计算每组的小计

Question

我需要来自多表的报告我使用此查询（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]

我想要的是在每个组之后使用Calculating添加一行 如果它是相同的产品和我需要的相同代码和商店 收集purchase1 + Input + Prch2 + SInput减去Sales，Output，Sales2 像这样：

BillType | Product | Code | Name | Qtys 
--------   -------   ----   ----   ---- 
Purchas1   Pro1      001    Main    150
Output     Pro1      001    Main    10
Sales      Pro1      001    Main    30
Purch2     Pro1      001    Main    50
Balance    Pro1      001    Main    160
Output     Pro1      001    Branch  10
Sales      Pro1      001    Branch  10
Balance    Pro1      001    Brabch  -20

由于

Answer 1

不是ROLLUP但使用WITH语句和UNION也可以做到这一点。

它的要点是

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