这样就可以了。

SELECT E1.DEPT, E2.ENAME, E1.HIGHEST_SALARY
FROM
(SELECT DEPT, MAX(SALARY) HIGHEST_SALARY
FROM EMPLOYEE
GROUP BY DEPT) E1
INNER JOIN EMPLOYEE E2 ON E1.HIGHEST_SALARY = E2.SALARY
AND E1.DEPT = E2.DEPT

Answer 5

select * from (select salary,last_name,dense_rank()
over (order by salary desc)
sal_rank from employees) where sal_rank <=3;

全部......这是下面的输出：

SALARY LAST_NAME                   SAL_RANK
---------- ------------------------- ----------
 24000 King                               1
 17000 Kochhar                            2
