Question

我想从会员IP获取位置。我可以在phpmyadmin上使用该命令，它的成本约为2秒。但是当通过终端在MySQL上执行命令时它会被卡住。我该如何解决这个问题。

SQL命令：

SELECT 
    ID,country 
FROM 
    (SELECT ID,substring_index(members.server_ids,',',1) AS IP FROM members) AS A 
JOIN 
    (SELECT country,start,end FROM ip) AS B 
ON 
    INET_ATON(A.IP) BETWEEN INET_ATON(B.start) AND INET_ATON(B.end);

phpMyAdmin会自动为查询添加LIMIT子句。因为您没有ODER BY子句，所以MySQL会在找到您在LIMIT子句中请求的记录数后立即发送结果。

将LIMIT子句添加到您在命令行上执行的查询。

在终端上运行的MySQL命令卡住了，但是phpmyadmin成功了
