例程

 

    //初始化DataSource，只需要一个appname，我们会帮您配好
    TDataSource ds = new TDataSource();
    ds.setAppName("app_name");
    ds.init();

//其余的just jdbc
Connection con = null;
con = us.getConnection();

PreparedStatement ps = con.prepareStatement("select * from auction_auctions limit 10");

ResultSet rs = ps.executeQuery();

while (rs.next()) {
    System.out.println(rs.getObject(1));
    System.out.println(rs.getObject(2));
    System.out.println(rs.getString(3));
    System.out.println(rs.getObject(4));
}</pre>
