そして、これをSQL plusに入力すると、次のエラーが発生します。
無効な関係演算子
私がやろうとしていること：REFCURSORを使用してasp.netアプリケーションにsecordsetを返すこのストアドプロシージャがあります。2つの入力パラメーターを指定します。1は日付（IN_DATE）で、1は演算子（IN_DATE_OPERATOR）です。プログラムは「||IN_DATE_OPERATOR||」の場合に機能します は、=または>=のいずれかに置き換えられます。この問題は、where句で使用する演算子を">="または"="にする.Netアプリケーションで何が発生するかに基づいており、実行時までどちらかわかりません。
私はこれが間違っていることを知っていますが、IN_DATE_OPERATORが関係演算子であることをOracleに再認識させる方法がわかりません。動的演算子を使用する他のメソッドを使用できます（CASE WHEN IN_DATE_OPERATOR ='=' THEN'=' ELSE'> ='ENDも使用できません）が、個別のストアドプロシージャ全体を作成したくありません。これに加えて、または完全に動的なwhere句を維持する必要があります。私の理想的な解決策は、このクエリへの変更をできるだけ少なくすることです。助言がありますか？
編集：わかりました。クエリを編集しました。次のようになります。
