    BasicDataSource bds = new BasicDataSource();


    bds.setDriverClassName("com.mysql.jdbc.Driver");


    bds.setUrl("jdbc:mysql://localhost:3306/mydb");


    bds.setUsername("root");


    bds.setPassword("");


    try {


      Connection con = bds.getConnection();


      try {


        Statement st = con.createStatement();


        ResultSet rs = st.executeQuery("SELECT * FROM student");


        ResultSetMetaData md = rs.getMetaData();


        int col = md.getColumnCount();


        System.out.println("Number of Column : " + col);


        System.out.println("Columns Name: ");


        for (int i = 1; i <= col; i++) {


          String col_name = md.getColumnName(i);


          System.out.println(col_name);


        }


        con.close();


      } catch (SQLException s) {


        System.out.println("SQL code does not execute.");
