Php FOSCommentBundle querybuilder是否添加订单进行错误查询？

我在FOSCommentBundle里有点奇怪

在FOS\CommentBundle\Entity\class CommentManager中扩展了BaseComentManager

方法：

public function findCommentsByThread(ThreadInterface $thread, $depth = null, $sorterAlias = null) 

queryBuilder：

$qb = $this->repository
                ->createQueryBuilder('c')
                ->join('c.thread', 't')
                ->where('t.id = :thread')
                ->orderBy('c.ancestors', 'ASC')
                ->setParameter('thread', $thread->getId());

        if (null !== $depth && $depth >= 0) {
            // Queries for an additional level so templates can determine
            // if the final 'depth' layer has children.

            $qb->andWhere('c.depth < :depth')
               ->setParameter('depth', $depth + 1);
        }

        $comments = $qb
            ->getQuery()
            ->execute();

        print_array([$qb->getQuery()->getSQL(),$comments]);

当我禁用订单时

$qb = $this->repository
                    ->createQueryBuilder('c')
                    ->join('c.thread', 't')
                    ->where('t.id = :thread')
                    //->orderBy('c.ancestors', 'ASC')
                    ->setParameter('thread', $thread->getId());

            if (null !== $depth && $depth >= 0) {
                // Queries for an additional level so templates can determine
                // if the final 'depth' layer has children.

                $qb->andWhere('c.depth < :depth')
                   ->setParameter('depth', $depth + 1);
            }

            $comments = $qb
                ->getQuery()
                ->execute();

            print_array([$qb->getQuery()->getSQL(),$comments]);
