  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();
