Question

我创建了一些代码，允许我在特定的子视觉后显示我的数据中的每条记录

SELECT
ID,
Received,
Closed,
Subsymptom,
DATEDIFF(HOUR, received, COALESCE(closed, GETDATE())) AS 'HoursOpen'
FROM
   vw_UserView_OpenAndClosed A
WHERE closed > 
(SELECT  MAX(closed)
FROM    
    vw_UserView_OpenAndClosed SUB
WHERE   
    Subsymptom = 'INSTALL'
    AND received >= '2017-06-01'
    AND SUB.name = A.name)

数据看起来像这样

ID      received    closed      Subsymptom            HoursOpen
1306438 2017-06-20  2017-06-21  ISSUES                19
1305393 2017-06-18  2017-06-19  REQUEST               12    
1299203 2017-06-05  2017-06-05  REQUEST               0
1299415 2017-06-05  2017-06-06  SPECIFIC FAILURE      2

我希望能够做的是创建一个新列，告诉我自原始子症状命名为＆＃39; INSTALL＆＃39;以来已经过了多少时间。被提出来了。

ID可能有差距，我会有多个名称＆＃39;

我已经尝试过选择Max（已关闭）加入，但我无法让它工作，我认为我在完全错误的轨道上并且有一些头脑模糊。

自安装关闭以来收到的天数 - 计算从安装关闭日期到RECEIVED日期的天数。

（稍后将绘制图表，表明在第0天，第1天，第2天等收到INSTALL新记录之后）

编辑：感谢您澄清您的意见并添加所请求的样本数据。一旦我拥有它，这是轻而易举的事。因此，将来发帖时请务必添加，以确保最快的响应！

以下是代码：

DECLARE @Table TABLE (ID bigint, Received DATETIME, Closed DATETIME, Subsymptom varchar(50), [Name] varchar(50))
DECLARE @Now DateTime = GETDATE()

INSERT INTO @Table
VALUES
(1306438 , '2017-06-20', '2017-06-21', 'ISSUES', 'BROOM'),
(1299203 , '2017-06-05', '2017-06-05', 'REQUEST', 'BROOM'),
(1305393 , '2017-06-18', '2017-06-19', 'REQUEST', 'CHIVE'),
(1299415 , '2017-06-06', '2017-06-06', 'SPECIFIC FAILURE', 'BROOM'),
(1299222 , '2017-06-05', '2017-06-05', 'ISSUES', 'BROOM'),
(1299112, '2017-06-05', '2017-06-05', 'CONTACTLESS', 'BROOM'),
(1279168 , '2017-06-01', '2017-06-03', 'INSTALL', 'BROOM'),
(1287965 , '2017-06-10', '2017-06-10', 'INSTALL', 'CHIVE')

SELECT  T.ID, 
        T.Received, 
        T.Closed, 
        T.Subsymptom,
        T.[Name],
        DATEDIFF(HH, T.Received, COALESCE(T.Closed, @Now)) AS 'HoursOpen',
        DATEDIFF(DD, T2.Closed, T.Received) AS [Days Received since Install Closed]
FROM @Table T
JOIN @Table T2
    ON T.[Name] = T2.[Name]
    AND T2.Subsymptom = 'INSTALL'
WHERE T.Closed > T2.Closed

结果如下：

您要保证的是每个名字只有一个“安装”子症状的实例。如果是这种情况，此查询将始终有效。我的结果与您的结果不同的原因是因为您只提供了日期（而不是DateTimes），因此计算结果略有偏差。但是，基本上，你只是将每个记录加入其原始安装 - 抓住原始记录的关闭时间 - 并将其与当前记录的接收时间进行比较。非常简单 - 而且直截了当。

如果这不是您想要的，请告诉我。
