3，插入数据，并删除表
mysql> insert into t values(3);
Query OK, 1 row affected (0.01 sec)
mysql> insert into t values(4);
Query OK, 1 row affected (0.00 sec)
mysql>
mysql>
mysql>
mysql> drop table t;
Query OK, 0 rows affected (0.01 sec)
4，查看当前binlog位置，并得到删除操作的位置

5，安全起见，在生产中最好在测试库上做恢复，此处我直接在本机恢复

mysql>
mysql> drop database testdb;
