在web程序中连接Oracle数据库的连接字符串怎么写

Answer 1

c#中连接Oracle数据库时使用的连接字符串：
var connectionString = "Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)
(HOST=192.168.115.33) (PORT=1521)))(CONNECT_DATA=(SERVICE_NAME= testDemo)));
User Id=oracle_test; Password=oracle";
其中Oracle数据库服务器IP：192.168.115.33
ServiceName：testDemo
用户名：oracle_test
密码：oracle
其他连接方法参考：http://hi.baidu.com/cntgj/blog/item/e3facd4746a085006b63e598.html

以java连接oracle为例：
1)首先要有java连接oracle数据库的驱动类,下载好后导入到工程里
2)代码:
import java.sql.*;
public class JDBCTest {
/**
* @param args
* @throws ClassNotFoundException
*/
public static void main(String[] args)
throws ClassNotFoundException, SQLException{
//1.准备参数
String ip = "192.168.0.26";
String sid = "tarena";
String port = "1521";
String dbUser = "openlab";
String dbPassword = "open123";
String driver
= "oracle.jdbc.driver.OracleDriver";

//2.构造驱动实例
Class.forName(driver);

//3.创建连接
//连接字符串是固定的形式,oracle的形式:
String url
= "jdbc:oracle:thin:@"
+ ip + ":" + port + ":" + sid;
Connection conn
= DriverManager.getConnection
(url, dbUser, dbPassword);
//4.执行SQL语句
String sql = "select id, password, name from user_sd1104 " +
"where id = 1001 and password = '1234'";
Statement stmt = conn.createStatement();
ResultSet rs
= stmt.executeQuery(sql);//执行sql语句
while(rs.next()){
int id = rs.getInt(1);
String pwd = rs.getString(2);
String name = rs.getString(3);
System.out.println("welcome," + name);
}
rs.close();
stmt.close();
conn.close();
}
}
