Подсчет подытога в каждой группе

Question

Мне нужен отчет из нескольких таблиц. Я использую этот запрос (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]

что я хочу добавить одну строку после каждой группы с помощью расчета Если это тот же продукт и тот же код и магазин, мне нужно собирать покупку1 + Вход + Prch2 + SВход минус Продажи, Выход, Продажи2 Как это:

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

Спасибо

Не ROLLUP, но использование оператора WITH и UNION может сделать то же самое.

Суть в том, чтобы

• Сохранить исходный запрос в q, используя оператор WITH
• SELECT все из q
• Далее уточните GROUP BY снова из q, чтобы вычислить сальдо
• UNION результаты вместе
