SQL Server包含where和group by的多行总和

我有一个

SQL

表

Details

，列名为

ITEMS

，

TotalOrder

，

CancelOrder

我这样写查询

select Items, SUM(TotalOrder) as [TotalOrder], SUM(CancelOrder)as [CancelOrder] ,Source from Details group by Items

  ITEMS        TotalOrder    CancelOrder 
  Laptop         102            5
  Desktop        9              1
  Tablet         17             0
  Tshirt         119            12
  TV             5              0

结果是这样的

select Items, SUM(TotalOrder) as [TotalOrder], SUM(CancelOrder)as [CancelOrder] ,Source from Details group by Items

  ITEMS        TotalOrder    CancelOrder 
  Laptop         102            5
  Desktop        9              1
  Tablet         17             0
  Tshirt         119            12
  TV             5              0

但是我的列名

项目

和数据

笔记本电脑

，

台式电脑

，

平板电脑

与

笔记本电脑

的名称相同，这就是为什么我希望得到类似的输出

  ITEMS        TotalOrder    CancelOrder 
  Laptop         128            6
  Tshirt         119            12
  TV             5              0

试试这个

select Items, SUM(TotalOrder) as [TotalOrder], SUM(CancelOrder)as [CancelOrder] 
from Details 
where Items NOT IN('Laptop','Desktop','Tablet')  group by Items 
UNION 
select 'Laptop',SUM(TotalOrder) as [TotalOrder], SUM(CancelOrder)as [CancelOrder] 
from Details 
where Items IN('Laptop','Desktop','Tablet')
