我需要计算以分钟计的重叠机器运行时间的数量。是否需要这样做？有滞后还是导致？或者我用子查询来做？我在SQL Server 2016上工作。计算重叠分钟的数量

什么是重叠的情况？请添加预期结果。 –

重叠条件停止值条目>起始值下一条目 –

查看条目2和3。他们平行运行。 –

您可以使用此查询。我从停止时间减去重叠的开始时间。

DECLARE @Tbl TABLE(Start DATETIME, [Stop] DATETIME,Machine VARCHAR(20),Prodid VARCHAR(20)) 

INSERT INTO @Tbl VALUES 

('2017-09-11 06:36:37.000','2017-09-11 07:41:35.000','CNC M 6','17-012811'), 
('2017-09-11 07:49:27.000','2017-09-11 10:10:01.000','CNC M 6','17-012811'), 
('2017-09-11 09:34:46.000','2017-09-11 10:10:01.000','CNC M 7','17-012738'), 
('2017-09-11 10:14:50.000','2017-09-11 11:50:15.000','CNC M 6','17-012811'), 
('2017-09-11 10:15:50.000','2017-09-11 11:50:15.000','CNC M 7','17-012738'), 
('2017-09-11 11:55:52.000','2017-09-11 12:17:03.000','CNC M 6','17-012811'), 
('2017-09-11 11:56:15.000','2017-09-11 12:17:14.000','CNC M 7','17-012738') 

SELECT T1.*, DATEDIFF(MINUTE, Ovr.Start , T1.[Stop]) Overlapping FROM @Tbl T1 
OUTER APPLY (SELECT TOP 1 * FROM @Tbl T2 WHERE T2.Start > T1.Start AND T2.Start < T1.Stop ORDER BY T2.Start)) AS Ovr

结果

Start     Stop     Machine    Prodid    Overlapping

谢谢，这将有助于 –

不客气！为了解决这个问题，你可以标记为正确的吗？ –

Sarslan Ovr.Start是什么意思？ –
