Question

在这个数据仓库中，我们有一个由多个组织组成的组织，

我有[FactFinance]表，其中包含有关每个组织收入的信息。

我在数据仓库中有以下查询，它从[组织维度表]中选择（组织名称），从[FactFinance表]中选择其（总收入金额），以及它（总收入金额）表示的百分比来自整个组织的总收入金额

select  [DimOrganization].[OrganizationName] ,  SUM([Amount])as TotalAmountIncome , SUM([FactFinance].[Amount])/(select sum([FactFinance].[Amount]) 
from   [FactFinance] ) PercentageOfTotalSales
from   [FactFinance] , [DimOrganization]
Where [FactFinance].[OrganizationKey]= [DimOrganization].[OrganizationKey]
group by ([DimOrganization].[OrganizationName])
order by SUM([Amount]) desc

结果如下表所示：

+--------------------+-------------------+------------------------+
|  OrganizationName  | TotalAmountIncome | PercentageOfTotalSales |
+--------------------+-------------------+------------------------+
| Canadian Division  | 292174782.72      | 0.215049383184007      |
| Southeast Division | 279284663.6       | 0.205561869784944      |
| Southwest Division | 232365970.6       | 0.171028307731715      |
| Central Division   | 149032081.6       | 0.109692071726198      |
| Northwest Division | 138922888.8       | 0.102251403315702      |
| Northeast Division | 134003346.4       | 0.0986304728958399     |
| France             | 66963799.96       | 0.0492873606099529     |
| Australia          | 35553074.99       | 0.0261681270906303     |
| Germany            | 30339804.03       | 0.0223310036610101     |
+--------------------+-------------------+------------------------+

我想修改此查询，以便只选择收入最高且占整个组织总收入近60％的组织。

如果我计算前三行中的百分比，即具有最大收入的组织

+------------------------+
| PercentageOfTotalSales |
+------------------------+
| 0.215049383            |
| 0.20556187             |
| 0.171028308            |
+------------------------+

结果将是：0.591639561 几乎是60％

所以结果必须是前三行（这意味着整个组织总收入的近60％？）

我尝试了以下查询，但它给了我错误（无效的列名'PercentageOfTotalSales'）。

select  [DimOrganization].[OrganizationName] ,  SUM([Amount])as TotalAmountIncome , SUM([FactFinance].[Amount])/(select sum([FactFinance].[Amount]) 
from   [FactFinance] ) PercentageOfTotalSales
from   [FactFinance] , [DimOrganization]
Where [FactFinance].[OrganizationKey]= [DimOrganization].[OrganizationKey]
 AND SUM(PercentageOfTotalSales) >= 0.60
group by ([DimOrganization].[OrganizationName]) 

order by SUM([Amount]) desc

我尝试了不同的方法，但总是给我错误。

我可以得到任何建议吗？

Answer 1

您可以使用Running Total查询并将返回的表用作子查询，如下所示：

    SELECT  [DimOrganization].OrganizationName , Value  from (


SELECT   x, Value, (SELECT SUM(Value) FROM (select top 10  [FactFinance].[OrganizationKey] as x,SUM([Amount]) as [Amount] , SUM([Amount]) / 
(select sum([Amount]) from [FactFinance])as Value

FROM [FactFinance] group by([FactFinance].[OrganizationKey]) order by SUM([Amount]) desc) T2  

WHERE T1.value <= T2.value) AS RunningTotal

FROM (select top 10  [FactFinance].[OrganizationKey] as x,SUM([FactFinance].[Amount])as [Amount] , SUM([FactFinance].[Amount])/(select sum([FactFinance].[Amount]) 
from [FactFinance])as Value
from [FactFinance] group by([FactFinance].[OrganizationKey]) order by SUM([FactFinance].[Amount]) desc) T1 ) allTable , [DimOrganization] where allTable.x = [DimOrganization].OrganizationKey AND RunningTotal<0.6

Answer 2

如果没有要测试的表结构，这应该可行。

SELECT [DimOrganization].[OrganizationName]
    ,SUM([Amount])as TotalAmountIncome
    ,SUM([FactFinance].[Amount])/TotalSales.Amount) PercentageOfTotalSales
FROM [FactFinance]
INNER JOIN [DimOrganization]
    ON [FactFinance].[OrganizationKey]= [DimOrganization].[OrganizationKey]
OUTER APPLY (
    SELECT SUM([FactFinance].[Amount])  Amount
    FROM [FactFinance]
    ) TotalSales
GROUP BY [DimOrganization].[OrganizationName]
HAVING SUM(PercentageOfTotalSales) >= 0.60
ORDER BY SUM([Amount]) DESC

对于不同的百分比，您可以使用视图并传入一系列可容忍的值来实现它。
