查询是否将周末（星期六和星期日）滚动到下一个工作日（星期一），如果是同一月份，

Question

因此，如果我们从一个周末开始一个月，则第一天将成为周末，并且应该延期至工作日，同样，假期也应退回到前一天。

表中的数据看起来像这样

我尝试了以下查询

SELECT 
     d.Date
    ,d.DateKey
    ,d.IsBusinessDay
    ,d.MonthKey
    ,ISNULL(MAX(d2.DateKey),d.DateKey) AS RecognizedBusinessDateKey
    ,DENSE_RANK() OVER(PARTITION BY d.MonthKey ORDER BY ISNULL(MAX(d2.DateKey),d.DateKey)) AS RecognizedBusinessDateNumber
FROM dbo.DimDate d
    LEFT JOIN dbo.DimDate d2 
        ON d2.MonthKey <= d.DateKey
WHERE d2.IsBusinessDay = 'Business Day'
  AND d2.DateKey > 0
  AND d2.Date BETWEEN '8/1/2020' AND '8/31/2020'
GROUP BY 
     d.Date
    ,d.DateKey
    ,d.IsBusinessDay
    ,d.MonthKey
