Yes, the trigger code is works. Many thanks !! Now I understand the use of delimiter command. Thanks again... =)
My next question is, do we able to view the triggers that has been created ? And how ?

This is necessary when you want to use a ";" in your actual statement. In this case, the entire trigger definition is considered one statement, but the ";" in the "DELETE..." line is being interpreted as the termination of it. Yes, it's dumb.
