Question

我正在做考勤系统，以下是我在sql服务器数据库

中的数据

|143    |2017-02-13 |2017-02-13 |20:09:02   |22:38:50   |2.496666000
|143    |2017-02-13 |2017-02-13 |22:59:19   |23:18:15   |0.315555000
|143    |2017-02-13 |2017-02-13 |23:33:47   |05:04:24   |5.510277000
|143    |2017-02-14 |2017-02-13 |02:52:38   |05:12:04   |2.323888000
|143    |2017-02-14 |2017-02-14 |20:09:26   |21:59:27   |1.833611000

-- 我想要这样的输出

|EmpCode|wrk        |InTime     |OutTime    |TotalTime
|143    |2017-02-13 |08:09:02 PM|05:12:04 AM|10:38:00
|143    |2017-02-14 |08:09:26 PM|05:08:13 AM|02:12:00

Answer 1

假设您想要那些特定的时间格式：

rextester：http://rextester.com/FUW31296

create table t (
     EmpCode int
  ,  Date datetime
  ,  WorkDate datetime
  ,  CheckIn datetime
  ,  CheckOut datetime
  ,  TotalTime decimal(19, 9))

insert into t values
 (143,'2017-02-13','2017-02-13','20:09:02','22:38:50',2.496666000)
,(143,'2017-02-13','2017-02-13','22:59:19','23:18:15',0.315555000)
,(143,'2017-02-13','2017-02-13','23:33:47','05:04:24',5.510277000)
,(143,'2017-02-14','2017-02-13','02:52:38','05:12:04',2.323888000)
,(143,'2017-02-14','2017-02-14','20:09:26','21:59:27',1.833611000)
,(143,'2017-02-14','2017-02-14','22:30:10','22:49:26',0.321111000)
,(143,'2017-02-15','2017-02-14','05:05:05','05:08:13',0.052222000);

查询：

select 
     EmpCode
  ,  wrk       = convert(varchar(10),WorkDate,120)
  ,  InTime    = format(cast(min(Date + CheckIn) as datetime), 'hh:mm:ss tt')
  ,  OutTime   = format(cast(max(Date + CheckOut) as datetime), 'hh:mm:ss tt')
  ,  TotalTime = format(dateadd(minute,sum(TotalTime)*60,0), 'HH:mm:ss')
from t
group by 
    EmpCode
  , WorkDate

结果：

+---------+------------+-------------+-------------+-----------+
| EmpCode |    wrk     |   InTime    |   OutTime   | TotalTime |
+---------+------------+-------------+-------------+-----------+
|     143 | 2017-02-13 | 08:09:02 PM | 05:12:04 AM | 10:38:00  |
|     143 | 2017-02-14 | 08:09:26 PM | 05:08:13 AM | 02:12:00  |
+---------+------------+-------------+-------------+-----------+

Answer 2

select EmpCode, WorkDate as wrk, min(InTime) as InTime, max(OutTime) as OutTime, Sum(TotalTime) as TotalTime
from yourtable
group by EmpCode, WorkDate

将为您提供每个用户每天 yourtable 中最小的 InTime、最大的 OutTime 和总计 TotalTime。

Answer 3

select  *
,       datediff(minute, first_in, last_out) as Totaltime
from    (
        select  emp_reader_id
        ,       min(case when Event_entry.event_entry_name = 'IN' then trnevents.DT end) as Intime
        ,       max(case when Event_entry.event_entry_name = 'OUT' then trnevents.DT end) as Outtime
        ,       cast(min(trnevents.DT) as date) as date
        from    trnevents inner join Event_entry on trnevents.EventCatId=Event_entry.EventCatId
        group by
                emp_reader_id
        ,       cast(trnevents.DT as date)
        ) as SubQueriesMustBeNamed
