Question

我需要扩展我的sql查询，返回子总数和＆amp;总计。有没有办法通过此查询返回子总计和总计：

我有这样的数据：

Department Employee Sal
A          Jack     1000          
A          Pack     1000          
A          Dack     1000          
B          BEN     1000          
B          HEN     1000          
C          SIN     1000

我想要这个，即小计＆amp;所有部门的总数

Department Employee Sal
A          Jack     1000          
A          Pack     1000          
A          Dack     1000      
A_Sub_Total         3000      
B          BEN      1000          
B          MAT      1000          
B_Sub_Total         2000      
C          SIN      1000  
C_Sub_Total         1000    
Total               6000

我尝试使用计算功能，即＆＃34;计算总和（Sal）由部门＆＃34; 它无法正常工作

Answer 1

试试这个：

SELECT [Department], [Employee], [Sal]
FROM #mytable

UNION ALL

SELECT [Department] + '_Sub_Total',
       NULL,
       SUM([Sal]) AS Sal
FROM #mytable
GROUP BY [Department] 

UNION ALL

SELECT 'Total', NULL, SUM([Sal]) AS Sal
FROM #mytable 
ORDER BY Department

Answer 2

您可以使用WITH ROLLUP。

SELECT ISNULL(Department, 'Total'), ISNULL(Employee, Department + '_Sub_Total'), SUM(Sal) AS Sal FROM [test] GROUP BY Department, Employee WITH ROLLUP

小计＆amp;总计与总计
