外鍵

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; 

但還是WHN刪除級聯我一個從tbl_business含有包括從tbl_businessalbum的外鍵關係，即數據的行刪除記錄不會被刪除

Answer 1

有人糾正我，如果我是過時，但MySQL MyISAM引擎不處理外鍵呢？
