Question

我在表格中有以下内容

--2,4,1| 2016-02-21 10:22:00 | 2016-02-21 12:22:00 --

即id's(varchar)，fromtime(datetime)和totime(datetime)

我希望在使用

时返回此ID设置

Select ids 
from Schedule 
where fromtime between '2016/02/21 10:00:00' and '2016/02/21 12:00:00' 
      and totime between '2016/02/21 10:00:00' and '2016/02/21 12:00:00'

但是如果使用此查询

，它会返回空集

Select Participantsids 
from Schedule 
where fromtime between '2016/02/21 10:00:00' and '2016/02/21 13:00:00' 
      and totime between '2016/02/21 10:00:00' and '2016/02/21 13:00:00';

它会返回所需的结果。我需要完全覆盖fromtime和totime以获得我的结果。当我的时间如10:30 - 12时，有办法获得结果：00？

Answer 1

要检查重叠间隔，请使用以下谓词：

SELECT ids 
FROM Schedule 
WHERE fromtime <= '2016-02-21 12:00:00' AND totime >= '2016-02-21 10:00:00'

Answer 2

试试这个

Select Participantsids 
from Schedule 
where fromtime between '2016-02-21 10:00:00' and '2016-02-21 13:00:00' 
and totime between '2016-02-21 10:00:00' and '2016-02-21 13:00:00';
