Highest Salary in each department

Question

I have a table EmpDetails:

DeptID      EmpName   Salary
Engg        Sam       1000
Engg        Smith     2000
HR          Denis     1500
HR                  


        

Answer 1

As short as the question:

SELECT DeptID, MAX(Salary) FROM EmpDetails GROUP BY DeptID

Answer 2

If you just want to get the highest salary from that table, by department:

SELECT MAX(Salary) FROM TableName GROUP BY DeptID

Answer 3

Use the below quesry:

select employee_name,salary,department_id from emp where salary in(select max(salary) from emp group by department_id);

Answer 4

***

> /*highest salary by each dept*/

***
select d.Dept_Name,max(e.salary)
    from emp_details as e join Dept_Details as d
    on e.d_id=d.Dept_Id
    group by  d.Dept_Name

select  distinct e.d_id,d.Dept_Name
    from emp_details as e join Dept_Details as d 
    on e.d_id=d.Dept_Id

select  e.salary,d.Dept_Name,d.Dept_Id
    from emp_details as e join Dept_Details as d 
    on e.d_id=d.Dept_Id

/////simplest query for max salary dept_wise////

Answer 5

Not sure why no one has mentioned the Group By .... Having syntax. It specifically addresses these requirements.

select EmpName,DeptId,Salary from EmpDetails group by DeptId having Salary=max(Salary);

Answer 6

Select empname,empid,Sal,DeptName from 
(Select e.empname,e.empid,Max(S.Salary) Sal,D.DeptName, ROW_NUMBER() Over(partition by D.DeptName order by s.salary desc) Rownum
from emp e inner join Sal S
on e.empid=s.empid 
inner join Dept d on e.Deptid=d.Deptid
group by e.empname,e.empid,D.DeptName,s.Salary
) x where Rownum = 1
