【问题描述】：

我在网上查看过，但找不到可以返回我需要的解决方案，并希望该网站上的专家可以像您过去一样为我提供帮助。

我有一个 SQL 数据库，其中包含与建筑设备相关的带有时间戳的维护电话。

我可以查询维护信息，例如呼叫次数、平均工作时间、呼叫已打开的平均时间，并且我已按月对结果进行分组（以给出一年中的趋势）。

下一个阶段是我提供设备正常运行时间的指示。我有停机时间（为此，这是呼叫打开的时间），我可以添加一个计数来给出设备的总数。我想显示设备可用的时间百分比（正常运行时间），基于一年中每个月的小时数、项目数和通话打开的总时间。

例如

月 - 拨打电话次数 - 平均工具时间（小时） - 平均打开时间（小时） - （必需）正常运行时间

一月 - 4 - 0.37 - 1.00 - 92%

二月 - 3 - 0.83 - 35.6 - 87%

三月 - 5 - 0.50 - 1.85 - 85%

四月 - 10 - 0.72 - 119.5 - 72%

等

有人可以建议一个查询，该查询将返回我可以在现有查询中使用的每个月份的天数吗？

此外（抱歉，这里有点推）...如果在 2 月提出了一个电话，但直到 4 月才结束，我怎么能包括 3 月的停机时间？有没有办法考虑到这一点？

我在下面包含了完整的查询，我提前为格式（和质量）道歉。我应该补充一点，这是一个托管数据库，所以除了返回值之外，我不能添加表或做很多事情。

非常感谢您提供的任何帮助或指导。

非常感谢 加里

【问题讨论】：

您的间隔表是什么样的？

@lrb - 我不确定这个术语，抱歉

FROM Intervals A

@lrb, 'A' 指的是月份数，我不认为它是一个单独的表，我认为它是 SQL 的内置函数。

您的Interval A 表中是否包含Day 信息？它是像表一样的日历吗？

【参考方案1】：

您可能想检查一个月中的小时数是否应仅包含工作日的工作时间，否则，您的百分比可能会出现偏差。这适用于 sql server 2012 和 DATEFROMPARTS。您可能需要为此提出自己的功能。为简洁起见，我省略了您的大部分查询，并将您的字段设置为零。但基本概念是相似的。

SELECT
    Detail.Month,
    Detail.Number,
    SumNoCallsMade=SUM(NoCallsRaised),
    AvgAvgToolTime=AVG(AvgToolTimeHrs),
    AvgAvgTimeOpen=AVG(AvgTimeOpenHrs),
    HoursInMonth=MAX(HoursInMonth),
    AverageUpTime=AVG(AvgToolTimeHrs) / CAST(MAX(Detail.HoursInMonth) AS DECIMAL(18,2)),
    AverageOpenTime=AVG(AvgTimeOpenHrs) / CAST(MAX(Detail.HoursInMonth) AS DECIMAL(18,2))
FROM
(
    SELECT 
        A.Month,
        A.Number,
        NoCallsRaised=0,
        AvgToolTimeHrs=0,
        AvgTimeOpenHrs=0,
        HoursInMonth=(24 * DATEPART(DAY, DATEADD(DAY, -1, DATEADD(MONTH, 1, DATEFROMPARTS( DATEPART(YEAR,GETDATE()),A.Number,1)))))

    FROM 
        Intervals A
    WHERE 
        A.Type = 'Month' 
)AS Detail
GROUP BY
    Detail.Month,
    Detail.Number
ORDER BY 
    Detail.Number
