从另一行中的日期时间值中排除时间

Question

我正在尝试获取有关处理工单所花费时间的报告。基本上，我有多名员工在处理一张工单，并且想报告他们在工单上工作了多少时间。

例如：

员工 A 从中午 12 点到下午 5 点处理了一张工单，在此期间，工单处于“待处理”状态一个小时，即从下午 3 点到下午 4 点......这需要从员工花费的总时间中排除票上的A。

计算：

时差：5

待处理状态小时：1

以小时为单位的最后时间：4

我需要您的帮助，了解如何通过 SQL 完成此操作。

这是我目前所拥有的：

DROP TABLE IF EXISTS #INC_Data;
    CREATE TABLE #INC_Data (
        IncidentNumber NVARCHAR(20) NOT NULL
        ,Mi_Definition VARCHAR(255) NOT NULL
        ,Mi_Value VARCHAR(255)
        ,Mi_Start DATETIME
        ,Mi_End DATETIME
        )

INSERT INTO #INC_Data (
    IncidentNumber
    ,Mi_Definition
    ,Mi_Value
    ,Mi_Start
    ,Mi_End
    )

编辑：在对预期结果做出更多说明后更新了以下 SQL。

Select  Incident.IncidentNumber, Assignment.Mi_Value Assignee, 
    Assignment.Assignment_Start Assign_Start, Assignment.Assignment_End Assign_End,
    Pending.Pending_Start, Pending.Pending_End,

From 子句是一个派生表，它将返回一个不同的事件编号结果集。从那里，您可以使用外部应用列出每个人以及分配给他们的工单的时间范围。下一个外部应用获取待处理状态的时间范围，并将其应用于分配给该工单的每个人。一旦有了这两个日期范围，只需找出任何重叠的持续时间。案例陈述分解了每个可能的重叠场景......

（下面的列是以分钟为单位的持续时间）

EndingOverlap 是指挂起状态在分配期间开始并超过分配结束时

StartingOverlap 是指挂起状态在分配之前开始但在分配开始之后结束。

PendingWithinAssignment 将涵盖工单在分配给一个人时进入和退出待处理状态的情况。

AssignmentWithinPending 涵盖工单在整个分配期间（如果不是更长）处于待处理状态的情况。

这样，您可以将 Assignment_Duration 列减去上述 4 列。
