Question

我尝试使用当前周的数据（总是在变化）创建一个sql表以及上一年的那些日期数据。我有多个表，我必须加入，但不知道如何将它们全部创建到一个表中。以下是我到目前为止的情况：

-------当前年份-------

DECLARE 
@CURRENTDATE DATE,
@BEGINDATE DATE

SET @CURRENTDATE = CONVERT(DATE,GETDATE()) ---// TODAY'S DATE //---
SET @BEGINDATE = DATEADD(DAY, -7, GETDATE()) ---// A WEEK BEFORE TODAY'S DATE //---

SELECT SALES.*, RECRUITS.Recruits
FROM
(
    SELECT 
    CONVERT(VARCHAR(10), A.[ORDER DATE], 101) AS 'DAY'
    , 'Sales Revenue Current Year' = FORMAT(SUM(A.[GRAND TOTAL]) ,'C', 'EN-US')
    , 'Comm. Sales Volume Current Year' = FORMAT(sum(a. [QUALIFYING VOLUME]), 'C', 'EN-US')
    FROM TABLE1 a
    WHERE CONVERT(VARCHAR(10), A.[ORDER DATE], 101) >= @BEGINDATE AND CONVERT(VARCHAR(10), A.[ORDER DATE], 101) < @CURRENTDATE
    GROUP BY CONVERT(VARCHAR(10), A.[ORDER DATE], 101) 
) SALES,
(
    SELECT 
    CONVERT(VARCHAR(10),a.[start date],101) AS 'DAY'
    ,count(b.[id number]) as Recruits
    from TABLE2 a
    left join
    TABLE3 b
    on a.enroller = b. [id number]
    WHERE CONVERT(VARCHAR(10), A.[START DATE], 101) >= @BEGINDATE AND CONVERT(VARCHAR(10), A.[START DATE], 101) < @CURRENTDATE
    group by a.[start date] 
) RECRUITS
WHERE SALES.DAY = RECRUITS.DAY

我上一年的脚本相同。除了我将日期设置为-366和-373天之外，它是相同的。任何帮助都会很棒！

您可以使用带有“OR”的多个日期，如下所示，但更好的解决方案是使用日期维度表，每个日期日期的列表，例如“WeekOfYear”，“WeekOfMonth”，“QuarterOfYear” ，“IsHoliday”等。然后你可以加入你对象的日期并查询“t1.WeekOfYear = t2.WeekOfYear”。

DECLARE 
    @EndDate DATE           = GETDATE()  ---// TODAY'S DATE //---
    , @StartDate DATE       = DATEADD(DAY, -7, GETDATE()) ---// A WEEK BEFORE TODAY'S DATE //---
    , @LYStartDate DATE     = DATEADD(YEAR, -1, GETDATE()) ---// A YEAR BEFORE TODAY'S DATE //---
    , @LYEndDate DATE       = DATEADD(DAY, -7, DATEADD(YEAR, -1, GETDATE())) ---// A YEAR AND A WEEK BEFORE TODAY'S DATE //---

SELECT SALES.*, RECRUITS.Recruits
FROM
(
    SELECT 
        'DAY' = CONVERT(VARCHAR(10), A.[ORDER DATE], 101)
        , 'Sales Revenue Current Year' = FORMAT(SUM(A.[GRAND TOTAL]) ,'C', 'EN-US')
        , 'Comm. Sales Volume Current Year' = FORMAT(sum(a. [QUALIFYING VOLUME]), 'C', 'EN-US')
    FROM TABLE1 a
    WHERE (
        (CAST(A.[ORDER DATE] AS DATE) >= @StartDate AND CAST(A.[ORDER DATE] AS DATE) <= @EndDate)
        OR
        (CAST(A.[ORDER DATE] AS DATE) >= @LYStartDate AND CAST(A.[ORDER DATE] AS DATE) <= @lyEndDate)
        )
    GROUP BY CAST(A.[ORDER DATE] AS DATE) 
) SALES,
(
    SELECT 
        'DAY' = CAST(a.[start date] AS DATE)
        , Recruits = COUNT(b.[id number])
    FROM TABLE2 a
        LEFT JOIN TABLE3 b
            ON a.enroller = b. [id number]
    WHERE (
        (CAST(A.[START DATE] AS DATE) >= @StartDate AND CAST(A.[ORDER DATE] AS DATE) <= @EndDate)
        OR
        (CAST(A.[START DATE] AS DATE) >= @lyStartDate AND CAST(A.[ORDER DATE] AS DATE) <= @LYEndDate)
    GROUP BY CAST(a.[start date] AS DATE)
) RECRUITS
WHERE SALES.DAY = RECRUITS.DAY

本周的数据表和一年前的那些日期
