Why not to use repository?

getRandomProductsNativeQuery($amount)->getResult();
    }

    /**
     * @param int $amount
     * @return ORM\NativeQuery
     */
    public function getRandomProductsNativeQuery($amount = 7)
    {
        # set entity name
        $table = $this->getClassMetadata()
            ->getTableName();

        # create rsm object
        $rsm = new ORM\Query\ResultSetMapping();
        $rsm->addEntityResult($this->getEntityName(), 'p');
        $rsm->addFieldResult('p', 'id', 'id');

        # make query
        return $this->getEntityManager()->createNativeQuery("
            SELECT p.id FROM {$table} p ORDER BY RAND() LIMIT 0, {$amount}
        ", $rsm);
    }
}
