第二步：删除表
mysql> delete from zxw.xiaoshou;
Query OK, 33 rows affected (0.01 sec)
第三步：查看数据
mysql> select * from xiaoshou;
Empty set (0.00 sec)
第四步：不小心删除表，不要慌，首先查看二进制文件
mysql> show master statusG
*************************** 1. row ***************************
File: bin.000006 这个是二进制文件目录
Position: 137813
Binlog_Do_DB:
Binlog_Ignore_DB:
Executed_Gtid_Set:
1 row in set (0.00 sec)
第五步：导出二进制文件到/root下下面
[root@zxw66 ~]# mysqlbinlog /var/lib/mysql/bin.000006 > /root/6bin.sql
第六步：修改导出的二进制文件
[root@zxw66 ~]# vim 6bin.sql
查找到删除语句
/Delete
按一下G跳转到最后
在按一下N （N是从后往前高亮查找）
把delete的语句删除（圈起来的都删除）
