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

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
