https://www.nowcoder.com/practice/c1472daba75d4635b7f8540b837cc719
select b.emp_no,a.salary,b.last_name,b.first_name
from salaries as a inner join employees as b on a.emp_no = b.emp_no
where salary in
(select max(salary)
from salaries
where salary not in
(
select max(salary)
from salaries
))
用max找出最大值后，原表not in 排除最大值，剩下的数据使用max就是第二大值了
