How to Copy the specific record of one table to other table(same structure)

Question

Hello,
i have develop a form and some buttons on it. Suppose that Form is based on TABLE_1, which has the fiollowing structure.
( Bill_No Number(5),
Bill_Date Date,
Bill_amount Number(6),
Description Varchar2(60)
My requirement is when i save the any record and after that i want to copy all the contents of that record to Table_2.
On the form there is a button named as Let say "Copy current Record to Table_2". So when i press the button, the record is copied from Table_1 to Table_2.
(Note: - Table_2 has the same structure as Table_1.)
Please help me to solve this problem.
Thanks in advance.

i would prefer a pure database-solution, means put a database-trigger BEFORE INSERT FOR REACH ROW on your table 1 and do the insert there.
If you do it in PRE-INSERT-Trigger in forms it will work for data entered via forms-application, but what happens if data is inserted via a different frontend?
CREATE OR REPLACE TRIGGER TRG_TABLENAME_BRI
BEFORE INSERT
ON TABLENAME
FOR EACH ROW
BEGIN
  -- Do your insert here
  INSERT INTO TABLE2 (
    COL1,
    COL2
  ) VALUES (
    :NEW.COL1, -- (or OLD.COL1)
    :NEW.COL2  -- (or OLD.COL2)
END;
