計數和SUM使用情況

我有臺這樣的，名稱：Table.dbo計數和SUM使用情況

Amount Desc Month SM code ID

我寫此查詢：

select 
[SM], 
    count(*) as TotalCntOfSM, 
    sum(case when [code] between 4 and 27 then 1 else 0 end) as TotalCntOfSM_R, 
    sum(case when [code] in (1,2,3) then 1 else 0 end) as TotalCntOfSM_B, 
    sum(case when [code] in (1) then 1 else 0 end) as TotalCntofSM_B1, 
    sum(case when [code] in (2) then 1 else 0 end) as TotalCntofSM_B2, 
    sum(case when [code] in (3) then 1 else 0 end) as TotalCntofSM_B3, 
    sum([Amount]) As TotalAmount 
    ****[How can I sum the Amount for the SM if the code is between 4 and 27?** For example]** 
from [Table] 
group by [SM] 
order by TotalCntOfSM desc

我如何可以總結的金額爲SM如果代碼介於4到27之間，或者代碼僅在（1,2,3）中（例如）。

非常感謝！

含義4和27之間是否包含？如果是，它基本上在1到27之間？ –

用'然後SM'替換'然後1'？ – qxg

[SM]列中有一些字符串值。計算SUM（[SM]）時可以嗎？ –

酷似QXG說 - 如果你想起來總代碼量之間4和27或代碼1,2,3

sum(case when [code] between 1 and 27 then [Amount] else 0 end) as SMAmount 
You can write the above also as 
sum(case when [code] between 4 and 27 OR [code] in (1,2,3) then [Amount] else 0 end) as SMAmount

與

sum(case when [code] between 4 and 27 then [Amount] else 0 end) as SMAmount

更換

****[How can I sum the Amount for the SM if the code is between 4 and 27?** For example]** `
