当binlog_format=row时，用mysqlbinlog想查看二进制日志时需要加上-v参数。

下面分别对比下加-v前与-v后不同的效果：

mysql> use dba;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
mysql> select * from t1;
+----+
| id |
+----+
| 2 |
| 11 |
+----+
2 rows in set (0.00 sec)

mysql> insert into t1(id) values(1);
Query OK, 1 row affected (0.02 sec)

mysql> delete from t1 where id = 11;
Query OK, 1 row affected (0.07 sec)

mysql> show binlog events in 'mysql-bin.000016';
+------------------+-----+----------------+-----------+-------------+--------------------------------------+

一：加-v前
/usr/local/mysql/bin/mysqlbinlog /data/server/mysql_3307/binlog/mysql-bin.000016 > aa.log

插入ID=1的记录对应的二进制日志为（重点关注# at 339下面那行内容即可）：

删除ID=11的记录对应的二进制日志为（重点关注# at 595下面那行内容即可）：

二：加-v后
/usr/local/mysql/bin/mysqlbinlog /data/server/mysql_3307/binlog/mysql-bin.000016 -v > a.log

插入ID=1的记录对应的二进制日志为（重点关注# at 339下面的内容即可）：
