从另一行的日期时间值中排除时间

Question

我正在尝试获取有关在机票上花费的时间的报告。基本上，我有多位员工在处理一张票证，并且想报告他们在票证上工作了多少时间。

例如：

员工A从12 PM到5 PM工作了一张票，在此票上“挂起”了一个小时，即从3 PM-4 PM ..这需要从员工A花费的总时间中排除在票上。

计算：

时差：5

待处理状态的票价：1

以小时为单位的最终时间：4

我需要您的帮助来完成SQL。

这是我到目前为止的内容：

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

        ,Mi_Start DATETIME
        ,Mi_End DATETIME
        )

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

查询以计算受让人在机票上花费的时间，并排除其中的待处理时间

;WITH CTE

我不确定您要如何显示结果，但以下查询应为您提供前进的路径。

SELECT Incident.IncidentNumber, DurationInMinutes.Total DurationInMinutes, PendingInMinutes.Total PendingInMinutes
FROM    (
        Select  Distinct IncidentNumber 
        From    #INC_Data
    ) Incident
Outer Apply (
        Select  SUM(DATEDIFF(minute, Mi_Start, Mi_End)) Total
        From    #INC_Data sub
        Where   sub.Mi_Definition = 'Assigned to Duration'
        And sub.IncidentNumber = Incident.IncidentNumber
        ) DurationInMinutes
Outer Apply (
        Select  SUM(DATEDIFF(minute, Mi_Start, Mi_End)) Total
        From    #INC_Data sub
        Where   sub.Mi_Definition = 'Incident State Duration'
        And sub.Mi_Value = 'Pending'
        And sub.IncidentNumber = Incident.IncidentNumber
        ) PendingInMinutes
Order by IncidentNumber

From子句是派生表，将返回不同的事件编号结果集。从那里，您可以使用外部应用程序求和分配给某人的时间（DurationInMinutes），第二个外部应用程序将执行相同的操作，但要查看在待处理状态下花费的时间。我以分钟为单位返回了总计，但是如果您想要的是详细程度，那么修改它就很简单，只需返回小时即可。
