SQL Server中的特定时间范围查询 [英] Specific Time Range Query in SQL Server

问题描述

我正在尝试查询特定的时间范围：

I'm trying to query a specific range of time:

• 即。 3/1/2009 - 3/31/2009


• 每天上午6点到10点之间


• 周二/周三/周四

我已经看到你可以获取特定范围的数据，但只能从头到尾，这更具体一些。我没有看到任何直接帮助我的SQL Server命令，还有其他人有什么想法可以形成这个吗？

I've seen that you can get data for a particular range, but only for start to end and this is quite a bit more specific. I didn't see any SQL Server commands that would directly help me on this, so does anybody else have any thoughts on how you would form this?

我已经看过这个，但我认为这不足够

I've seen this, but I don't think it's nearly specific enough for this range.

谢谢！

推荐答案

我假设你想要所有这三个作为选择标准的一部分。你需要在你的位置提供几个陈述，但它们将与您的问题所在的链接相似。

I'm assuming you want all three of those as part of the selection criteria. You'll need a few statements in your where but they will be similar to the link your question contained.

SELECT *
  FROM MyTable
  WHERE [dateColumn] > '3/1/2009' AND [dateColumn] <= DATEADD(day,'3/31/2009',1) 
                 --make it inclusive for a datetime type
    AND DATEPART(hh,[dateColumn]) >= 6 AND DATEPART(hh,[dateColumn]) <= 22 
                 -- gets the hour of the day from the datetime
    AND DATEPART(dw,[dateColumn]) >= 3 AND DATEPART(dw,[dateColumn]) <= 5 
                 -- gets the day of the week from the datetime
