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,当我从tbl_business删除记录时,包含外键关系中涉及的数据的行,即来自tbl_businessalbum的行不会被删除
答案 0 :(得分:4)
有人纠正我,如果我已经过时了,但MySQL MyISAM引擎不处理外键吗?
