ユニオンと派生テーブルの状況を含むストアド プロシージャがあります。ストアド プロシージャは、基本的に、最初のテーブル (したがって 2 番目) の基準を満たさないCases行を含め、すべての行を返す必要があります。Cases.AssnKey = AssnCtrl.pKey

私はこれに対していくつかのアプローチを試みました。最初に試してみると、基準を満たすすべての行が返されました。その後、顧客がすべてのケースを含めたいと考えていることを知りました。ある時点で、すべての行に加えCaseて、最初のテーブルの基準を満たす行の重複を返すバージョンがありました。2 番目のテーブルでは、重複を防ぐために最初のテーブルからレコードを除外しようとしています。

私は以下に到達しましたが、これは解析されますが、エラーがスローされます

「無効なオブジェクト名 'A'」.

入力パラメーターまたは宣言を含めませんでしたが、すべて正常に機能しています。どんな助けでも大歓迎です！

最後に、(select pKey from A)UNIONの最初の部分のサブクエリからAを使用しようとしています。そこからはアクセスできません。これを行う方法は、AをCTEとして定義し、それに2回アクセスすることです。

ただし、Aは2回評価され、非常にまれな状況では、A's実際には2つがわずかに異なる可能性があることに注意してください。
