这篇文章主要介绍了jdbc连接oracle数据库功能,结合实例形式详细分析了java基于jdbc连接Oracle数据库的具体操作步骤与相关实现技巧,需要的朋友可以参考下
本文实例讲述了jdbc链接oracle数据库功能。分享给大家供大家参考，具体如下：
package com.sefvang.jdbc; import java.sql.Connection; import java.sql.DriverManager; import java.sql.PreparedStatement; import java.sql.ResultSet; import java.sql.sqlException; public class Db_conn { private static final String url = "jdbc:oracle:thin:@localhost:1521:orcl"; private static final String name = "system"; private static final String passwd = "sefvang"; private static final String Db_driver = "oracle.jdbc.OracleDriver"; public Connection getConnection() { Connection conn = null; try { Class.forName(Db_driver); conn = DriverManager.getConnection(url, name, passwd); if (conn != null) { System.out.println("success!!!"); } } catch (ClassNotFoundException e) { // Todo Auto-generated catch block e.printstacktrace(); } catch (sqlException e) { // Todo Auto-generated catch block e.printstacktrace(); } return conn; } public void close(Connection conn) { try { if (conn != null) { if (!conn.isClosed()) { conn.close(); } } } catch (sqlException e) { // Todo Auto-generated catch block e.printstacktrace(); } } public static void main(String[] args) { Db_conn cew Db_conn(); Connection con = conn.getConnection(); try { PreparedStatement papt = con.prepareStatement("select tname from text where tid=1"); ResultSet rs = papt.executeQuery(); if(rs.next()) System.out.println(rs.getString(1)); } catch (sqlException e) { // Todo Auto-generated catch block e.printstacktrace(); } conn.close(con); } }
希望本文所述对大家java程序设计有所帮助。
