私は現在、巨大なレポートに取り組んでおり、皮肉なことに何週間も取り組んできた重要な部分について助けが必要です

いくつかのことに基づいて数量を計算するレポートがありますが、「PREQuantity」列が null で、年の週 = 1 の場合、前年の 52 年の週から数量を取得します。ケース ステートメントは未完成です。わかっていますが、本質的には、前年度の第 52 週にプレクォンティについて強制するレポートが必要です。

@Abhayの提案に従って、この変更を加えました

 ,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

うまくいきませんでした

私が理解していることに基づいて、あなたのケースステートメントを完成させようとしています:

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：列があるか、年の列を導出できると仮定します

sometable は、sum(quantity) を計算できる場所から結合された多くのテーブルにすることができます

(年)-1 は、元の外部クエリから取得されます。

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

テーブル名のエイリアスを各列のプレフィックスとして使用できれば、正確なクエリを実行できます。また、日付/年の列はありますか?
