SQL & PL/SQL

i have a 2 sql statements with a union.

ex:

select sum(salary) as salary from dept
where dept_id=30
union
select sum(salary) as salary from dept
where dept_id=10

this query would show something like this:

salary
--------
20000
35000

I need the salary to display something like:

salary1 salary2
------------------------
20000 35000


Is this possible?


Thanks for having a look at this!
