自定義函式回撥：

1、params：用於描述自定義函式佔位符引數或命名引數型別；SqlParameter用於描述IN型別引數、SqlOutParameter用於描述OUT型別引數、SqlInOutParameter用於描述INOUT型別引數、SqlReturnResultSet用於描述呼叫儲存過程或自定義函式返回的ResultSet型別資料，其中SqlReturnResultSet需要提供結果集處理回撥用於將結果集轉換為相應的形式，hsqldb自定義函式返回值是ResultSet型別。

2、CallableStatementCreator：提供Connection物件用於建立CallableStatement

3、outValues：呼叫call方法將返回型別為Map<String, Object>物件；

4、outValues.get("result")：獲取結果，即通過SqlReturnResultSet物件轉換過的資料；其中SqlOutParameter、SqlInOutParameter、SqlReturnResultSet指定的name用於從call執行後返回的Map中獲取相應的結果，即name是Map的鍵。
