ORACLE的JDBC简单写法

 

Class.forName("oracle.jdbc.driver.OracleDriver"); // 加载驱动器的类

String url = "jdbc:oracle:thin:@localhost:dbname";

String user = "test";

String password = "test";

conn = DriverManager.getConnection(url, user, password);

 

String sql = "select * from test_tb";

  try {

   PreparedStatement ps = con.prepareStatement(sql);

   ResultSet rs = ps.executeQuery();

   if (rs.next()) {

    System.out.println(rs.getString(1));

   }

  } catch (SQLException e) {

   // TODO Auto-generated catch block

   e.printStackTrace();

  }
