в базе данных создаю таблицу
create table work_done (
id_work int not null auto_increment primary key,
dispatch_date datetime,
return_date datetime,
bonus int,
code_driver int not null, foreign key (code_driver) reference (id_driver),
code_route int not null, foreign key (code_route) reference (id_route))
type=InnoDB;

mysql> create table work_done (
    ->  id_work int not null auto_increment primary key,
    ->  dispatch_date datetime,
    ->  return_date datetime,
    ->  bonus int,
    ->  code_driver int not null, foreign key (code_driver) reference (id_driver
),
    ->  code_route int not null, foreign key (code_route) reference (id_route))
    ->  type=InnoDB;
Выдается такая ошибка
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that

id_driver и id_route - первичные ключи из других таблиц в этой же базе данных.
как вбить правильно?
