Question

我需要计算某个范围之间的记录，但从长远来看，例如：我参加范围＆＃39; 2014-07-01＆＃39;和＆＃39; 2014-07-21＆＃39;，但我只在21:00:00到21:30:00之间需要记录......

Count(records) between '2014-07-01 21:00:00' and '2014-07-01 21:30:00'
Count(records) between '2014-07-02 21:00:00' and '2014-07-02 21:30:00'
...

谢谢！

Answer 1

您可以尝试这样：

SELECT COUNT(records)
FROM [yourtable]
WHERE [timestamp] BETWEEN '2014-07-01' AND '2014-07-02'
  AND CONVERT(TIME, [timestamp]) BETWEEN '21:00:00' AND '21:30:00'

如何在t-sql的时间范围内占用更长的时间范围
