MySQL的选择多列与和列

Question

让我们说我有这样一个表 -

id | name | salary 
01 | ABCD | 1000 
02 | EFGH | 2000  
03 | IJKL | 3000 

现在是有可能得到的结果这样设置？

id | name | salary | SUM 
01 | ABCD | 1000 | 6000 
02 | EFGH | 2000 
03 | IJKL | 3000 

我试过SELECT id, name, salary, SUM(salary) FROM table但它只是给了我一行。有没有办法让所有的行都有额外的列？

Answer 1

尝试：

SELECT id, name, salary, SUM(salary) AS sum FROM table 

编辑：想我误解了。也许这是你在找什么：

SELECT id, name, salary (SELECT SUM(salary) FROM table) AS sum FROM table 

Answer 2

SELECT 
    id, 
    name, 
    salary, 
    (SELECT SUM(salary) FROM table) 
FROM 
    table
