计算每组的小计

Question

我需要来自多表的报告我使用这个查询（SQL Server）

Select  CASE When ([bills].[BT] ='0' and [bills].[T] = 1 )Then 'Purchas1'
When([bills].[BT] ='0' and [bills].[T] = 3 ) Then 'Output'
When([bills].[BT] ='0' and [bills].[T] = 4 ) Then 'Input' 
When [bills].[BT] ='1'  Then  'ٍSales'
When [bills].[BT] = '2' Then  'Prch2'
When [bills].[BT] = '3' Then  'ٍSales2'
When [bills].[BT] = '4'  Then 'SInput' 
END AS BillType,
[mat].[Name] as Product,
[mat].[Code], [store].[Name], 
SUM( [billInfo].[qty]) as Qtys 
from [mat],[billInfo000],[store],[bu],[bills] 
Where [bu].[TG] =[bills].[g]
and [billInfo].[ParentGUID] =[bu].[g] 
and [billInfo].[StoreGUID] =[store].[g] 
and [billInfo].[MatGUID] = [mat].[g] 
Group by [bills].[BT],[bills].[T],[mat].[Name], 
[mat].[Code],[store].[Name] ,[mat].[qty]

我想要的是在每组之后用计算添加一行 如果它是相同的产品和相同的代码和商店我需要 收集purchase1+Input+Prch2+SInput减去Sales、Output、Sales2 像这样：

账单类型 |产品 |代码 |姓名 |数量 -------- -------- ---- ---- ---- Purchas1 Pro1 001 主要 150 输出 Pro1 001 主 10 销售 Pro1 001 主要 30 Purch2 Pro1 001 主要 50 Balance Pro1 001 主 160 输出 Pro1 001 分支 10 销售 Pro1 001 分公司 10 Balance Pro1 001 Brabch -20

谢谢

不是ROLLUP，而是使用WITH 语句和UNION 也可以做到这一点。

它的要点是

• 使用WITH 语句将原始查询存储在q 中
• SELECT全部来自q
• 再次从q进一步细化GROUP BY以计算余额
• UNION结果一起
