我有 2 个表如下
client_table
date (timestamp)
ip (varchar)
value1 (int)
value2 (int)
ip_address_table
starting_ip (varchar)
ending_ip (varchar)
provider (varchar)
如果 ip 地址在范围内,我正在尝试使用 ip_address_table 表查找 client_table 条目以查找平均每小时。(如果不在范围内,请忽略该行)以下是我想出的
SELECT avg(value1),avg(value2)
FROM client_table
WHERE (INET_ATON(ip) BETWEEN INET_ATON(starting_ip) AND INET_ATON(ending_ip))
GROUP BY DATE(date),HOUR(date)
但是,它没有给出正确的输出。我看了一下http://blog.jcole.us/2007/11/24/on-efficiently-geo-referencing-ips-with-maxmind-geoip-and-mysql-gis/但努力编写存储函数简化任务任何帮助表示赞赏
谢谢
编辑:我的示例数据如下
client_table
"date" "ip" "value1" "value2"
"2012-01-10 06:38:29" "121.1.2.3" "1049" "301"
"2012-01-11 06:41:35" "58.1.2.3" "16453" "794"
"2012-01-12 06:43:50" "101.1.2.3" "1712" "410"
"2012-01-13 06:44:04" "121.1.10.3" "6594" "863"
"2012-01-14 06:45:00" "79.1.2.3" "879" "614"
ip_address_table
"starting_ip" "ending_ip" "provider"
"121.0.0.0" "121.255.255.255" provider1
"79.1.2.0" "79.1.2.255" provider1
....
