Specify table name using namespace in createQuery in Doctrine

Question

I need to create a database query in a table whose name is order and that cannot be changed. I made the following query:

$query = $entityManager->createQuery("SELECT sum(o.orderPrice) 
                                            FROM  \App\Entity\Order  o 
                                            WHERE o.orderEventId = ?1
                                                  o.orderDate <= ?2
                                                  o.orderDate >= ?3")
                            ->setParameters(array(
                                                    1 => $event,
                                                    2 => ' LAST_DAY(CURDATE()) ',
                                                    3 => ' DATE_SUB(LAST_DAY(NOW()), INTERVAL DAY(LAST_DAY(NOW()))-1 DAY)'
                                                 )
                                            );


    $dados['qtd_resultado'] = $query->getResult();

The App Entity Order namespace indicated in FROM points to the following Entity in Doctrine:

namespace App\Entity;

use Doctrine ORM Mapping Entity;

/**
 * @Entity
 * @Table(name="order")
 */
class Order
{
}

The problem occurs in FROM because the word ORDER is reserved, so when mounting the query the system presents syntax error. What is the correct way to enter the table name?
