DELIMITER $$

CREATE TRIGGER ai_jos_jquarks_quizzes_each AFTER INSERT ON jos_jquarks_quizzes 
FOR EACH ROW
BEGIN
    INSERT INTO jos_users_trainings
      (quiz_id) VALUES (new.id); 
END $$

DELIMITER ;

In a trigger the virtual table new holds the newly inserted values.

In an update or delete trigger the virtual table old holds the values before the change.
