SELECT s.emp_no,s.salary,
e.last_name,e.first_name
FROM salaries s
JOIN employees e USING(emp_no)
WHERE s.salary = (
SELECT max(salary)
FROM salaries
WHERE salary < (
SELECT max(salary)
FROM salaries
WHERE to_date = '9999-01-01'
)
and to_date = '9999-01-01'
) and s.to_date = '9999-01-01'
1、找到最大的薪资水平

2、找到第二大的薪资水平
SELECT max(salary)
FROM salaries
WHERE salary < (
SELECT max(salary)
FROM salaries
WHERE to_date = '9999-01-01'
)
and to_date = '9999-01-01'
3、输出该员工信息
SELECT s.emp_no,s.salary,
e.last_name,e.first_name
FROM salaries s
JOIN employees e USING(emp_no)
WHERE s.salary = (
SELECT max(salary)
FROM salaries
WHERE salary < (
SELECT max(salary)
FROM salaries
WHERE to_date = '9999-01-01'
)
and to_date = '9999-01-01'
) and s.to_date = '9999-01-01'
