Answer 1

您需要一个分隔符

delimiter //

CREATE TRIGGER ProductStatusHistory_3 
AFTER UPDATE ON catalog_product_entity_int
FOR EACH ROW BEGIN
  IF (OLD.value <> NEW.value) THEN
   INSERT INTO tbl_product_status_history
   (entity_id,oldvisible,newvisible,datetime)    
   values
   (
     NEW.entity_id,OLD.value,NEW.value,NOW()
    );
  END IF;
END;//

delimiter ;
