Employees And Their Department Who Is Top Salary

i have 2 tables emp and dept

emp has columns:
empid(pk),empname,deptid(fk),salary

dept has columns:
deptid(pk),deptname

now my aim is:
List of the employees and their department who is top salary earner of the department.

wht i can think of is:

select distinct empname,deptname,max(salary) as 'max salary'
from emp e,dept d
where e.deptid=d.deptid
group by empname,deptname

but it gives unexpected result...

help appreciated

cheers
