Symfony查询方法实例小结


            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();
