Question

我们有例如。下表

| ID | startDateTime       | endDateTime         |
+----+---------------------+---------------------|
|  1 | 2010-01-01 10:30:00 | 2010-01-01 11:00:00 |
|  2 | 2010-01-01 10:30:00 | 2010-01-01 11:30:00 |
|  3 | 2010-01-01 11:00:00 | 2010-01-01 11:30:00 |
|  4 | 2010-01-01 11:00:00 | 2010-01-01 12:00:00 |
|  5 | 2010-01-01 11:30:00 | 2010-01-01 12:00:00 |
|  6 | 2010-01-01 10:30:00 | 2010-01-01 12:00:00 |

我会...用

查询

@startDateTime 2010-01-01 11:00:00
@endDateTime 2010-01-01 11:30:00

我想获得以下ID：2,3,4,6

我的大脑是古怪的，以产生正确的陈述...... :(

你可以这样做

declare @T table (ID int, startDateTime datetime, endDateTime datetime)

insert into @T values
(  1 , '2010-01-01 10:30:00' , '2010-01-01 11:00:00'),
(  2 , '2010-01-01 10:30:00' , '2010-01-01 11:30:00'),
(  3 , '2010-01-01 11:00:00' , '2010-01-01 11:30:00'),
(  4 , '2010-01-01 11:00:00' , '2010-01-01 12:00:00'),
(  5 , '2010-01-01 11:30:00' , '2010-01-01 12:00:00')

declare @startDateTime datetime
declare @endDateTime datetime


set @startDateTime = '2010-01-01 11:00:00'
set @endDateTime = '2010-01-01 11:30:00'

select *
from @T
where
  startDateTime < @endDateTime and
  endDateTime > @startDateTime
