mysqlbinlog 恢复数据到任意时间点

创建表,插入数据.

```

mysql> create database binlog;

mysql> create table bt(id int);

mysql> insert into bi values (1);

mysql> insert into bi values (2);

mysql> insert into bi values (3);

mysql> insert into bi values (4);

mysql> delete from bt where id=1; 误删除

mysql> update bt set id=22 where id=2;

mysql> drop table bt;

mysql> drop database binlog;

```

我想恢复数据到 delete之前

查看当前所有的是哪个binlog
