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

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);
