Question

我已经在线查看，但找不到可以返回我需要的解决方案，并且希望本网站的专家可以像过去一样帮助我。

我有一个SQL数据库，用于保存与建筑设备相关的带时间戳的维护呼叫。

我可以查询维护信息，例如通话次数，平均工作时间，通话平均开放时间以及按月分组结果（以给出一年中的趋势）。

下一阶段是我提供设备正常运行时间的指示。我有停机时间（为了这个目的，这是打电话的时间），我可以添加一个计数来给出设备的总数。我想根据一年中每个月的小时数，项目数和打电话的总时间来显示设备可供使用的时间百分比（正常运行时间）。

e.g。

月 - 号召唤 - 平均工具时间（小时） - 平均开放时间（小时） - （必需）正常运行时间
Jan - 4 - 0.37 - 1.00 - 92％
2月 - 3 - 0.83 - 35.6 - 87％
3月 - 5 - 0.50 - 1.85 - 85％
4月 - 10 - 0.72 - 119.5 - 72％

等

有人会建议一个可以返回每个月份中我可以在现有查询中使用的日期的查询吗？
此外（对不起，请稍等一下）...如果2月份召集电话而4月份没有关闭，我怎能在3月份将停机时间包括在内？有没有办法考虑到这一点？

我已经在下面提供了完整的查询，我提前为格式化（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。

非常感谢您提供任何帮助或指导。

以下示例查询

您可能想要检查一个月中的小时数是否应仅包含工作日的工作时数，否则，您的百分比可能会有所偏差。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，我省略了大部分查询，并将字段设置为零。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

查询将一年中每个月的日期作为列表返回？
