测试的电脑已经装好Oracle(大型网站数据库平台)客户端,而且用SQLplus可以连接上。
/*
* This sample shows how to list all the names from the EMP table
*
* It uses the JDBC THIN driver. See the same program in the
* oci8 samples directory to see how to use the other drivers.
*/

// You need to import the java.sql package to use JDBC
import java.sql.*;

class Test
{
 public static void main (String args [])
    throws SQLException
 {
  // Load the Oracle(大型网站数据库平台) JDBC driver
  DriverManager.registerDriver(new Oracle(大型网站数据库平台).jdbc.Oracle(大型网站数据库平台)Driver());
/* try{
 Class.forName("Oracle(大型网站数据库平台).jdbc.driver.Oracle(大型网站数据库平台)Driver");
}catch(Exception e){
 System.out.println("No Driver!");
}
*/
  // Connect to the database
  // You must put a database name after the @ sign in the connection URL.
  // You can use either the fully specified SQL*net syntax or a short cut
  // syntax as <host>:<port>:<sid>. The example uses the short cut syntax.
  String url = "jdbc:Oracle(大型网站数据库平台):thin:@172.28.31.85:1521:YIKATONG";
  String userName = "scott";
  String password = "tiger";

if (args.length > 0) url = args[0];
  if (args.length > 1) userName = args[1];
  if (args.length > 2) password = args[2];
System.out.println(url);
System.out.println(userName);
System.out.println(password);
  Connection conn =
   DriverManager.getConnection (url, userName, password);

// Create a Statement
  Statement stmt = conn.createStatement ();

  // Select the ENAME column from the EMP table
  ResultSet rset = stmt.executeQuery ("select * from Test");

// Iterate through the result and print the employee names
  while (rset.next ())
   System.out.println (rset.getString (1));
 }
}
