最新做了一个连接Oracle的代码,要配好环境变量: ClassPath=.;E:j2sdk14lib ools.jar;E:oracleora90jdbclibclasses12.zip 测试的电脑已经装好Oracle客户端,而且用SQLplus可以连接上。 /* * This sample shows how to list all the names from the EMP tabl

  最新做了一个连接Oracle的代码,要配好环境变量: ClassPath=.;E:j2sdk14lib ools.jar;E:oracleora90jdbclibclasses12.zip

  测试的电脑已经装好Oracle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 JDBC driver

  DriverManager.registerDriver(new oracle.jdbc.OracleDriver());

  /* try{

  Class.forName("oracle.jdbc.driver.OracleDriver");

  }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 ::. The example uses the short cut syntax.

  String url = "jdbc:oracle:thin:@172.28.31.85:1521:YIKATONG";

  String userName = "scott";

  String passWord = "tiger"; if (args.length > 0) url = args[0];

  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 ())
