Connecting JdbcRowSet with a Predefined Connection Object
This section describes how to connect a JdbcRowSet object to a database server with a predefined connection object.
Another way to connect a JdbcRowSet object to a database server is to pass a predefined connection object to the JdbcRowSetImpl constructor. Here is a sample sequence of method calls:
/* OracleRowSetConnectionObject.java * Copyright (c) HerongYang.com. All Rights Reserved. */ import java.sql.*; public class OracleRowSetConnectionObject { public static void main(String [] args) { Connection con = null; try { // Create a Connection object Class.forName("oracle.jdbc.OracleDriver") ; con = DriverManager.getConnection( "jdbc:oracle:thin:Herong/TopSecret@//localhost:1521/XE"); // Pass the Connection object to the new JdbcRowSet object javax.sql.rowset.JdbcRowSet jrs = new com.sun.rowset.JdbcRowSetImpl(con); // Set a SQL statement jrs.setCommand("SELECT 'Hello world!' FROM DUAL"); // Connect and run the statement jrs.execute(); // Get the result jrs.next(); System.out.println("Result: "+jrs.getString(1)); // Close resources jrs.close(); con.close(); } catch (Exception e) { e.printStackTrace(); } } }
If you try to compile the sample program with JDK 17, you will get an error:
herong> javac OracleRowSetConnectionObject.java temp/OracleRowSetConnectionObject.java:17: error: package com.sun.rowset is not visible = new com.sun.rowset.JdbcRowSetImpl(con); ^ (package com.sun.rowset is declared in module java.sql.rowset, which does not export it) 1 error error: compilation failed
If you are still using JDK 1.8, you can continue to use the sample program:
herong> \Progra~1\java\jdk1.8.0_45\bin\javac -cp .;ojdbc6.jar OraclePreparedSelect.java OracleRowSetConnectionObject.java:17: warning: com.sun.rowset.JdbcRowSetImpl is Sun proprietary API and may be removed in a future release = new com.sun.rowset.JdbcRowSetImpl(con); ^ 1 warning herong> \Progra~1\java\jdk1.8.0_45\bin\java \ -cp .;ojdbc6.jar OraclePreparedSelect Result: Hello world!
