Mysql 如何将复制数据值分组到我的脚本

这是我的脚本的结果，任何人都可以在此日期前帮助分组。如图所示，每个计数器有4行。

MYSQL不允许按特定列区分结果-distinct只能应用于整行，以便返回唯一的行。重复生效日期，因为生效日期、计数器_1、计数器_2、计数器_3和计数器_4的每个新组合都被视为一个不同的行

以上使用group by effectiveDate是否为您提供了所需信息

上述使用group by effectiveDate是否提供了所需信息？

请注意，DISTINCT不是一个函数。请看，您能否提供一个文本示例，说明输出应该是什么样的？通常helps@stombeur用户的日志应在组中。@stomber示例7:00:00---12:00:00---13:00:00---17:00:00，并且生效日期不应重复。正如您可以看到许多日期的输出。@JobertJayJaducana，您可以从问题中删除标记tsql（特定于Microsoft SQL Server的SQL）吗？在我看来，您提出的问题似乎与查询mysql数据库有关，而不是Microsoft SQL Server。请注意，DISTINCT不是一个函数。请看，您能否提供一个文本示例，说明输出应该是什么样的？通常helps@stombeur用户的日志应在组中。@stomber示例7:00:00---12:00:00---13:00:00---17:00:00，并且生效日期不应重复。正如您可以看到许多日期的输出。@JobertJayJaducana，您可以从问题中删除标记tsql（特定于Microsoft SQL Server的SQL）吗？在我看来，您提出的问题似乎与查询mysql数据库有关，而不是Microsoft SQL Server。
