表1:
emp_id in_time out_time
9999 2018-10-21 08:00:00.000 2018-10-22 06:00:00.000
9999 2018-10-22 06:00:00.000 2018-10-22 07:00:00.000
9999 2018-10-23 19:00:00.000 2018-10-24 07:00:00.000
表2:
select a.emp_reader_id, DT, EVENTID1
from trnevents a
left outer join daily_attendance_data d on d.emp_reader_id = a.emp_reader_id
left outer join employee e on e.emp_reader_id = a.emp_reader_id
where (CONVERT(VARCHAR(26), A.DT, 23) >= CONVERT(VARCHAR(26), '2018-10-23', 23)
and CONVERT(VARCHAR(26), A.DT, 23) <= CONVERT(VARCHAR(26), '2018-10-24', 23))
and a.emp_reader_id=9999
group by a.emp_Reader_id, a.dt,a.eventid
order by emp_reader_id, DT asc
我尝试通过该查询从table2的intime和outtime之间获取table1中的所有数据,但是我无法在这些in_time和out_time之间获取
2018-10-23 19:00:00.000
2018-10-24 03:00:00.000
2018-10-24 05:00:00.000
2018-10-24 07:00:00.000
预期输出: in_time:2018-10-23 19:00:00.000 out_time:2018-10-24 07:00:00.000

如果DT是日期时间,则在此条件下工作无需任何varchar转换
where DT>='2018-10-23 19:00:00.000' and DT<='2018-10-24 07:00:00.000'
