ERROR 1025 (HY000): Error on rename of '.\test\#sql-c68_10' to '.\test\member' (errno: 150)

将member表id键改为bigint:alter table member modify column id BIGINT;

执行时发现如下错误：

ERROR 1025 (HY000): Error on rename of '.\test\#sql-c68_10' to '.\test\member' (errno: 150)

原因：

member表的id主键字段是另外一张address的外键，修改主表id字段类型会导致主表与外键关联表字段不一致。

解决方法：

1. 找到外键关联表，找到外键名字。
2. 删除外键约束
3. 修改主表(member)id字段类型:alter table member modify column id bigint;
4. 修改辅表(address)member_id字段类型:alter table address modify column member_id bigint;
5. 将删除的外键补上:alter table address add constraint fk_member_address foreign key (member_id) references member(id);
