我有以下表结构:
品牌=>历史< =用户
Histories表包含以下列:
brandId,userId,指向(每个品牌用户得分数点数)。我需要在历史表中的两个日期之间为用户所得的所有积分求和。
查询将接受4个参数:userId,brandId,startDate,endDate ...以下输出类似于:
userId brandId points
1 64 155 sum of all points in between two dates specified by the parameter.
如果BrandId的传递值为null(即未通过)。如果在BrandId和UserId的历史表中没有找到任何数据,查询应该返回关于品牌和用户的整个数据...我在Zend Framework 2中编写了我自己的查询,但它没有输出我想要的(仅返回历史表中实际找到的记录)...
看起来像这样:
public function BrandWallBrandsById($userId,$brandId,$startDate,$endDate)
{
$select = new Select();
$select->from(array('p' => $this->table), array('id'));
$select->join(array('b' => 'brands'), 'p.brandId = b.id', array('id','name', 'cover', 'slogan', 'startDate', 'homepage','endDate','active'));
$select->columns(array(new Expression('SUM(p.points) as points'), "userId", "brandId"));
$select->order("p.points asc");
$select->group("p.brandId");
$where = new Where();
$where->notEqualTo("p.points", 0);
$where->notEqualTo("p.type",10);
$where->equalTo("p.userId", $userId);
$where->equalTo("p.brandId", $brandId);
$where->equalTo("b.active",1);
$where->between("p.time", $startDate, $endDate);
$select->where($where);
return $this->historyTable->selectWith($select)->toArray()[0];
}
请注意,查询只会在其被调用时返回单个记录。我想写一个纯SQL语句,因为我认为它可能比这更容易... 有人可以帮助我吗?

这是一个SQL语句,可以让你在SQL Server中得到你想要的东西,虽然我不熟悉zend-framework。
declare @startDate datetime, @endDate datetime, @userId int = null, @brandId int = null
set @startDate = '6/1/2016'
set @endDate = '6/9/2016'
set @userId = 1 --this can be NULL
set @brandId = 64 --this can be NULL
select
userId,
brandId,
sum(points) as points
from
historyTable
where
(@userId is null or userId = @userId)
and (@brandId is null or brandId = @brandId)
and dateColumn >= @startDate
and dateColumn < dateadd(day,1,@endDate)
group by
userId, brandId
