第一步：查看数据

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）

第七步：回复数据

方法一：在数据外面回复

[root@zxw66 ~]#  mysql -uroot -p123 zxw < 6bin.sql 
Warning: Using a password on the command line interface can be insecure.
ERROR 1064 (42000) at line 10022: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''/*!*/;

#190831 10:08:28 server id 1  end_log_pos 137813 CRC32 0x81f' at line 1

方法二：在数据里回复

mysql> source 6bin.sql

　　

第八步：再次查看数据
