SQL查询以根据时间范围计算金额

Question

我需要帮助以根据时间范围计算金额。另外，需要整个月进行计算。这是基于入住日期的班次交易计算。

eg：Shift 01/05/2019从8:00:00开始，结束于2019年2月5日07:59:59这是我的SQL

Select CONVERT(char(10), IsNull(CheckInDate, DateCheckIn), 120) Date, 
SUM(P.Amount - B.TourismTaxAmount) Amount 
From Bookings B 
Inner Join BookingPayments BP On B.ID = BP.BookingID 
Inner Join Payments P On P.ID = BP.PaymentID 
Where BookingStatus IN (2,3,4,6) and 
IsNull(CheckInDate, DateCheckIn) >= '2019-05-01 08:00:00' and
IsNull(CheckInDate, DateCheckIn) <= '2019-05-02 07:59:59'  
group by CONVERT(char(10), IsNull(CheckInDate, DateCheckIn), 120) 
order by CONVERT(char(10), IsNull(CheckInDate, DateCheckIn), 120) 

以下是输出：

-------------------------
| Date         | Amount |
-------------------------
| 2019-05-01   | 123.00 |
| 2019-05-02   | 456.00 |
-------------------------

此SQL已经正确..但是我该如何进行输出：

-------------------------
| Date         | Amount |
-------------------------
| 2019-05-01   | 579.00 |
-------------------------

以及从上面的。我需要按以下日期和输出生成每月班次摘要：

-------------------------
| Date         | Amount |
-------------------------
| 2019-05-01   | 579.00 |
| 2019-05-02   | 891.00 |
| 2019-05-03   | 721.00 |
| ..........   | .....  |
| ..........   | .....  |
-------------------------

感谢您的帮助和解决方案。谢谢

在进行聚合之前仅减去8小时。您最容易地执行此操作是定义一个带有您想要的日期表达式的变量(良好，列(，导致：

Select convert(char(10), v.dte, 120) as Date, 
       sum(P.Amount - B.TourismTaxAmount) as Amount 
From Bookings B Inner Join
     BookingPayments BP
     On B.ID = BP.BookingID Inner Join
     Payments P
     On P.ID = BP.PaymentID cross apply
     (values (convert(date, dateadd(hour, -8, coalesce(CheckInDate, DateCheckIn))))
     ) v(dte)
Where BookingStatus in (2, 3, 4, 6) and 
      v.dte >= '2019-05-01' and
      v.dte < '2019-05-02'  
group by v.dte 
order by v.dte;

这也将很容易扩展到多个日期或几个月。

使用window function sum((与订单按日期

Select CONVERT(char(10), IsNull(CheckInDate, DateCheckIn), 120) Date, 
SUM(P.Amount - B.TourismTaxAmount) over(order by CONVERT(char(10), IsNull(CheckInDate, DateCheckIn), 120)) Amount 
From Bookings B 
Inner Join BookingPayments BP On B.ID = BP.BookingID 
Inner Join Payments P On P.ID = BP.PaymentID 
Where BookingStatus IN (2,3,4,6) and 
IsNull(CheckInDate, DateCheckIn) >= '2019-05-01 08:00:00' and
IsNull(CheckInDate, DateCheckIn) <= '2019-05-02 07:59:59'  
order by CONVERT(char(10), IsNull(CheckInDate, DateCheckIn), 120)

对于sql-server，我将首先创建一个SQL，该SQL以

的形式以正确的格式带来了日期列

Select Year(myDate)*10000+Month(myDate)*100+Day(myDate) as MyNewDate ...

然后，如果您使用CTE内部的查询，则更容易分组。
