これが私が現在使用しているクエリです。

SELECT [EmpNumber], [TimeStamp], [AreaName], 
    DATEDIFF(second, [TimeStamp], (SELECT TOP 1 [TimeStamp] 
                                   FROM [EventTable] EV2 
                                   WHERE EV2.[TimeStamp] > EV1.[TimeStamp] 
                                   AND AreaName = 'OUT_1' 
                                   AND EV2.[EmpNumber] = EV1.[EmpNumber])
            )/60.00 DurationMins 
FROM [EventTable] EV1 
WHERE AreaName = 'IN_1' 
ORDER BY [TimeStamp] DESC

問題は複数のIN_1エントリにあります。IN_1最初のエントリと次のエントリの時間差のみを追跡し、その間のOUT_1エントリを無視しIN_1ます。もちろん、100を設定することもできますが、時間は最初から次IN_1の時間までしか追跡されません。IN_1OUT_1

さらに複雑にするために、、、、、、があり、出入りすることIN_1ができIN_2、それはそのまま機能します。IN_3OUT_1OUT_2OUT_3IN_1OUT_3IN_1OUT_1

select g.empnumber, min(g.[timestamp]) as starttime, g.[timeout] as endtime, DATEDIFF(second,min(g.[timestamp]),g.[timeout])/60 as mins
FROM
(
select empnumber, [timestamp], (
 SELECT TOP 1 s.[timestamp] FROM @test s
   WHERE  s.areaname like 'OUT%' AND s.[timestamp] > base.[timestamp]
   ORDER BY s.[timestamp] ASC) as [timeout] 
from @test base
where base.areaname like 'IN%'
) g
GROUP BY g.empnumber, g.[timeout]

次の結果が得られます。

IN_ および OUT_ の場合、これはすべてのタイプで機能します。
