MySQL选择多列和SUM列

Question

Lets说我有一张这样的桌子 -

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

现在可以得到这样的结果集吗？

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，但它只给了我一行。有没有办法让所有行都有一个额外的列？

Answer 1

尝试：

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

编辑：想想我被误解了。也许这就是你要找的东西：

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
