有什么办法可以回滚吗?
Is there any way to rollback from it?
推荐答案
不，没有查询可以撤消"已提交的数据修改查询.
No, there's no query that will "undo" a committed data-modifying query.
如果你有数据库的备份，你可以恢复备份并使用 DBA 工具(在 MySQL 的情况下，它是 mysqlbinlog) 以重播"自备份回数据库以来日志中的所有数据修改查询，但跳过问题查询.
If you have a backup of the database, you can restore the backup and use DBA tools (in MySQL's case, it's mysqlbinlog) to "replay" all data-modifying queries from the logs since the backup back to the database, but skip over the problem query.
如果您没有备份以及自该备份以来的所有日志，则您无法恢复数据.
If you don't have a backup and all logs since the that backup, there's nothing you can do to recover the data.
