[Вопрос] (error #1005) Can't create table 'newdb.business' (errno: 150)

При создании таблицы, выдаёт ошибку как в заголовке.
Таблица accounts так-же на движке InnoDB. Что может быть не так?

mysql_tquery(mysql, "\
        CREATE TABLE IF NOT EXISTS `business` (\
        `business_id` int(9) NOT NULL,\
        `business_type` int(3) NOT NULL,\
        `business_owner` varchar(25) NOT NULL DEFAULT 'Unknown',\
        `business_owner_id` int(11) NOT NULL DEFAULT '-1',\
        PRIMARY KEY (`business_id`),\
        CONSTRAINT `account_business_fk`\
        FOREIGN KEY (`business_owner_id`,`business_owner`) REFERENCES accounts (`ID`,`ID`) ON DELETE SET DEFAULT,\
        CONSTRAINT `account_business_fk_2`\
        FOREIGN KEY (`business_owner`) REFERENCES accounts (`Name`) ON UPDATE CASCADE\
        ) ENGINE=InnoDB DEFAULT CHARSET=cp1251;\
    ");
