jAvA连接OrAClE数据库

Connection conn = null; Class.forName("oracle.jdbc.driver.OracleDriver");//加入oracle的驱动,“”里面是驱动的路径 String url = "jdbc:oracle:thin:@MyDbComputerNameOrIP:1521:ORCL";// 数据库连接,oracle代表链接的是oracle数据库;thin...

//1.加载驱动 Class.forName("oracle.jdbc.driver.OracleDriver"); //需要下载oracle JDBC的驱动包 //2.得到链接 String url = "jdbc:oracle:thin:@localhost:1521:orcl"; //数据库URL,orcl是我的数据库的名称 String user = "myuser"; //你ORA...

public static ResultSet oracleConn(String sql) { String driver = "oracle.jdbc.driver.OracleDriver"; //写明你数据的连接串 String url = "jdbc:Oracle:thin:@192.168.1.1:3004/xe"; Statement stmt = null; ResultSet res = null; Connect...

你在prepardstatement里面只有一个问号 在下面的时候 怎么却提供了4个值给他 很显然不可以的嘛 要么你就再加三个问号 insert into reader values(? , ? , ? , ?) 这才像点样 这错误太低级了

Class.forName: oracle.jdbc.driver.OracleDriver URL: jdbc:oracle:thin:@localhost:1521:orcl

我先给你连接数据库的类吧! 步骤1 package test.procedure; import java.sql.Connection; import java.sql.DriverManager; import java.sql.SQLException; public class ConnectOrcl { String driver,url,user,pwd; public ConnectOrcl(){ driv...

一个最简单连接oracle的例子 package oracletest; import java.sql.Connection; import java.sql.DriverManager; import java.sql.ResultSet; import java.sql.SQLException; import java.sql.Statement; public class OracleTest { public stat...

多加一个address就可以了,代码如下: instance = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 1_1)(PORT = 1521)) (ADDRESS = (PROTOCOL = TCP)(HOST = 1_2)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = orac...

import java.sql.*; public class getMetaData { public static void main(String[] args) { String driverClassName = "oracle.jdbc.OracleDriver"; String url = "jdbc:oracle:thin:@192.101.101.101:1521:orcl"; String password = "test"; S...

Oracle 的 Listener是必须要启动的,如果你用客户端(如: sqlplus 或 toad 等)能够连上Oracle,则说明Oracle是正常的了。 java这方面的错误,你需要把错误的提升贴上来才行,否则也不好说是什么问题。 另外,关于URL的写法, jdbc:oracle:thin...
