Sql 如何在查询中使用会计日历,sql,sql-server,Sql,Sql Server,我有两张桌子，一张是日历，一张是销售。这两个表没有链接在一起。我希望能够编写一个查询，根据会计日历计算一周内的总销售额。这可能吗？我们的会计日历从12月1日开始，每个月底都是星期五任何帮助都将不胜感激财政日历 Period Period1_StartDate Period1_EndDate Period2_StartDate Period2_EndDate........... 2018 01/12/2017 29/12/2017 30

我有两张桌子，一张是日历，一张是销售。这两个表没有链接在一起。我希望能够编写一个查询，根据会计日历计算一周内的总销售额。这可能吗？我们的会计日历从12月1日开始，每个月底都是星期五

任何帮助都将不胜感激

财政日历

Period   Period1_StartDate   Period1_EndDate   Period2_StartDate   Period2_EndDate...........
2018        01/12/2017          29/12/2017     30/01/2018          26/01/2018 


Sales
Sales_order_no   Amount   Date        Customer
111              20453    03/12/2017  abc
112              23154    04/12/2017  bbb
113              20201    10/12/2017  ddd
114              39012    11/12/2017  ccc
115              11111    18/12/2017  eee
116              22222    25/12/2017  uuu

因此，在第1阶段开始日期和结束日期之间有4周的时间。第一周的前两次销售下降。所以第一周的总销售额将是43607

输出

WEEK      Total_Sales
W1        43607
W2        59213
W3        11111
W4        22222

CROSS的两个用途是将会计日历表正常化为一些有用的内容，然后是一个简单的分组

WHERE子句从会计日历中选择一行，从派生视图中选择期间或周或其他任何内容

如果那一周没有销售，就用左边的连接

ON子句查看会计日历和week派生视图，以防派生视图描述的周实际上不在该年中

UNPIVOT是一个非常有用的TSQL操作符，用于规范化数据。基本上，它获取一行并生成新行——在列列表中指定的每列对应一行

在下面的例子中，我在PeriodX_StartDate列上取消Pivot。我最初做了两个unpivot，另一个在PeriodX_EndDate。结束日期是不必要的，但如果您想知道我是如何加入两个unpivot的：我使用交叉应用程序为每周生成一个键，并使用谓词测试它们是否相等。如果没有谓词，则得到笛卡尔积

为了生成周数，我使用了一个交叉应用程序，与@MatBailie的答案中的交叉应用程序非常相似，只是我通过为每个周生成一组参数来避免联合，这些参数被传递到生成日期的函数中

WITH normalizedCal AS (
    SELECT [Period], MonthStart, WeekKey, StartDate, CutoffDate
    FROM fiscal_calendar cal
    UNPIVOT (
        MonthStart FOR StartKey IN (Period1_StartDate, Period2_StartDate, ..., PeriodN_StartDate)
    ) AS startInfo
    CROSS APPLY (
        SELECT 'WK' + CAST((StartIndex / 7) + 1 AS char(1)) [WeekKey]
            , DATEADD(day, startIndex, MonthStart) [StartDate]
            , DATEADD(day, EndIndex, MonthStart) [CutoffDate]
        FROM ( 
            VALUES ( 0, 7 ), ( 7, 14 ), ( 14, 21 ), ( 21, 28 )
        ) rangeValues ( StartIndex, EndIndex )
    ) weekInfo 
)
SELECT [Period], MonthStart, WeekKey, COALESCE(SUM(AMOUNT), 0) [Total_Sales]
FROM normalizedCal nc
LEFT JOIN sales ON sales.Date >= nc.StartDate AND sales.Date < nc.CutoffDate
GROUP BY [Period], MonthStart, WeekKey

根据您提供的示例，您可以执行以下操作：

SELECT *
FROM (
SELECT
    [YEAR]  = YEAR([Date]),
    [MONTH] = MONTH([Date]),
    [WEEK] = DATEPART(week, [Date]) - DATEPART(week, DATEADD(MONTH, DATEDIFF(MONTH, 0, [Date]), 0)),
    SUM(Amount) OVER(PARTITION BY  YEAR([Date]), DATEPART(week, [Date]) - DATEPART(week, DATEADD(MONTH, DATEDIFF(MONTH, 0, [Date]), 0))+ 1) AS TotalSales
FROM Sales
)D 
GROUP BY 
    [YEAR], 
    [MONTH], 
    [WEEK], 
    TotalSales

这将为您提供与您在示例中提供的结果相同的结果，但是，由于我们不知道您的财政日历是如何配置的，您需要查看是否必须将其与之链接

有多少周期起始日期列？13? 截止到第13天开始日期，第13天结束日期？如果可能的话，我会将财政日历反规范化为：年，周期号，开始日期，结束日期。这将使查询更容易@马特贝利是的，13@mikeS-事实上，我的大部分答案只是将最大中心归一化，这样剩下的部分就容易了。有多少周期起始日期列？13? 截止到第13天开始日期，第13天结束日期？如果可能的话，我会将财政日历反规范化为：年，周期号，开始日期，结束日期。这将使查询更容易@马特贝利是的，13@mikeS-事实上，我的大部分答案只是将最大中心归一化，这样剩下的部分就容易了。
