數據總結多次

下面是我遇到的問題。一切工作很好，直到我添加了「亞洲」的線。這個信息必須來自一個新表，所以我不得不做一個新的連接。一旦我做到了這一點，我開始對這些信息產生問題。問題是CDS_MailPlayer可以爲同一個人擁有多個Mail_ID。然後，它會爲每個Mail_ID執行所有Sum，然後將它們一起添加。因此，如果玩家顯示100美元的實際值，但有2個郵件編號，他們的實際值將以200美元出現。如果他們有10個電子郵件ID，那麼他們的實際價值將猛漲至1000美元。數據總結多次

我該如何添加一張支票來查看某人是否有161到166之間的郵件ID，而不會搞亂我的數學？

此外，還有一個方法可以修改Where子句以將滾動條拉長12個月，如果您在2014年12月的任何一天拉取報表，它將拉動12/1/2013-11/30/2014但如果您在2015年1月提交報告，則日期範圍將更改爲2014年1月1日/ 2014年1月1日。我儘可能接近知道如何知道。

和往常一樣，關於如何清理代碼並使其更快/更好的任何建議都將被讚賞，對於SQL來說還是一個新的東西。

使用SQL Server 2000中

嘗試這三個小的變化，以解決您的主要問題：

1）選擇部分：

,case when isnull(M.Mail_ID_sp,0) = 0 Then 'N' else 'Y' end as "Asian"

2）在表中加入部分：

left outer Join (SELECT Player_ID, count(*) as Mail_ID_sp FROM dbo.CDS_MAILPLAYER where M.Mail_ID between '161' and '166' GROUP BY Player_ID) as M

3）最後通過以下分組來平衡羣組：

,case when isnull(M.Mail_ID_sp,0) = 0 Then 'N' else 'Y' end -- Balancing Group By
