity.id >= :random_id')
        ->setParameter('random_id', $random_possible_id)
        ->setMaxResults(1)
        ->getQuery()
        ->getOneOrNullResult();
}
