MySQL 8.4中的唯一外键问题
Recently, a friend reached out to me for help after encountering an error while restoring a MySQL dump during an upgrade from MySQL 8.0 to 8.4. The error read: At… The post A Unique Foreign Key...
最近，一位朋友在将MySQL从8.0升级到8.4时遇到外键约束错误，提示缺少唯一键。MySQL 8.4开始强制要求外键引用唯一或主键列。建议临时关闭此限制，但应遵循标准外键定义以确保兼容性。
