Question

这是我正在尝试的代码- ORACLE驱动程序已成功加载，但获得了该语句的连接-

public class OracelConn {
   public static void main(String[] args) throws Exception {
      try {
         try {
            Class.forName("oracle.jdbc.driver.OracleDriver");
         } catch (ClassNotFoundException e) {
            System.out.println("Please include Classpath  Where your ORACLE Driver is located");
            e.printStackTrace();
            return;
         }
         System.out.println("ORACLE driver is loaded successfully");
         Connectioncon=DriverManager.getConnection( "jdbc:oracle:thin:or0132p.exg.com:1521:OP0132.exg.com", "wsteam", "wsteam");

         Statement stmt = con.createStatement();
         ResultSet rs = stmt.executeQuery("select TC_ORDER_ID from orders where tc_order_id='0296906379'");
         while (rs.next())
            System.out.println(rs.getString("TC_ORDER_ID"));

         con.close();
         } catch (Exception e) {
             System.out.println(e);
         }
      }
   }

您的URL格式似乎有问题。以下是受支持的格式：

如果您有SID，请使用以下（较旧的）格式：

jdbc:oracle:thin:@[HOST][:PORT]:SID

如果您有Oracle服务名称，请使用以下（较新的）格式：

jdbc:oracle:thin:@//[HOST][:PORT]/SERVICE
