删除外键级联

Question

CREATE TABLE IF NOT EXISTS `tbl_businessalbum` 
(
`id` bigint(20) unsigned NOT NULL AUTO_INCREMENT,
`image` varchar(50) NOT NULL,
`businessId` bigint(20) unsigned NOT NULL,
`addedBy_userId` bigint(20) unsigned DEFAULT NULL,
`date` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
PRIMARY KEY (`id`),
CONSTRAINT fk_businessId FOREIGN KEY(businessId) REFERENCES tbl_business(id) 
ON DELETE CASCADE
) ENGINE=MyISAM  DEFAULT CHARSET=latin1;

但是，即使我从tbl_business中删除一条记录，包含与外键关系有关的数据的行（即从tbl_businessalbum中删除）也不会被删除

Answer 1

如果我已经过时，可以有人纠正我，但是MySQL MyISAM引擎不处理外键吗？
