How to insert last update date and user id to a form?

Question

Hi,
I have created a form to enter data to a custom table.
When a new record is created, I would like to keep track of the creation date, last update date and who (user id) enters the form.
Can someone please help or point me to a right place to look for this information?
Thank you!

Create four new columns in your table called Created_On, Created_By, Last_Updated_On and Last_Updated_By.
You can create a trigger to accomplish the rest:
create or replace trigger "<name of your trigger>"
  before insert or update on "<name of your table>"
  for each row
begin
  if inserting then
    :NEW.Created_On := sysdate;
    :NEW.Created_By := v('APP_USER');
  end if;
  if updating then
    :NEW.Last_Updated_On := sysdate;
    :NEW.Last_Updated_By := v('APP_USER');
  end if;
end;Every time you'll add or modify data in that table, the trigger will automatically fill those fields.
