SQL & PL/SQL

Hello,

I would like to know if it possible to CREATE TABLE with formated date;

create table months
(id number,
(month_col to_char( month_col,'MM'));

so when I insert

insert into months values (1,sysdate); 

And query

select *from months;

I would get

id     months_col
-----------------------------
1           04

I know this could easily be done by cerating a view on a table, but I was wondering if this was possible to implement directly into table.
I browesed through the documentation, but did not find any datatype that would support this.

Thank you for replies.
