Données:
EmpNumber, TimeStamp, AreaName 10632, 2009-11-23 16:40:33.000, OUT_1 10632, 2009-11-23 16:39:03.000, IN_1 10632, 2009-11-23 16:38:56.000, IN_1 10632, 2009-11-23 15:31:51.000, OUT_1 10632, 2009-11-23 15:31:48.000, IN_1 10632, 2009-11-23 15:31:43.000, IN_1 10632, 2009-11-23 15:31:14.000, OUT_1 10632, 2009-11-23 15:31:08.000, IN_1 10632, 2009-11-23 15:29:18.000, OUT_1 10632, 2009-11-23 15:28:29.000, IN_1 10632, 2009-11-23 15:27:35.000, OUT_1 10632, 2009-11-23 15:26:35.000, IN_1 10632, 2009-11-23 15:22:55.000, IN_1
Voici la requête que je utilise actuellement.
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
Le problème est sur les multiples entrées de IN_1. Je voudrais seulement suivre la différence de temps entre la première entrée IN_1, et l'entrée de OUT_1 Suite et ignorer l'entrée de IN_1 entre les deux. Bien sûr, vous pourriez avoir 100 IN_1 mais le temps est seulement suivi de la première IN_1 à l'autre OUT_1.
Pour compliquer encore les choses, il pourrait être un IN_1, IN_2, IN_3, OUT_1, OUT_2, OUT_3 et vous pouvez entrer IN_1 et laisser OUT_3 et il travailleraient tout comme il était IN_1, OUT_1.

declare @test table (

timestamp datetime,
areaname varchar(20)
)
INSERT INTO @test VALUES (1, 10632, '2009-11-23 16:40:33.000', 'OUT_1' )
INSERT INTO @test VALUES (2, 10632, '2009-11-23 16:39:03.000', 'IN_1' )
INSERT INTO @test VALUES (3, 10632, '2009-11-23 16:38:56.000', 'IN_1' )
INSERT INTO @test VALUES (4, 10632, '2009-11-23 15:31:51.000', 'OUT_1' )
INSERT INTO @test VALUES (5, 10632, '2009-11-23 15:31:48.000', 'IN_1' )
INSERT INTO @test VALUES (6, 10632, '2009-11-23 15:31:43.000', 'IN_1' )

INSERT INTO @test VALUES (12, 10632, '2009-11-23 15:26:35.000', 'IN_1' )
INSERT INTO @test VALUES (13, 10632, '2009-11-23 15:22:55.000', 'IN_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]
donne ces résultats:
empnumber starttime endtime mins
10632 2009-11-23 15:22:55.000 2009-11-23 15:27:35.000 4
10632 2009-11-23 15:28:29.000 2009-11-23 15:29:18.000 0
10632 2009-11-23 15:31:08.000 2009-11-23 15:31:14.000 0
10632 2009-11-23 15:31:43.000 2009-11-23 15:31:51.000 0
10632 2009-11-23 16:38:56.000 2009-11-23 16:40:33.000 1
Cela fonctionne pour tous les types si IN_ et OUT _
Autres conseils
Nick, les différentes portes ne sont pas un problème au lieu d'utiliser = 'IN_1' et = 'OUT_1' like 'IN%' et l'utilisation de like 'OUT%'
