代表季度中几周的问题

Question

我正在尝试编写一个脚本，该脚本将返回该季度的第一天和一周的最后一天，即 04/01-04/06，该季度每周的第一天和最后一天，例如 06/ 23-06-29 以及该季度的最后一周，例如 06/30 或 12/29-12/31。

      ,[Date]
      , CASE 
            WHEN GETDATE() BETWEEN FirstDateofWeek AND LastDateofWeek 
            THEN FORMAT([Month], '00') + '/' + FORMAT([Day], '00') 
            ELSE '' 
        END AS [Week_Date_Axis]
      , CASE 
            WHEN GETDATE() BETWEEN FirstDateofWeek AND LastDateofWeek 
            THEN [Month] * 100 + [Day] 
            ELSE 0

我们的周从星期日开始，因此我返回 03/31（星期日）作为季度的开始，这是错误的，应该是 04/01（星期一）。我也没有得到滚动月份，例如，05/26-05/01 应该是 05/26-06/01，最后该季度的最后一周显示为 06/30-06/06，而它应该是只是06/30。任何想法或提示都会有帮助，谢谢

从脚本返回

Answer 1

根据一些疯狂的猜测，未经任何测试，我建议：

;WITH strings AS(
SELECT
  Year
  ,Quarter
  ,WeekOfYear
  ,string = FORMAT(MIN(Date), 'MM/dd', 'en-US') + '-' + FORMAT(MAX(Date), 'MM/dd', 'en-US') 
FROM Tbl_Date_dim
GROUP BY
  Year
  ,Quarter
  ,WeekOfYear
)
SELECT
  d.*
  ,s.string
FROM Tbl_Date_dim d
JOIN strings s
  ON d.Year = s.Year
     AND d.Quarter = s.Quarter
     AND d.WeekOfYear = s.WeekOfYear
