Using an update trigger to update another table

Question

The program I am working on has a poorly designed backend and basically there are two different tables needed to hold the exact same information. I am trying to write a trigger

Answer 1

You need to close every statement inside the trigger with a ;, and I do mean every.

CREATE TRIGGER `after_update_A` AFTER UPDATE ON `A` FOR EACH ROW
BEGIN
    UPDATE TABLE B
    SET  username = NEW.username
       , password = NEW.password
       , email = NEW.email
    WHERE id = NEW.id;    //<<-----------
END $$
