非常适合练习case when的题，就相当于java的swich case
SELECT e.emp_no, e.first_name, e.last_name, eb.btype, s.salary, CASE WHEN eb.btype = 1 THEN s.salary * 0.1 WHEN eb.btype = 2 THEN s.salary * 0.2 ELSE s.salary * 0.3 END bonus FROM emp_bonus AS eb, employees AS e, salaries AS s WHERE eb.emp_no = e.emp_no AND s.emp_no = e.emp_no AND s.to_date='9999-01-01';
