mysql 查看binlogformat_mysqlbinlog 查看具体的sql语句 (binlog_format=row模式)

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';
