 ### 方法一：等值连接 + 子查询
 
 我们可以使用等值连接，将 `Employee` 表和 `Department` 表连接起来，连接条件为 `Employee.departmentId = Department.id`，然后使用子查询来找到每个部门的最高工资，最后使用 `WHERE` 子句来筛选出每个部门中薪资最高的员工。

 ### Solution 1: Equi-Join + Subquery
 
 We can use an equi-join to join the `Employee` table and the `Department` table based on `Employee.departmentId = Department.id`, and then use a subquery to find the highest salary for each department. Finally, we can use a `WHERE` clause to filter out the employees with the highest salary in each department.
