Sql server 用于隔离数据的SQL查询

我的数据集如下：

T

表示运输移动，

F

表示运输静止

我希望数据分类如下，以便进一步分析。需要基于列

Moving

导出

类

，并且应从

0

开始计数，当移动值从

T

变为

F

时，再从

F

从

0

重新计数。下一列

ID

是将移动设置值从

0

分组到增量级别

输出：

---

您可以使用通用表表达式来实现您的目标：

首先，您必须按移动日期对数据进行排序，您可以使用ROW_NUMBER：

下面是一个示例请求：

;WITH orderedMovements AS
(
    SELECT [Date], [Moving], ROW_NUMBER() OVER (PARTITION BY 1 ORDER BY [Date] ASC) AS [RowNum]
    FROM [dbo].[movements]
), completedMovements AS
(
    SELECT omo.[Date], omo.[Moving], 0 AS [Class], 0 AS [Id], omo.[RowNum] AS [RowNumBis]
    FROM orderedMovements omo
    WHERE [RowNum] = 1
    UNION ALL
    SELECT omo.[Date], omo.[Moving], IIF(cmo.[Moving] = omo.[Moving], cmo.[Class] + 1, 0) AS [Class], IIF(cmo.[Moving] = omo.[Moving], cmo.[Id], cmo.[Id] + 1) AS [Id], omo.[RowNum]
    FROM orderedMovements omo
            JOIN completedMovements cmo ON omo.[RowNum] = cmo.[RowNumBis] + 1
)
SELECT [Date], [Moving], [Class], [Id]
FROM completedMovements
OPTION (MAXRECURSION 100);

您是在使用SQL的DB中还是在使用计算列的Spotfire中尝试执行此操作？根据您的回答，我会调整您的标记，因为它们令人困惑。您是在SQL数据库中还是在Spotfire计算列中尝试这样做？根据你的回答，我会调整你的标签，因为它们令人困惑。
