I have the solution in pl/sql. Just go thru it.
declare
cursor c1 is select deptno from dept;
c2 c1%rowtype;
cursor c3(dno number) is
select rownum,sal from(select distinct sal ,deptno from emp where sal is not null order by sal desc ) where rownum<=6
and deptno=dno;
c4 c3%rowtype;
begin
open c1;
loop
fetch c1 into c2;
exit when c1%notfound;
dbms_output.put_line(c2.deptno);
for c4 in c3(c2.deptno) loop
dbms_output.put_line( c4.rownum|| ' ' ||c4.sal);
end loop;
end loop;
close c1;
end;

Hi ,
SELECT * FROM (
SELECT deptno, ename, sal,
DENSE_RANK()
OVER (
PARTITION BY deptno ORDER BY sal desc
) TopN FROM emp
)
WHERE TopN <= 6
ORDER BY deptno, sal DESC
