Question

我目前正在制作一份大型报告，并且需要一些重要部分的帮助，而这些部分我已经讽刺了几个星期

我有一份报告根据一些事情计算数量但是我想要做的是当“PREQuantity”列为空并且一年中的一周= 1时，从上一年的52周获得数量我知道，案件陈述尚未完成，但基本上我需要报告在前一年的第52周强制执行，以取消优先顺序

SELECT *
FROM #Sales

ORDER BY 3 ASC

DROP TABLE #weeklystores
DROP TABLE #stores
DROP TABLE #storesv2
DROP TABLE #sales
DROP TABLE #Product
END

我按照@Abhay

的建议做了这个改变

 ,case when Sum(PreQuantity)= null and pos.WeekOfYear = 1 then (Select        Sum(PreQuantity) from #presales where WeekOfYear =52 and @year = @Year-1) else       SUM(PreQuantity) end as quantity

它没有用

更改后

Answer 1

我正在尝试根据我的理解完成您的案例陈述：

case when Sum(PreQuantity)= null and WeekOfYear = 1 then 
(Select Sum(Quantity)= null from Sometable a where a.WeekOfYear =52 and a.year = Year-1) 
else null end

注意：假设您有一个列或可以派生一年的列

Sometable可以是多个表连接在一起，您可以从中计算总和（数量）

（年）-1将来自您原来的外部查询，即

FROM pos pos
LEFT JOIN #preweeklystores w ON pos.PosDate = w.[DATETIME]
LEFT JOIN #Product p ON p.ProductCode = pos.ProductCode
    AND p.DivNo = pos.DivNo
    AND pos.DivNo = w.DivNo
WHERE pos.DivNo NOT LIKE '8__' /* Get rid of IRL Regions */
and w.YearWeek >2013

如果你可以使用tablename的别名作为每列的前缀，我将能够给出一个确切的查询。另外，你有一个日期/年份列吗？
