Sql server Sql Server：每十分钟计数一次记录（包括零）
我目前有一个表（SQLServer2005），记录我的web应用程序的访问，我想整理一些代码来报告（并显示可视化）流量。我想要的是显示过去24小时内每十分钟的访问次数 我有一个查询就是这样做的，但是有十分钟的时间间隔，在此期间没有访问，我想调整我的查询以显示这些时间间隔的零计数。我想我可以想出一些使用游标的方法，但如果我能避免的话，我宁愿不使用它们 以下是到目前为止的查询：Sql server Sql Server：每十分钟计数一次记录（包括零）,sql-server,sql-server-2005,Sql Server,Sql Server 2005,我目前有一个表（SQLServer2005），记录我的web应用程序的访问，我想整理一些代码来报告（并显示可视化）流量。我想要的是显示过去24小时内每十分钟的访问次数 我有一个查询就是这样做的，但是有十分钟的时间间隔，在此期间没有访问，我想调整我的查询以显示这些时间间隔的零计数。我想我可以想出一些使用游标的方法，但如果我能避免的话，我宁愿不使用它们 以下是到目前为止的查询： DECLARE @time int DECLARE @interval int SELECT @time=96 SELEC

谢谢 实现这一点的简单方法是使用CTE并创建一个具有开始时间间隔的帮助表，然后在主查询中使用between连接到该表 这有意义吗？稍后我将编写一些示例代码
