binlog_format=row的情况下： 
对delete的内容，通过 mysqlbinlog找到 真实的delete语句， 也可以通过这种方法 ，构成一个insert语句，然后回滚这个操作 
binlog_format=statement是不行的。 

例： 
mysql> show variables like '%binlog_format%' 
-> ; 
+---------------+-------+ 
| Variable_name | Value | 
+---------------+-------+ 
| binlog_format | ROW | 
+---------------+-------+ 
1 row in set (0.00 sec) 


mysql> delete from test where c1=1; 
Query OK, 1 row affected (0.00 sec) 

mysql> commit; 
Query OK, 0 rows affected (0.00 sec) 

mysql> flush tables; 
Query OK, 0 rows affected (0.00 sec) 

mysql> flush logs; 
Query OK, 0 rows affected (0.03 sec) 

然后通过mysqlbinlog去解析文件： 

[mysql@localhost data]$ mysqlbinlog --base64-output=DECODE-ROWS -vvv 1.000001

如果是 binlog_format=statement的话，得到的结果是 
use `test`/*!*/; 
SET TIMESTAMP=1427360555/*!*/; 
delete from test where c1=4 
/*!*/;

不能重构出来原来的insert
