次の条件の顧客トレンドの追加列であるクエリを作成しようとしています

Case When *SalesQty2012* is higher than *SalesQty2011* THEN "Increasing"
Case When *SalesQty2011* is higher than *SalesQty2012* THEN "Decreasing"
Case When *SalesQty2011* is equal 0 (No Sales) AND  *SalesQty2012* grater than 0 THEN "NEW"
Case When *SalesQty2012* is equal 0 (No Sales) AND  *SalesQty2011* grater than 0 THEN "Lost"

これは、最後の2つの条件が正しく適用されていない場所で書いたものです

    Select top 10 [Status],DivisionCode,CustomerCode,CustomerName,
SalesQty2012=ISNULL(SalesQty2012,0),

新規および紛失のシナリオを処理するためのクエリの書き方を教えてください。

どうもありがとうアリ

上記のクエリで問題が発生しました。2012 年の売上がまだ終わっておらず、比較が間違っているという理由だけで、salesQty2012 の期間が SalesQty2011 と同じであることを確認する必要があります。私の質問は、現在の期間に従って salesqty 2011 をもたらすクエリをどのように作成できるかです。上記のデータを取得するための私の元のクエリ:
