我尝试了这个查询，但没有得到如上所述的确切输出：

SELECT Row_number()
     OVER (ORDER BY A.dt ASC)                        AS SNo,
     CONVERT(DATE, A.dt)
   --CONVERT(VARCHAR(26), A.DT, 103)  as DATEEVENT, 
                                                 b.emp_code,
   B.emp_name,
   F.event_entry_name,
   a.dt,
   Cast(LEFT(CONVERT(TIME, a.dt), 5) AS VARCHAR) AS 'time',
   Isnull(B.areaname, 'OAE6080036073000006')     AS areaname,
   C.dept_name,
   b.emp_reader_id,
   Isnull(c.dept_name, '')                       AS group_name,
   CONVERT(CHAR(11), '2017/12/30', 103)          AS StartDate,
   CONVERT(CHAR(11), '2018/01/11', 103)          AS ToDate,
   0                                             AS emp_card_no
FROM   dbo.trnevents AS A
   LEFT OUTER JOIN dbo.employee AS B
                ON A.emp_reader_id = B.emp_reader_id
   LEFT OUTER JOIN dbo.departments AS C
                ON B.dept_id = C.dept_id
   LEFT OUTER JOIN dbo.devicepersonnelarea AS E
                ON A.pointid = E.areaid
   LEFT OUTER JOIN dbo.event_entry AS F
                ON A.eventid = F.event_entry_id

您可以使用子选择或CTE来获取员工订购的数据，并将其用作主数据表。类似的东西（必要时对其进行调整）：

;with ordered as (
select 
    emp_reader_id as empId,
    CONVERT(DATE, dt) as Punch,
    Row_number()
     OVER (PARTITION BY emp_reader_id ORDER BY CONVERT(DATE, dt) ASC) as OrderedPunch
from trnevents
)
SELECT 
    entered.empId, 
    entered.Punch as PunchIn,
    exited.Punch as PunchOut
from
    ordered as entered
    left join ordered as exited on 
        entered.empId = exited.empId
        and entered.OrderedPunch + 1 = exited.OrderedPunch

说明：'ordered'CTE确实显示按日期排序的员工入口/出口。由于ROW_NUMBER，为每个员工重置PARTITION BY（我假设emp_reader_id确实包含员工ID）。

一旦我获得了每个员工的计数器，我就为每个员工加入每个员工（左连接中的第一个条件），并为该员工提供下一个打卡（左连接中的第二个条件）。这样我就可以显示输入栏和出口（下一拳）。

在数据中输入和输出列后，您可能希望排除一些数据（每个员工的奇数行是您想要的行）添加WHERE entered.OrderedPunch %2 = 1

为每位员工全力以赴？
