我需要計算以分鐘計的重疊機器運行時間的數量。是否需要這樣做？有滯後還是導致？或者我用子查詢來做？我在SQL Server 2016上工作。計算重疊分鐘的數量

什麼是重疊的情況？請添加預期結果。 –

重疊條件停止值條目>起始值下一條目 –

查看條目2和3。他們平行運行。 –

您可以使用此查詢。我從停止時間減去重疊的開始時間。

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 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

結果

謝謝，這將有助於 –

不客氣！爲了解決這個問題，你可以標記爲正確的嗎？ –

Sarslan Ovr.Start是什麼意思？ –
