Question

我需要在基本的部门员工表中找到以下内容 sql员工工资高于部门平均工资的每个部门薪水最低的员工是什么我得到的是这个：

     select * from [Company Management].[dbo].[Employee]
      where Salary in
     (select min(Salary) from [Company Management].[dbo].[Employee]
      where salary>=All

   --average  employee salary for department
   (select avg(salary) from [Company Management].[dbo].[Employee]
   group by DepartmentID)
  group by DepartmentID
)

我得到的结果大于平均值而不是特定部门即如果部门1的平均值为50且部门2的平均值为37，则我得到部门1的正确答案，但部门2的答案为75，而部门2的员工则为40

Answer 1

选择员工每个部门的avarage工资。
与员工一起，找到最低工资，而不是每个部门的平均工资。
再次与员工联系，让所有员工在其所在部门获得该薪水。

以下是声明：

select employee.*
from employee
join
(
  select employee.departmentid, min(employee.salary) as sal
  from employee
  join
  (
    select departmentid, avg(salary) 
    from employee 
    group by departmentid
  ) avg_sals on avg_sals.departmentid = employee.departmentid and avg_sals.salary < employee.salary
  group by employee.departmentid
) wanted_sals on wanted_sals.departmentid = employee.departmentid and wanted_sals.sal = employee.salary;

SQL查询不成功
