| 参考 http://java.sun.com/docs/books/tutorial/jdbc/basics/index.html java中操作Oracle数据库,经过以下几个步骤, 1.将OracleHome/jdbc/lib/目录的所有文件添加到jre/lib/ext目录;(配置JDBC驱动) 2.创建odbc源,在控制面板=》管理工具=》数据源(odbc)中添加DSN,比如取名为OracleDSN,选择一个Service,输入用户名密码,测试连接,若通过说明成功; 3.在程序中加载jdbc驱动(下面的例子用的是JdbcOdbc驱动),建立连接,执行Query. 下面是连接OracleDSN ODBC data source的一个类,方法Test()连接数据库后,读取tbljob的内容,并显示所有记录。 import java.sql.*; class OracleConnect { public static void Test() { //connection by JdbcOdbcDriver try { //load the driver: Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
//connect the Database,OracleDSN is the ODBC data source ; String url = "jdbc:odbc:OracleDSN"; Connection conn = DriverManager.getConnection(url, "system", "system_passwd"); // Create a Statement Statement stmt = conn.createStatement(); // Select first_name and last_name column from the employees table ResultSet rset = stmt.executeQuery("select * from tbljob;"); // Iterate through the result and print the employee names while (rset.next()) System.out.println(rset.getString(1) + " " + rset.getString(2)); // Close the RseultSet2 rset.close(); // Close the Statement stmt.close(); // Close the connection conn.close(); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } } }
