symfony的查询总结

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();
