Is there an automatic modification time stamp type for Oracle columns?

Question

Is there a way to create a timestamp column in Oracle that automatically stores a timestamp of when the record has changed ?

Answer 1

For oracle I usually use a trigger to update the timestamp field

CREATE OR REPLACE TRIGGER update_timestamp 
  BEFORE INSERT OR UPDATE ON some_table
  FOR EACH ROW
BEGIN
  :NEW.TS := systimestamp;
END;

Oracle does not seem to have a built-in attribute for updating the timestamp field to the current timestamp (unlike other DBs like MySQL).
