查找所有员工入职时候的薪水情况，给出emp_no以及salary， 并按照emp_no进行逆序

CREATE TABLE employees (
emp_no int(11) NOT NULL,
birth_date date NOT NULL,
first_name varchar(14) NOT NULL,
last_name varchar(16) NOT NULL,
gender char(1) NOT NULL,
hire_date date NOT NULL,
PRIMARY KEY (emp_no));

CREATE TABLE salaries (
emp_no int(11) NOT NULL,
salary int(11) NOT NULL,
from_date date NOT NULL,
to_date date NOT NULL,
PRIMARY KEY (emp_no,from_date));

答案1：

select e.emp_no,s.salary from salaries as s
inner join employees as e
on s.emp_no=e.emp_no and e.hire_date=s.from_date
order by e.emp_no desc

答案2：

select e.emp_no, s.salary from employees aS e, salaries aS s
where e.emp_no = s.emp_no and e.hire_date = s.from_date
order by e.emp_no desc
