wso2 - WSO2 データサービスが名前付きクエリに対して機能しない (prepare ステートメント)

Question

Oracle XE DB の HR スキーマに接続する単純なデータサービスを実行しようとしていました。入力パラメーターを受け取り、渡されたバインドデータに応じて結果を取得する操作を含む単純なクエリを作成しました。

私のクエリは以下のようになります

SELECT first_name,last_name,email,phone_number,hire_date,salary 
FROM employees 
WHERE first_name like :Bind_name

入力変数 Bind_name を追加し、サービスを要求するときにそれを渡します。

しかし、サービスをトリガーすると、以下のエラーが表示され、Web 上で関連するヘルプが見つかりませんでした。
