部门工资最高的员工

思路

1 此题分为两个步骤，一是寻找每组内的最高薪水，而是按照同指标对两表进行连接
2 此题借鉴了我之前的一个博文select套娃
以下为我的代码，在Heidi SQL中运行成功，但是在LeetCode中出现问题

select
department.name as deparment ,
employee.name as employee,
salary  from employee,department
where salary in (select
max(salary) as max_salary
from employee
group by departmentid)
and employee.departmentid=department.id

下面贴上评论中运行成功的代码源代码出处

select
d.Name as Department,
e.Name as Employee,
e.Salary
from
Employee e,Department d
where
e.DepartmentId=d.id
and
(e.Salary,e.DepartmentId) in (select max(Salary),DepartmentId from Employee group by DepartmentId);
