別週を表示するにはどうすればよいですか？

Question

私は "実行中の合計"コンセプトに基づいてSQLコードを実行しています。私のコードは正確な稼働合計を計算していますが、実行中の合計を日付ではなく毎週の完了後に表示する必要があります。

+---------------+------------+------------+-----------+--------+-------+ 
| 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 | 
+---------------+------------+------------+-----------+--------+-------+ 

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]

| Week1 | 89.44   | 
| Week2 | 184.57  |

    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]
