SQL Server ビューからのレコードを表示するリストビューがあります。データは customerid によってフィルター処理され、ビューの実行時に 2 つの一意のレコードが含まれます。ただし、リストビューは最初のレコードのみを表示し、それを 2 回表示します。したがって、リストビューには 2 つのレコードが表示されますが、ビューによって生成された 2 つのレコードは表示されず、ビューの最初のレコードが 2 回表示されるだけです。これが明確であることを願っています。
何が起こっている？私は何時間も運が悪かった。

ユニオンクエリに変更しましたが、linq は気に入りません。

エラーが表示されます...クエリ結果を複数回列挙することはできません。
私は何を間違っていますか？ありがとう
