Question

我创建了一个名为 NOV_23 的表格，我希望得到最右边的部分和运输，膳食，住宿，其他，增值税和邮资的总和

CREATE TABLE NOV_23
(
EMPLOYEE_ID INT,
DIVISION VARCHAR (25),
LAST_NAME VARCHAR (25),
FIRST_NAME VARCHAR (25),
TRANSPORTATION INT,
LODGING INT,
TOTAL INT
);

然后我插入了一些值

INSERT INTO NOV_23 VALUES             
('1','DivA','LName1','FName1','1','1','')

INSERT INTO NOV_23 VALUES
('2','DivA','LName2','FName2','5','5','')

因此我得到的结果为：

  Employee_ID   Division Last_Name First_Name   Transportation   LODGING   TOTAL
  1             DivA     LNameA    FNameA       1                1       
  2             DivA     LNameB    FNameB       5                5

我可以通过使用更新来获得总数

  UPDATE NOV_23
  SET TOTAL = (Transportation + Lodging)
  WHERE Employee_ID = 1

和

  UPDATE NOV_23
  SET TOTAL = (Transportation + Lodging)
  WHERE Employee_ID = 2

我可以将结果作为

  Employee_ID   Division Last_Name First_Name   Transportation   LODGING         TOTAL
  1             DivA     LNameA    FNameA       1                1          2
  2             DivA     LNameB    FNameB       5                5         10

我想知道的是如何获取和显示交通总和（ 6 ），住宿总和（ 6 ）及其总体总和（6） +6 = 12 ）

    Employee_ID   Division Last_Name First_Name   Transportation   LODGING        TOTAL
  1             DivA     LNameA    FNameA       1                1          2
  2             DivA     LNameB    FNameB       5                5         10
  --            --       --        --           6                6         12

你可以计算小计和＆amp;使用rollup

累积

SELECT Employee_ID, Division, First_Name||' '||Last_Name Name,
       SUM(Transportation) AS Transportation,
       SUM(Lodging) AS Lodging,
       SUM(Total) AS Total
  FROM nov_23
 GROUP BY ROLLUP (Employee_ID, Division, First_Name||' '||Last_Name)
 ORDER BY Employee_ID, Division, First_Name||' '||Last_Name;

你可以计算小计和＆amp;使用cube

指定的所有维度组合的累积量

SELECT Employee_ID, Division, First_Name||' '||Last_Name Name,
       SUM(Transportation) AS Transportation,
       SUM(Lodging) AS Lodging,
       SUM(Total) AS Total
  FROM nov_23
 GROUP BY CUBE (Employee_ID, Division, First_Name||' '||Last_Name)
 ORDER BY Employee_ID, Division, First_Name||' '||Last_Name;

如何得到表的所有总和？
