删除外键：

alter table `itrip_shop` drop FOREIGN KEY `FK_ayixnihiit0pouq70l8ig0ax9`;


删除唯一键：

alter table `itrip_shop` drop index `UK_ayixnihiit0pouq70l8ig0ax9`;


添加外键约束（复杂选项版）：

alter table `itrip_shop` ADD CONSTRAINT `FK_ayixnihiit0pouq70l8ig0ax9` FOREIGN KEY `FK_ayixnihiit0pouq70l8ig0ax9` (`shop_admin`) REFERENCES `itrip_user` (`user_id`);
