本文实例讲述了Symfony查询方法。分享给大家供大家参考，具体如下：

1. createQuery的写法

$sql = 'SELECT COUNT(DISTINCT(g.goodsId)) FROM AppBundle:GoodsIndex g WHERE g.status = :status';$params = array( 'status' => GoodsIndex::STATUS_NORMAL,);if (!empty($keywords)) { $params['keywords'] = "%{$keywords}%"; $sql .= ' AND g.keywords like :keywords ';} if (!empty($warehouseIdList)) { $params['warehouseIdList'] = $warehouseIdList; $sql .= " AND g.warehouseId IN :(warehouseIdList)"; }$goodsNum = $this->entityManager->createQuery($sql)->setParameters($params)->getSingleScalarResult();

个人总结：:是指占位符的意思，防止sql注入。所以把所有需要的参数做成数组$params里面。

2. getQuery的写法

$orderBy = 'p.'.$searchOptions['orderBy'];$repository = $this->entityManager ->getRepository('AppBundle:GoodsIndex');$query = $repository->createQueryBuilder('p');$query->select('DISTINCT(p.goodsId)');$query->where('p.keywords like :keywords') ->setParameter('keywords', "%{$searchOptions['keywords']}%") ->andwhere('p.status = :status') ->setParameter('status', GoodsIndex::STATUS_NORMAL) ->orderBy($orderBy, $searchOptions['order']) ->setFirstResult($pagination['pageSize'] * ($pagination['page'] - 1)) ->setMaxResults($pagination['pageSize']);if (!empty($searchOptions['warehouseIdList'])) { $query->andWhere($query->expr()->in('p.warehouseId', $searchOptions['warehouseIdList']));}$goodsIndexList = $query->getQuery()->getResult();
