sql-server - select * into コマンドが実行された後でも、ストアド プロシージャは一時テーブルを作成しません。

Question

最近、SQL Server ストアド プロシージャが一時テーブルを作成するように特に要求されたときに作成されないという問題に遭遇しました。ただし、エラーはスローされません。一時テーブルにデータを挿入しようとすると失敗します。この手順で何が間違っているのか教えてください。

以下のコマンドで実行します。エラーが発生します。

Exec AAH_CDC_PROC @SourceSystemName = 'XYZ', @DomainTypeDescription = 'ABC', @HashDescription = 'AAH';
