これらの3つのWITHASセクションをUNIONしようとすると助けが必要です。次のエラーが発生します。 Error Message when trying to UNION Multiple WITH AS！

2つの問題があります。まず、CTE間にコンマが必要です。次に、UNIONedステートメントのグループに対して1つのORDERBYしか持つことができません。最後に1つのORDERBYを使用するだけです。

ネストされたCTEについて一言で言えば、参照されるたびに評価されます。別の言い方をすれば、それらは一時テーブルのように動作せず、データは特別な方法でキャッシュされません。したがって、CTEが複数回参照されている場合（つまり、UNIONで1回、RunningTotalサブクエリで1回）、パフォーマンスが低下する可能性があります。これを示すために、クエリと数百行のみを使用して単純なリグを設定しました。最初の呼び出し（43,070回の読み取り）はクエリです。次の4回は、一時テーブルを使用してCTEの結果をキャッシュし、合計702回の読み取りのみを登録する私の書き直しです。

この書き換えをデータで試して、読み取りを比較し、違いが見られた場合はお知らせください。

'In'についての別の言葉-それはあなたが思っているように振る舞わない。したがって、クエリ内のすべての「In」参照を「=」に変換しました。これがうまくいかない場合は、変数@ Projectlisting、@ ToPeriod、@ RecordTypesのサンプル値を投稿してください。それまでの間、このトピックに関するErlandSommarskogの優れた記事を確認することをお勧めします。
