根据另外几列的标准计算不同的一列

Question

我有样本数据:: Data-Sample

我试图根据3个列中的2个标准计算不同的'CustID':

1. '销售'和'积分'不能都是'0'
2. 'OrderType'仅在(1,2,3)中

因此,我创建了一个额外的列'TestSUM',它将'Sales'和'Points'相加,它们不等于0,以满足标准#1

使用下面的代码,我可以根据我的标准#1执行不同的CustID计数时排除CustID FFF和GGG:

Select 
Country
, o.Year
, o.Month
, sum(o.Sales) 
, sum(o.Points)
, sum(o.Sales + o.Points) as 'TestSUM'
, o.OrderType

From FactOrders O
Join CustTable as C on o.CustID = c.CustID
and o.OrderType in (1,2,3) 

Group by 
Country
, o.Year
, o.Month
, o.OrderType
, c.CustID

having sum(o.Sales + o.Points) <> 0   

Order by
c.CustID

但是,我希望我的结果看起来像是这样的:

  Country   Year  Month  Distinct Count   Sales  
 Singapore  2018     10               6  2048.06 
 Singapore  2018     11               7  1996.61 

如何修改我的脚本以删除"CustID","Point","TestSUM","OrderType"列,但仍保留反映标准的独特计数

having sum(o.Sales + o.Points) <> 0 

评论详情:

我希望每个客户应用sales + points <> 0条件,但当我从group中删除CustID,Point,TestSum和OrderType并且选择时,结果返回到CustID不显示行,sales + points <> 0条件没有不再适用于每个客户...... CustID的独特数量将包括销售额+点数> 0的行数

Answer 1

也许你可以像下面这样做。请注意，我删除了 CustTable 的 JOIN，因为它没有被使用。如果 FactOrders 和 CustTable 之间没有引用完整性，您可以保留它。

我将您的必须移动到您正在计算客户的位置，即使他们有一行是 0 和 0。

    o.OrderType in (1,2,3) and (o.Sales<>0 or o.Points<>0)
