    这是一个创建于 393 天前的主题,其中的信息可能已经有所发展或是发生改变。

    搞了一下午了,没搞出来,来求助万能的 V 友了
    列 src_ip 类型是 binary(16)

    mysql> desc X20180327;
    +--------------+----------------------+------+-----+---------+----------------+
    | Field        | Type                 | Null | Key | Default | Extra          |
    +--------------+----------------------+------+-----+---------+----------------+
    | auto_id      | int(10) unsigned     | NO   | MUL | NULL    | auto_increment |
    | record_id    | int(10) unsigned     | NO   | PRI | NULL    |                |
    | src_zone     | int(10) unsigned     | NO   |     | NULL    |                |
    | src_ip       | binary(16)           | NO   | MUL | NULL    |                |
    | src_port     | smallint(5) unsigned | NO   |     | NULL    |                |
    | dst_zone     | int(10) unsigned     | NO   |     | NULL    |                |
    | dst_ip       | binary(16)           | NO   | MUL | NULL    |                |
    | dst_port     | smallint(5) unsigned | NO   |     | NULL    |                |
    

    存储方式如下:
    首字节存储非法 IPv6 头,后 4 字节存储 ipv4 数值,其他字节填充 0,网络序存储

    mysql> select HEX(src_ip) from FW_LOG_fwlog.X20180327 where auto_id = 1;
    +----------------------------------+
    | HEX(src_ip)                      |
    +----------------------------------+
    | FFBF000000000000000000007BF94C7D |
    +----------------------------------+
    1 row in set (0.00 sec)
    

    我单独把值复制出来转换时没问题的

    mysql> select inet_ntoa(0xFFBF000000000000000000007BF94C7D & 0xFFFFFFFF) from FW_LOG_fwlog.X20180327 where auto_id = 1;
    +------------------------------------------------------------+
    | inet_ntoa(0xFFBF000000000000000000007BF94C7D & 0xFFFFFFFF) |
    +------------------------------------------------------------+
    | 123.249.76.125                                             |
    +------------------------------------------------------------+
    1 row in set (0.00 sec)
    
    mysql> select inet_ntoa(0xFFBF000000000000000000007BF94C7D) from FW_LOG_fwlog.X20180327 where auto_id = 1;
    +-----------------------------------------------+
    | inet_ntoa(0xFFBF000000000000000000007BF94C7D) |
    +-----------------------------------------------+
    | 123.249.76.125                                |
    +-----------------------------------------------+
    1 row in set (0.00 sec)
    
    mysql> select inet_ntoa(0x7BF94C7D);
    +-----------------------+
    | inet_ntoa(0x7BF94C7D) |
    +-----------------------+
    | 123.249.76.125        |
    +-----------------------+
    1 row in set (0.00 sec)
    

    但是………………

    mysql> select INET_NTOA(src_ip) from FW_LOG_fwlog.X20180327 where auto_id = 1;
    +-------------------+
    | INET_NTOA(src_ip) |
    +-------------------+
    | 0.0.0.0           |
    +-------------------+
    1 row in set, 1 warning (0.00 sec)
    mysql> select inet_ntoa(src_ip&0xFFFFFFFF) from FW_LOG_fwlog.X20180327 where auto_id = 1;
    +------------------------------+
    | inet_ntoa(src_ip&0xFFFFFFFF) |
    +------------------------------+
    | 0.0.0.0                      |
    +------------------------------+
    1 row in set, 1 warning (0.00 sec)
    
    mysql> show warnings;
    +---------+------+-----------------------------------------+
    | Level   | Code | Message                                 |
    +---------+------+-----------------------------------------+
    | Warning | 1292 | Truncated incorrect INTEGER value: '??' |
    +---------+------+-----------------------------------------+
    1 row in set (0.00 sec)
    

    该怎么处理呢? 版本:Ver 14.14 Distrib 5.1.58

    试试 cast src_ip 到 interger 再运算。

    哈哈哈,我刚搞定,想法差不多

    mysql> select inet_ntoa(conv(right(HEX(src_ip),8),16,10))
    from FW_LOG_fwlog.X20180327 limit 100;
    +---------------------------------------------+
    | inet_ntoa(conv(right(HEX(src_ip),8),16,10)) |
    +---------------------------------------------+
    | 1.31.58.142 |
    | 14.204.67.143 |
    | 14.204.126.70 |
    | 27.156.89.140 |
    | 37.187.148.221 |

    虽然这样有点恶心………………行了就这样吧,谢谢啦兄弟!
