Answer / yuvaevergreen

Since there is no common column, it may not be possible to
join two tables.
if deptno is in emp table, correlated query can be used
emp
eno ename sal deptno
1 yuva 10 tn1
2 yuv1 20 tn2
3 yuv3 30 tn1


select * from emp as e1
where sal in
(sel max(sal) from emp as e2
where e1.deptno=e2.deptno);
