Mysql 返回一个包含组_CONCAT的单行

我的查询有问题，我想将所有会计数据分组在一起，并对客户的站点名称和站点IP进行分组

我使用了

GROUP_CONCAT（site_name）作为site_name

和

GROUP_CONCAT（site_ip）作为site_ip

，但我得到的结果仍然不正确，并且在GROUP_CONCAT列中得到了重复的ip

我需要为每个客户机提供一行数据，其中包含属于他们的每个站点IP的计算流量总和/分组

我的问题是：

我当前的结果如下所示：

您应该按照非聚合列（而不是聚合函数中使用的列）进行分组，例如：

我看得出你不明白我的意思。。。因为您误用了MySQL的GROUP BY方法，这将导致无效结果。。我建议你们阅读这篇（）的旧文章，但它至今仍然有效。我现在更困惑了。如果我删除组_CONCAT，一切正常，但随后返回多个行，每个客户机具有相同的数据，但具有不同的站点信息，如带宽使用情况、站点名称、站点IP等。我想做的就是合并这些行，并为

站点名称

和

站点ip

列提供逗号，以及属于每个客户端的每个站点的所有带宽使用量之和。如果你说我不正确地使用GROUP BY，那么你能告诉我应该做什么吗如果没有示例数据和预期输出，这很难说。我刚刚说了我的预期输出需要是什么：我想做的就是合并行，并为site_name和site_ip列提供逗号，以及属于每个客户端的每个站点的所有带宽使用量之和，但当您提供示例数据。。我们不是来对您的SQL查询进行反向工程的。我仍然在结果中获得重复的

站点名称

和

站点IP

“我仍然在结果中获得重复的站点名称和站点IP”，您可以在函数组中使用DISTINCT。。像这样

GROUP\u CONCAT（不同的站点名称）作为站点名称
