如何顯示不同的星期？

Question

我正在執行基於「運行總數」概念的SQL代碼。我的代碼正在計算準確的運行總數，但我需要在每週完成後才顯示運行總數，而不是按日期。

Select DISTINCT SD1.[Week], 
    SD1.[Allocation], 
    SD1.[Subsidiaries], 
    SD1.[Month], 
    SD1.[Date], 
    (SD1.[Daily Sale]+IsNull(SUM(SD2.[Daily Sale]),0)) as 'Running Total' 
from [dbo].[Solar data] SD1 
    left join [dbo].[Solar data] SD2 on SD1.[Subsidiaries]=SD2.[Subsidiaries] 
     and SD2.[Date]<SD1.[Date] And SD1.[Month]=SD2.[Month] 
where SD1.[Subsidiaries]='WCL' 
group by SD1.[Allocation], 
    SD1.[Month], 
    SD1.[Subsidiaries], 
    SD1.[Daily Sale], 
    SD1.[Week],SD1.[Date] 
order by SD1.[Week] 

+---------------+------------+------------+-----------+--------+-------+ 
| Subsidiaries | Allocation | Daily Sale | Date | Month | Week | 
+---------------+------------+------------+-----------+--------+-------+ 
| WCL   |  1075 | 44.93  | 2-Jan-17 | Jan-17 | Week1 | 
| WCL   |  1075 | 44.51  | 3-Jan-17 | Jan-17 | Week1 | 
| WCL   |  1075 | 53.68  | 8-Jan-17 | Jan-17 | Week2 | 
| WCL   |  1075 | 41.45  | 9-Jan-17 | Jan-17 | Week2 | 
| WCL   |  1075 | 40.97  | 15-Jan-17 | Jan-17 | Week3 | 
| WCL   |  1075 | 55.9  | 16-Jan-17 | Jan-17 | Week3 | 
| WCL   |  1075 | 43.89  | 22-Jan-17 | Jan-17 | Week4 | 
| WCL   |  1075 | 44.36  | 23-Jan-17 | Jan-17 | Week4 | 
| WCL   |  1075 | 35.13  | 29-Jan-17 | Jan-17 | Week5 | 
+---------------+------------+------------+-----------+--------+-------+ 

預期結果：

+--------+---------------+ 
| Week | Running total | 
+--------+---------------+ 
| Week1 | 89.44   | 
| Week2 | 184.57  | 
| Week3 | 281.44  | 
| Week4 | 369.69  | 
| Week5 | 404.82  | 
+--------+---------------+

你可以嘗試

Select DISTINCT SD1.[Week], 
    SD1.[Allocation], 
    SD1.[Subsidiaries], 
    SD1.[Month], 
    SD1.[Date], 
    SUM(Daily Sale) as 'Running Total' 
from [dbo].[Solar data] SD1 
where SD1.[Subsidiaries]='WCL' 
group by SD1.[Allocation], 
    SD1.[Month], 
    SD1.[Subsidiaries], 
    SD1.[Daily Sale], 
    SD1.[Week],SD1.[Date] 
order by SD1.[Week]
