Question

我有一个使用c＃和SQL Server 2005进行时间和考勤的应用程序。在SQL中，我创建了一个包含3个参数的存储过程。

事件表是这样的：

UnitTS          RdrName          RdrIn_Out    CrdName

201401030759    Office1             B        Mike             
201401030819    Office2             B        Alex           
201401030944    Office2             B        Alex             
201401030947    Office2             B        Tomy             
201401030955    Office3             B        John           
201401030955    Office3             A        John          
201401031015    Office1             B        Alex                   
201401031034    Office1             A        Alex                   
201401031457    Office1             B        Alex                
201401031626    Office1             A        Alex                 
201401031649    Office2             B        Janina                 
201401031727    Office2             B        Janina

执行存储过程后，我得到以下结果：

CrdName|RdrName  | Date  | In_Time | Out_Time | Duration

Alex    Office 1  03-01-2014 09:35   09:41       360
Alex    Office 1  03-01-2014 unknown 09:41        0
Alex    Office 1  03-01-2014 14:58   14:59       60
Alex    Office 1  03-01-2014 unknown 14:59        0

这是查询

   @Emp nvarchar(50),
   @Start_Date nvarchar(50),
   @End_Date nvarchar(50)
as
   with Ordered as 
   ( select 
       convert(varchar(15), cast(Substring(unitts,1,8) as DATE), 105 ) as Data, 
       Substring(UnitTS,9,2)+':'+ Substring(UnitTS,11,2) as EventTime,
           case when RdrHead = 'A' THEN 'OUT' ELSE 'IN 'END as Reader,
           [RdrName],
           [CrdName],
           rn = row_number() over (order by RdrName)
    from 
        Time.dbo.History 
    where 
        (UnitNr = '3' and RdrNr IN ('0','2','3') OR UnitNr = '4' and RdrNr IN('1','6')) 
        and Type = 'A' 
        and Substring(unitts, 1, 8) >= @Start_Date 
        and Substring(unitts, 1, 8) <= @End_Date and (CrdName in (@emp) or @emp= 'all')
)
select
    o_out.CrdName,
    o_out.RdrName,
    o_out.Data,
    case when o_in.EventTime is null then 'unknown' else o_in.EventTime end In_Time,
    [Out_Time] = o_out.EventTime ,
    case when cast(datediff (s,o_in.EventTime ,o_out.EventTime) AS int) is null then '0' ELSE cast(datediff (S,o_in.EventTime ,o_out.EventTime) as int) END Duration
from Ordered o_out
 left join Ordered o_in
   on o_in.rn = o_out.rn - 1
  and o_in.Reader ='in'
where o_out.Reader= 'out'

如果我想选择一个CrdName，代码就可以了。问题是当我想要选择所有CrdName时。结果不正确。我尝试按CrdName订购数据，但没有结果。

我想，我需要通过UnitTS，RdrName和CrdName以某种方式订购Events表

有什么解决方案吗？谢谢
