Question

I want to create a database and connect it with two database. But I don’t know when i create the Foreign Key to the second database (time_shift table) it always result error 150;

Here is the structure of table outlet:

And this is structure of table time_shift:

And this the query to create new table tide_cart:

create table `tide_chart` (
    `id` int(10) not null auto_increment primary key,
    `date` date null,
    `outletId` int(11) not null,
    `timeShiftId` int(11) not null,
    `value` varchar(255) not null,

    unique (`date`, `outletId`, `timeShiftId`),
    foreign key (`outletId`) references `outlet`(`id`) 
        ON update cascade ON delete cascade,
    foreign key (`timeShiftId`) references `time_shift`(`id`) 
        ON update cascade ON delete cascade
) engine=innoDB;

Please explain to me, why i get error when try to make foreign key connect to table time_shift?

Update: add dump export structure table for outlet and time_shift:

CREATE TABLE `outlet` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB  DEFAULT CHARSET=utf8 AUTO_INCREMENT=5 ; 

  CREATE TABLE `time_shift` (
   `id` int(11) NOT NULL AUTO_INCREMENT,
   `time_start` time NOT NULL,
   `time_end` time NOT NULL,
   `is_active` tinyint(4) NOT NULL DEFAULT '1',
   `ref_area` int(11) NOT NULL DEFAULT '1',
   PRIMARY KEY (`id`),
   KEY `ref_area` (`ref_area`)
 ) ENGINE=MyISAM  DEFAULT CHARSET=utf8 AUTO_INCREMENT=7 ;

You need to use the InnoDB engine for your tables. time_shift is using MyISAM.
