希望您的意思是仅时间，而不是完整的日期时间(因为那太简单了！)

试试这个:

Hope you meant time only and not full datetime (as that would be too simple!)

Try this:

--Explanation:
--if you have varchar(5) you will obtain HH:mm
--if you have varchar(8) you obtain HH:mm ss
--108 obtains only the time from the SQL date
--@leftTime and @rightTime are two variables to compare
CONVERT(varchar(5), thedate, 108) between @leftTime and @rightTime

另一种执行此操作的方法: http://www.vijaykodali.com/Blog/post/2008/05/14/Comparing-Time-part-in-DateTime-SQL.aspx [ ^ ]


如果需要，您也可以使用DATEPART.
参考: MSDN:DATEPART(Transact-SQL) [ ^ ]

If needed, you can also use DATEPART.
