我试图弄清楚如何创建一个由多个列划分的序列，其中序列必须重新设置，而另一个（基于日期的）列是不连续的

问题：医院ADT（入院/出院/转院）事件发生在特定时间点，但我们希望将这些事件转化为具有持续时间（时间跨度）的活动，即我们有开始日期，但没有结束日期，这是基于下一个适当的ADT事件。我们已经在代码中实现了这一点，但也希望在SQL中实现这一点以提高性能。e、 g.查找在ICU待了48小时以上的患者

我们需要记录六个不同级别的现场位置的持续时间：设施、护理点、建筑、地板、房间和床

因此，对于每个事件，我们想知道它们在每个特定的站点位置停留了多长时间。每个流中最后一个活动的结束日期要么为空（仍然是住院患者），要么为患者出院日期

以下是我当前的解决方案：

-- Create a sequence for each site location
INSERT INTO ADT_Activity_Sequence
SELECT 
  [Stream], 
  [Event],
  [Started],
  [Facility], 
  ROW_NUMBER() OVER (PARTITION BY [Stream], 
    ISNULL([Facility], [Event]) 
    ORDER BY [Started]) AS [FacilitySequence], 
  [PointOfCare], 
  ROW_NUMBER() OVER (PARTITION BY [Stream], 
    ISNULL([Facility], [Event]), 
    ISNULL([PointOfCare], [Event]) 
    ORDER BY [Started]) AS [PointOfCareSequence]
  -- and so on for all site locations
FROM ADT_Event
INNER JOIN ADT_Stream ON ADT_Event.Stream = Stream.Id
例如：

然后根据序列创建持续时间：

我已经兜圈子有一段时间了：）谢谢你的帮助，谢谢

如果我正确理解您的问题，您需要连续的
行号（）。您可以使用stream
row_NUMBER（）
和单个序列之间的行号差异来生成一个组，在该组上为设施和护理点订购行号

由于这些不是使用
设施
和
护理点
直接分组的，而是根据顺序进行分组的，因此如果患者再次切换回同一设施或护理点，则会重置顺序

用这样的东西

您可以根据需要根据这些顺序生成日期范围

您能否澄清所提供的表格中哪些是源数据，哪些是预期结果。另外，请添加一个带有SQL Server版本的标记。我没有添加版本标记，因为它是SQL Server>=2005，但现在已将其添加为基线。如果不清楚，很抱歉，但ADT_事件和ADT_流是源表，ADT_活动表正从它们生成。为了简洁起见，我省略了一些其他代码，但主要是处理要更新的事件和流的内务处理。您能否清楚地显示您的样本数据是什么样子的，以及基于该样本数据的最终结果应该是什么。现在问题中有5个表，其中一些有
Stream=3
，一些没有。这令人困惑。关于版本：SQL Server 2012+具有类似于
LEAD
和
LAG
的功能，这可能会大大有助于计算持续时间。没问题，我将创建一个SQLFIDLE模式和一些测试数据。ughai击败了我：）正在处理，谢谢！我唯一需要改变的是在每个站点位置的CTE分区上添加一个ISNULL检查，如果为null，则使用活动PK，因为位置可能并不总是被设置，所以必须在null.FWIW上重置，进一步的测试发现了另一个问题，我可能没有对此进行充分的解释，但每个站点位置都有一个层次结构，因此，我必须将CTE中的每个较低位置划分为较高级别的位置，因为它们可以共享。例如，ICU的同一个密钥可能位于两个不同的设施中，因此您必须按设施和护理点对护理点位置进行划分，以此类推，划分不同的级别。
