SQL如何按会计季度和年份按日期字段分组 [英] SQL how group by fiscal quarter and year with a date field

问题描述

我正在运行SQL 2008，我的任务是创建一个将供应商名称"和某些信息分组在一起的报告，然后按会计年度和季度对其进行分组.

I am running SQL 2008, I have been tasked to create a report that groups 'vendor name' and certain information together, furthermore group it by fiscal year and their quarters.

按年份分组的进展很好，除了我们的财政开始日期不是1月而是11月.我有一个名为预计到达日期"的日期字段，其格式为"yyyy-mm-dd hh:mm; ss.mmm"，我不确定如何将其分组以进行关联:

It went well up the the grouping by year, except that our fiscal start isnt on January but instead November. I have a date field called 'Expected Arrival Date' that is formatted as 'yyyy-mm-dd hh:mm;ss.mmm' I am not sure how i can group it to associate:

A.会计年度，从11月开始，到10月结束的其余财政年度(例如2012会计年度= 2011年11月开始-2012年10月结束)

A. the fiscal year starting with November year before to the rest of the fiscal year ending at October (example fiscal year 2012 = beginning November 2011 - End October 2012

B..财政季度11月1日至1月31日，2月1日至4月30日，5月1日至7月31日，8月1日至10月31日

B. The fiscal quarter Nov1- Jan31 , Feb1 - Apr30, May1-July31, Aug1-Oct31

这是我已经拥有的代码

SELECT 
    YEAR([Expected Arrival Date])as 'Year',
    MONTH([Expected Arrival Date]) as 'Month',
    [Vendor Name], 
    (SUM(CASE WHEN ([Days Past Due] = 0) THEN [Qty Received] ELSE 0 END) / SUM([Qty Received])) * 100  AS 'On-Time %',
    (SUM(CASE WHEN ([Days Past Due] < 0) THEN [Qty Received] ELSE 0 END) / SUM([Qty Received])) * 100  AS 'Early %',
    (SUM(CASE WHEN ([Days Past Due] > 0) THEN [Qty Received] ELSE 0 END) / SUM([Qty Received])) * 100  AS 'Late %',
    SUM([Qty Received]) aS 'TOTAL'

FROM data_view 
GROUP BY YEAR([Expected Arrival Date]),MONTH([Expected Arrival Date]),[Vendor Name]
ORDER by YEAR([Expected Arrival Date]),MONTH([Expected Arrival Date])

如果您有任何有用的指针来创建一个不错的查询，也将不胜感激.

If you have any helpful pointers to create a nice query it would also be appreciated.

编辑** data_view的结构如下

Edit** The structure of the data_view is as follows

    SELECT        [Receipt #], [Vendor Code], [Vendor Name], [PO Applied], [PO Line #], [Item Code], [Item Description], [Expected Arrival Date], [Receiving Date], [Receiving Date Filter], 
                         [Qty Received], [Qty Ordered], [% Received], [PO Date], [Receipt User], DATEDIFF(dd, CAST(CAST([Expected Arrival Date] AS CHAR) AS DATETIME), 
                         CAST(CAST([Receiving Date] AS CHAR) AS DATETIME)) AS [Days Past Due]
FROM            (SELECT        T1.RCPNUMBER AS [Receipt #], T1.VDCODE AS [Vendor Code], T1.VDNAME AS [Vendor Name], T4.PONUMBER AS [PO Applied], 
                                                    T3.DETAILNUM AS [PO Line #], T2.ITEMNO AS [Item Code], T2.ITEMDESC AS [Item Description], 
                                                    CASE WHEN T3.EXPARRIVAL = 0 THEN CASE WHEN T4.EXPARRIVAL = 0 THEN CAST(CAST(T4.DATE AS CHAR) AS DATETIME) 
                                                    ELSE CAST(CAST(T4.EXPARRIVAL AS CHAR) AS DATETIME) END ELSE CAST(CAST(T3.EXPARRIVAL AS CHAR) AS DATETIME) 
                                                    END AS [Expected Arrival Date], CAST(CAST(T1.DATE AS CHAR) AS DATETIME) AS [Receiving Date], CAST(CAST(T1.DATE AS CHAR) AS DATETIME) 
                                                    AS [Receiving Date Filter], T2.RQRECEIVED AS [Qty Received], T3.OQORDERED AS [Qty Ordered], 
                                                    ROUND(CASE WHEN T2.OQORDERED <> 0 THEN (T2.RQRECEIVED / T2.OQORDERED) * 100 ELSE 100 END, 2) AS [% Received], 
                                                    CAST(CAST(T4.DATE AS CHAR) AS DATETIME) AS [PO Date], T5.ENTEREDBY AS [Receipt User]

推荐答案

类似的方法应该起作用:

Something like this should work:

SELECT 
    YEAR([Expected Arrival Date]) + CASE
        WHEN MONTH([Expected Arrival Date]) IN (11, 12) THEN 1
        ELSE 0
    END As FiscalYear,
    CASE
        WHEN MONTH([Expected Arrival Date]) IN (11, 12, 1) THEN 1
        WHEN MONTH([Expected Arrival Date]) IN (2, 3, 4) THEN 2
        WHEN MONTH([Expected Arrival Date]) IN (5, 6, 7) THEN 3
        ELSE 4
    END As FiscalQuarter,
    ...
GROUP BY
    YEAR([Expected Arrival Date]) + CASE
        WHEN MONTH([Expected Arrival Date]) IN (11, 12) THEN 1
        ELSE 0
    END,
    CASE
        WHEN MONTH([Expected Arrival Date]) IN (11, 12, 1) THEN 1
        WHEN MONTH([Expected Arrival Date]) IN (2, 3, 4) THEN 2
        WHEN MONTH([Expected Arrival Date]) IN (5, 6, 7) THEN 3
        ELSE 4
    END,
    [Vendor Name]
ORDER BY
    FiscalYear,
    FiscalQuarter
;
