Question

我想基于相同的位置和相同的日期添加到第一个值checkin和最后一个值checkout。

我运行此查询：

 select USERID , CHECKTIME , SENSORID 
 from CHECKINOUT
 where USERID = 15

我的意思是：

USERID  CHECKTIME           SENSORID 
------------------------------------
15  2014-10-20 01:22:01.000 100
15  2014-10-20 12:38:22.000 100
15  2014-10-20 22:00:54.000 100
15  2014-10-21 01:24:30.000 100
15  2014-10-21 07:31:39.000 100
15  2014-10-21 22:11:47.000 100
15  2014-10-22 00:10:34.000 100
15  2014-10-22 05:51:47.000 100

是：

USERID  CHECKTIME                   SENSORID 
---------------------------------------------
15  2014-10-20 01:22:01.000-checkin     100
15  2014-10-20 12:38:22.000-checkout    100
15  2014-10-20 22:00:54.000-checkin     100
15  2014-10-21 01:24:30.000-checkin     100
15  2014-10-21 07:31:39.000-checkout    100
15  2014-10-21 22:11:47.000-checkin     100
15  2014-10-22 00:10:34.000-checkin     100
15  2014-10-22 05:51:47.000-checkout    100

但基于sensorid的日期相同且相同。

Answer 1

尝试这样

select USERID,CHECKTIME + case when code % 2 =0 then '- Check out' 
else ' -Check IN' end,SENSORID from (
 select *,ROW_NUMBER() over(PARTITION BY USERID,CHECKTIME 
                          order by USERID ,CHECKTIME) code 
from table1) as t1

Answer 2

试试这个，这可以帮到你：

select userid,convert(varchar(30),checktime,121) +
       case when 
       ((row_number() over (partition by userid,sensorid,convert(varchar(30),checktime,101)
                            order by checktime))%2 = 0) 
        then '-checkout' 
        else '-checkin' end
        as checktime,sensorid
from temt
where userid = 15

here是demo sql fiddle

如果您想添加一个包含值的新列，则可以使用以下解决方案：

alter table temt 
add   checkinorout varchar(50) 
;with cte_update (userid,checkinorout,ctime,sensorid) as
(
  select userid,checkinorout,convert(varchar(30),checktime,121) +
         case when 
         ((row_number() over (partition by userid,sensorid,convert(varchar(30),checktime,101)
                              order by checktime))%2 = 0) 
          then '-checkout' 
          else '-checkin' end
  as ctime,sensorid
  from temt
)
update cte_update set checkinorout = ctime 


select * from temt

根据另一个值设置SQL值？
