我怎么会觉得使用MYSQL第二大的薪水[关闭]

Question

我怎么会去查询从我的Employee表中的所有员工的第二大薪水是多少？在MySQL

Answer 1

试试这个，它应该必须工作。

SELECT name, salary
FROM employees
WHERE salary = (SELECT MAX(salary) FROM employees WHERE salary < (SELECT MAX(salary) FROM employees))

或者你可以试试这个为好。

/* looking for 2nd highest salary -- notice the '=2' */
SELECT name,salary FROM employees
WHERE salary = (SELECT DISTINCT(salary) FROM employees as e1
WHERE (SELECT COUNT(DISTINCT(salary))=2 FROM employees as e2
WHERE e1.salary <= e2.salary)) ORDER BY name

Answer 2

薪金降序排列，然后用LIMIT：

select *
from employees
order by salary desc
limit 1,1

第一装置1来跳过第一行，所述第二装置1返回一行。

Answer 3

你可以试试下面 -

  select name, max(salary) from employee where salary < (select max(salary) from employee)
    group by name;
