SQL count語句

Question

我有一個表名作爲JOB_Details和數據顯示如下：

Age   Department:IT   
       Male  Female 
30yrs   5   1    
30-34yrs  3   2    
35-39yrs  4   4    
40-49yrs  2   3    
50-54yrs  1   0    

，並假設輸出會喜歡：

Age   Department:IT   Total 
       Male  Female 
30yrs   5   1    6 
30-34yrs  3   2    5 
35-39yrs  4   4    8 
40-49yrs  2   3    5 
50-54yrs  1   0    1 
Total   15   10    25 

我該怎麼辦呢？因爲當使用計數和按功能分組時，結果結果將不是我想要的。有人能介意給我一些建議嗎？爲了您的信息，我使用Oracle。

Answer 1

SELECT AGE, MALE, FEMALE, SUM(MALE + FEMALE) AS TOTAL 
FROM JOB_DETAILS 
GROUP BY AGE 

編輯：

如果你想運行總，你將不得不使用ROLLUP（SQL Server）的

SELECT AGE, MALE, FEMALE, SUM(MALE + FEMALE) AS TOTAL 
FROM JOB_DETAILS 
GROUP BY AGE 
WITH ROLLUP 

Answer 2

嘗試使用union all這樣的：

SELECT age, Male, Female, nvl(Male,0) + nvl(Female,0) as total 
FROM JOB_Details 
union all 
SELECT 'TOTAL', sum(Male), sum(Female), sum(nvl(Male,0) + nvl(Female,0)) 
FROM JOB_Details 

觀看次數：

create view vJOB_Details 
SELECT (CASE WHEN age='30' THEN Count(EMPLID) 
      WHEN age='34' THEN Count(EMPLID) 
      WHEN age='39' THEN Count(EMPLID) 
      WHEN age='49' THEN Count(EMPLID) 
      WHEN age='54' THEN Count(EMPLID) 
      ELSE NULL 
     END) TOTAL_COLUMN , 
     (CASE WHEN GENDER1='M' THEN Count(EMPLID) 
       WHEN GENDER1='F' THEN Count(EMPLID) 
       ELSE NULL 
     END) TOTAL_GENDER 
FROM job_details 
GROUP BY age,GENDER 

SELECT age, Male, Female, nvl(Male,0) + nvl(Female,0) as total 
FROM vJOB_Details 
union all 
SELECT 'TOTAL', sum(Male), sum(Female), sum(nvl(Male,0) + nvl(Female,0)) 
FROM vJOB_Details;
