选择并选择计数（聚合和非聚合在同一查询中）

Question

我有以下脚本。输出是行/列格式的XML数据。还有一个变量[Name]。

此时我只使用select语句。我需要的是在SELECT语句中的某些列（不是全部）的那笔

，需要加以汇总的列有：ColumnA，ColumnB，ColumnC

脚本：

;With CTE 
AS 
(
SELECT [Month] 
,[Name] 
,[Month_Code] 
,[ColumnA] 
,[ColumnB] 
,[ColumnC] 
FROM Fact_A 
INNER JOIN Dim_A on Fact_A.Key = Dim_A.Key 
INNER JOIN Dim_B on Fact_A_Key = Dim_B.Key 
WHERE Fiscal_Year = '20132014' 
) 

select [Name] AS [@name], 
(select [Month] as [column], 
null as tmp, 
ColumnA as [column], 
null as tmp, 
ColumnB as [column], 
null as tmp, 
ColumnC as [column] 
from CTE 
where [Name] = t.[Name] 
Order BY [Month_Code] 

for xml path('row'),type) as [*] 
from (select distinct [Name] from CTE)t 
for xml path('variable'),root('data')

如果我理解正确的，你想每个集群和月份这些柱的侧向承载力的总和，那么你可以尝试：

SELECT Month 
,Name 
,Month_Code 
,SUM(ColumnA) AS A 
,SUM(ColumnB) AS B 
,SUM(ColumnC) AS C 
FROM Fact_A 
INNER JOIN Dim_A on Fact_A.Key = Dim_A.Key 
INNER JOIN Dim_B on Fact_A_Key = Dim_B.Key 
GROUP BY Month, Name, Month_Code 
WHERE Fiscal_Year = '20132014' 

如果您不希望您总结的所有列，你可以使用其他一ggregate而不是SUM（），例如COUNT（）或MAX（）用于任何列
