MySQL created_by or updated_last-by
Okay I figured it out. No Need for Delimiters because it is technically one line or one statement and only needs one semicolon. Also make sure to notice that one is for before an Insert and one before an Update. I believe that SET was also necessary. 

CREATE TRIGGER CREATE_BY_MENU_TR 
BEFORE INSERT ON MENU 
FOR EACH ROW 
SET NEW.Create_By = CURRENT_USER();

CREATE TRIGGER CREATE_BY_MENU_TR 
BEFORE UPDATE ON MENU 
FOR EACH ROW 
SET NEW.Last_Update_By = CURRENT_USER();


The Create_By and Last_Update_By are just columns of data type varchar.
