这篇文章主要介绍了Symfony查询方法,结合实例形式总结分析了createQuery与getQuery查询数据的具体使用技巧,需要的朋友可以参考下

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();
