SQL & PL/SQL

Hi everybody,
Can anyone help me to load data from a query to excel file ?
This has to be done in a procedure, but not in manual method.

I will tell you my requirement with an example query of emp and dept table.

select e.ename,e.sal,d.dname
from emp e, dept d
where e.deptno=d.deptno;

The result of this query has to load in an excel file.


Thanks in advance.
