CTEによる最上位のユニオンエラー
私にとっておそらく最も高度なクエリであるCTEクエリを記述しようとしています。 （3週間SQLを使用して作業中）。このクエリを実行しようとすると、次のエラーが発生します。
メッセージ252、レベル16、状態1、行4再帰的共通テーブル式「Sixer」には、トップレベルのUNION ALL演算子が含まれていません。
だからここに細いです-私はDDL（これは巨大です）を含めており、テーブルファイバーとテーブルは最初は同じに見えますが、最初にファイバーに存在しないacctNumを含むことができ、その逆も同じであるという事実とは異なります。これがDDLです

エラーはこのCTEが原因です：
WITH Sixer As
(
Select
DISTINCT(Doctor) As Doctor
,Practice
,AnnRev
FROM Sixer -- the error occurs here
)
Sixerという名前のテーブルとSixerという名前のcteがあります。したがって、クエリパーサーがFROM Sixer、これはcteを考慮します（テーブルは考慮しません）。そして、これは許可されていません-それが再帰的なCTE（したがってエラー）でない限り。
解決策は簡単です。CTE名を別の名前に変更します。
WITH Six As -- CTE name changed
(
SELECT DISTINCT
Doctor
,Practice
,AnnRev
FROM Sixer
)
---
---
LEFT JOIN Six sx -- and used here
---
別の解決策は、スキーマ名（dbo.Sixer）。この方法で、CTEに同じ名前を付けることができます。
WITH Sixer AS
(
SELECT DISTINCT
Doctor
,Practice
,AnnRev
FROM dbo.Sixer -- table name prefixed with schema
)
--- -- no other change
エラーとは関係なく、Doctorの前後の括弧を削除しました。 DISTINCTは関数ではありません。 SELECTリスト全体に適用されます。
