加入SQL查询 - 无法在IP帮助下为获取国家/地区编写查询

时间：2013-06-21 20:26:50

标签： mysql sql

我有一个访问者列表，其中记录了我的IP。现在，我需要查看每位访客来自哪个国家/地区。

我将此任务分为两部分，首先获取具有唯一登录用户的所有IP，第二部分是搜索具有国家/ IP信息的两个表（来自ip2nation）并获取提供的国家/地区IP

第一部分 - 获取唯一登录的用户的所有IP 

SELECT
     a.uid, a.hostname, a.timestamp, 
 COUNT(*) AS times
FROM
  login_activity a
GROUP BY
  a.hostname
ORDER BY
  times desc

这给了我所有过去登录用户的IP（主机名）。工作正常。

第二部分 - 通过输入IP

从两个表中获取国家（两者都有数千条记录） 
SELECT 
    c.country
FROM 
    ip2nationCountries c, ip2nation i
WHERE 
    i.ip < INET_ATON(  "157.191.122.36" ) 
AND 
    c.code = i.country

ORDER BY i.ip DESC 
LIMIT 0 , 1

这也很有用。

现在，对于真正的问题。加入这两个查询，从所有登录用户获取国家（而不是IP）。这就是我写的： - 

        SELECT
         a.uid, a.hostname, a.timestamp, c.country, 
         COUNT(*) AS times
        FROM
          login_activity a, ip2nationCountries c, ip2nation i
        WHERE
           i.ip < INET_ATON(a.hostname)     
           AND c.code = i.country

        GROUP BY
          a.hostname
        ORDER BY
          times desc;

这有两个问题： -

  • 加载需要很长时间。
  • 它提供了错误的数据（显示每行数千次访问）。
  • 基本上，它显示所有数据都错误。

你能帮我制作这个SQL吗？

以防万一，表格的结构/数据如下： -

表的结构/数据是： -

我按如下方式更改了查询，但仍然显示错误的结果......

你们可以看一下： - 

SELECT l.uid,
    l.hostname,
    l.timestamp,
    c.country,
    l.times
FROM ip2nationCountries c
JOIN ip2nation i ON c.code = i.country
JOIN ( SELECT
        a.uid,
        a.hostname,
        MAX(a.timestamp) AS timestamp,
        COUNT(*) AS times
    FROM mslop_login_activity a
    WHERE a.uid = 3
    AND a.hostname = "157.191.122.36"
    GROUP BY a.hostname) AS l ON i.ip < INET_ATON( l.hostname )

2 个答案:

答案 0 :(得分：0)

您错过了加入。如果您使用正确的连接语法，这将更加明显，因此请将此作为课程，并在将来始终使用join和on子句。

您想要的查询：

    SELECT a.uid, a.hostname, a.timestamp, c.country, COUNT(*) AS times
    FROM login_activity a left outer join
         ip2nationCountries c
         on a.hostname = c.ip left outer join
         ip2nation i
         on i.ip < INET_ATON(a.hostname) AND c.code = i.country
    GROUP BY a.hostname
    ORDER BY times desc;

两条评论。我做了这些left outer join。如果主机名不匹配，则它们仍将显示在输出中（如果要过滤掉这些主机名，请更改为inner join）。其次，在加入其他表之前，您可能希望预先聚合login_activity表，如果它真的很大。

答案 1 :(得分：0)

这将为您提供用户ID，主机名以及他们在该主机上登录的次数。

SELECT a.uid, a.hostname, COUNT(*) AS times
FROM mslop_login_activity a
GROUP BY  a.uid, a.hostname
ORDER BY  times desc

要简化国家/地区，请使用视图计算范围。 （这种观点非常依赖于您获得有关IP地址如何映射到各国的准确完整数据。我没有尝试验证您的数据。）

create view ip_range as 
select t1.ip as ip_start
        , (select min(ip) - 1 from ip2nation where ip > t1.ip) ip_end
        , t1.country
from ip2nation t1

现在你应该可以使用简单明了的联接来获得这个国家。

SELECT a.uid
          , a.hostname
          , inet_aton(a.hostname) as ip_int
          , ip_range.country
FROM mslop_login_activity a
inner join ip_range
on inet_aton(a.hostname) between ip_range.ip_start and ip_range.ip_end

使用您的示例数据，这将不返回任何行。首先，登录活动的所有IP地址都在reserved range。另一方面，“ip2nation”中最长的IP地址（整数）是9位数;这还不够。我自己的IP地址转换为10位整数。

如果我将登录活动中的某个IP地址更新为转换为9位整数的美国IP地址，则上述查询会将该国家/地区正确识别为“US”。

这是您原始查询之一。它没有像你认为的那样做。

SELECT
     a.uid, a.hostname, a.timestamp, 
 COUNT(*) AS times
FROM
  login_activity a
GROUP BY
  a.hostname
ORDER BY
  times desc

返回此行。 

uid  hostname      timestamp  times
--
3    172.24.1.143  1363038356 20

但是这个查询返回12行。请注意，12行不等于20次。

SELECT uid
FROM mslop_login_activity 
where uid = 3

在MySQL中使用GROUP BY是危险的，除非你知道自己在做什么，而且你真的非常小心。 （我不认为任何其他dbms将运行您的原始第一个查询，因为它不符合SQL。）
