Please correct if I am wrong

Question

Hi,
I am trying to maintain the users accounts but not sure that my approach is okay according to international standards or not?
create table users_payment(
p_id number(9) primary key,
co_id number(9) constraint usrs_payment references users(co_id),
payment_date timestamp(0) default sysdate,
duration number(3),/**1 is for one month upto 12 months**/
expire_date timestamp(0) default sysdate, /**Java JDBC code will update users_payment_info set expire_date=add_months(expire_date,3);**/
confirmed number(3),/**confirmation from 2 checkout. if paid=1 not_paid=0**/
status number(2)); /**I written a trigger here to auto change: if confirmed=1 && expire_date<today_date then set status 1 else 0**/
create sequence users_payment_seq
start with 1 increment by 1;
create or replace trigger users_payment_trig
before insert on users_payment
referencing new as new
for each row
begin
select users_payment_seq.nextval into :new.p_id
from dual;
end;
CREATE OR REPLACE TRIGGER users_payment_trig1
   BEFORE INSERT ON users_payment
   REFERENCING NEW AS NEW
   FOR EACH ROW
BEGIN
   IF :NEW.confirmed = 1 AND :NEW.expire_date < SYSDATE THEN
      :NEW.status := 1;
   ELSE
      :NEW.status := 0;
   END IF;
END;Thanks & best regards

This is a Java forum, not an SQL forum. Find a forum for the DB in question please.
