  import java.sql.*;
public class TestJDBC {
 public static void main(String[] arges) throws SQLException,ClassNotFoundException{
  String user="root";
  String pwd="mysql";
  //設定URL
  String myjdbc="jdbc:mysql://localhost:3306/test";
  //加載MYSQL驅動
  Class.forName("com.mysql.jdbc.Driver");
  //創建連接會話
  Connection myConnection=DriverManager.getConnection(myjdbc,user,pwd);
  //創建語句塊對象
  Statement Myoperation=myConnection.createStatement();
  //獲取結果集對象
  ResultSet record=Myoperation.executeQuery("select *from test");
  while(record.next()){
   //輸出結果集對象
   System.out.println(record.getInt("id")+","+record.getString("name"));
  }
  //關閉結果集
  try{
   if(record!=null)
    //關閉結果集時需要處理異常
    record.close();
  }catch(Exception e){
   e.printStackTrace();
  }finally{
   try{
    if(myConnection!=null)
     myConnection.close();
   }catch(Exception e){
