I'm trying to create a trigger in DB2 that will prevent any one from updating any personal information that does not belong to them I.E. FIRST_NAME, LAST_NAME, EMAIL , PHONE_NUMBER columns. I'm trying to make it so individuals are the only ones allowed to update their own personal information by username I.E. the current user can only update information associated with the current username. What is the proper syntax for creating this trigger, I am struggling to get it right.
