当我尝试导入 mysql 备份文件时,我收到这样的错误,
ALTER TABLE `sf_guard_group_permission` ADD CONSTRAINT `sf_guard_group_permission_FK_1` FOREIGN KEY ( `group_id` ) REFERENCES `sf_guard_group` ( `id` ) ON DELETE CASCADE ,
ADD CONSTRAINT `sf_guard_group_permission_FK_2` FOREIGN KEY ( `permission_id` ) REFERENCES `sf_guard_permission` ( `id` ) ON DELETE CASCADE ;
MySQL zwrócił komunikat: Dokumentacja
#1005 - Can't create table 'jezykownia.#sql-1394_72' (errno: 121)
虽然一切似乎都很好,但我有点害怕未来可能会出现什么后果
提前致谢:)
