我需要计算每件商品的当日销售额、MTD销售额和YTD销售额

Question

我需要找到MTD (月初至今)和年初至今的销售价值为每个项目。而且，我对需要查找销售报告的整个数据进行了筛选。根据这个日期，它应该会找到MTD和YTD的销售额。它应该按条形码对项目进行分组。例如:在我的筛选器中，如果我输入:8月21日，我应该找到当天的销售和MTD，YTD。

它可以很好地处理当前日期，但如果我使用除当前日期之外的任何日期，则MTD和YTD会有所不同

SELECT Barcode,
       SUM(CASE WHEN DATE = DATEADD(DAY, DATEDIFF(DAY, 0, GETDATE()), -1) THEN sales_amount ELSE 0 END) AS day_1,
       SUM(CASE
                WHEN MONTH(date) = (MONTH(GETDATE() - 1))
                 AND YEAR(date) = YEAR(GETDATE() - 1) THENsales_amount
                ELSE 0
           END) AS month_t,
       SUM(CASE
                WHEN MONTH(date) = (MONTH(GETDATE() - 1))
                 AND YEAR(date) = YEAR(GETDATE() - 1) - 1 THEN GL_TOTALTTC
                ELSE 0
           END) AS lastyear_tm,
FROM sale
WHERE type = 'FFO'
  AND store = 'AE001A'
  AND (DATE = DATEADD(DAY, DATEDIFF(DAY, 0, GETDATE()), -1)
    OR ((MONTH(date) = (MONTH(GETDATE() - 1))
     AND YEAR(date) = YEAR(GETDATE() - 1))
     OR (MONTH(date) = (MONTH(GETDATE() - 1))
     AND YEAR(date) = YEAR(GETDATE() - 1) - 1)))
GROUP BY barcode;

您可以使用条件聚合：

select bar_code,
       sum(case when date >= dateadd(day, -1, convert(date, getdate()) then sales_amount end) as yesterday,
       sum(case when month(date) = month(getdate()) and year(date) = year(getdate()) then sales_amount end) as mtd,
       sum(case when year(date) = year(getdate()) then sales_amount end) as ytd
from sale
where type = 'FFO' and store = 'AE001A' 
group by barcode;
