partition clause can be use either right or left side of the
outer-join but no on both
partition clause can't be used with full outer join
can't use sub-query after partition clause is used in outer
join-on
SQL:
select d.deptno,substr(d.loc,1,5)"loc",
row_number() over (partition by d.deptno order by d.deptno)"rn",e.job,
e.ename from dept d right outer join emp e on e.deptno = d.deptno
where d.deptno in (10, 30)
