Oracle8驱动包，极速驱动你的数据世界

Oracle8是一款开放、可扩展的大型数据管理系统，广泛应用于企业级应用中。在Oracle8的应用中，将数据库驱动包引入到项目中，能够实现对Oracle8数据库的操作。

本文将介绍如何利用Oracle8驱动包，将其引入项目中，快速连接Oracle8数据库，并进行基本的增删改查操作。

一、下载Oracle8驱动包

Oracle官网提供了Oracle8的驱动包下载，我们可以登录官网，找到相应的驱动包，选择适配的版本进行下载。

下载链接：https://www.oracle.com/database/technologies/jdbcdriver-ucp-downloads.html

二、引入驱动包

将下载的JAR包导入到项目中，在项目中新建JDBC连接，如下：

“`java

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.SQLException;

public class Mn {

public static void mn(String[] args) {

System.out.println(“——– Oracle JDBC Connection Testing ——“);

try {

Class.forName(“oracle.jdbc.driver.OracleDriver”);

} catch (ClassNotFoundException e) {

System.out.println(“Where is your Oracle JDBC Driver?”);

e.printStackTrace();

return;

}

System.out.println(“Oracle JDBC Driver Registered!”);

Connection connection = null;

try {

connection = DriverManager.getConnection(

“jdbc:oracle:thin:@localhost:1521:ORCL”, “username”,

“password”);

} catch (SQLException e) {

System.out.println(“Connection Fled! Check output console”);

e.printStackTrace();

return;

}

if (connection != null) {

System.out.println(“You made it, take control your database now!”);

} else {

System.out.println(“Fled to make connection!”);

}

}

}

其中，jdbc:oracle:thin:@localhost:1521:ORCL是连接Oracle的URL

username和password分别为所连接数据库的用户名和密码

三、基本操作

连接成功后，我们便可以进行基本的操作，如下：

查询：

```java
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
 
public class Mn {
 
   public static void mn(String[] args) {
 
       System.out.println("-------- Oracle JDBC Connection Testing ------");
 
       try {
 
           Class.forName("oracle.jdbc.driver.OracleDriver");
 
       } catch (ClassNotFoundException e) {
 
           System.out.println("Where is your Oracle JDBC Driver?");
           e.printStackTrace();
           return;
 
       }
 
       System.out.println("Oracle JDBC Driver Registered!");
 
       Connection connection = null;
       Statement statement = null;
 
       try {
 
           connection = DriverManager.getConnection(
                   "jdbc:oracle:thin:@localhost:1521:ORCL", "username",
                   "password");
 
           statement = connection.createStatement();
           String sql = "SELECT id, name, age FROM users";
           ResultSet rs = statement.executeQuery(sql);
 
           while (rs.next()) {
               System.out.println("ID: " + rs.getInt("id"));
               System.out.println("Name: " + rs.getString("name"));
               System.out.println("Age: " + rs.getInt("age"));
           }
 
       } catch (SQLException e) {
 
           System.out.println("Connection Fled! Check output console");
           e.printStackTrace();
           return;
 
       } finally {
 
           try {
 
               if (statement != null)
                   connection.close();
 
           } catch (SQLException e) {
 
               e.printStackTrace();
 
           }
       }
   }
}

插入：

“`java

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.PreparedStatement;

import java.sql.SQLException;

public class Mn {

public static void mn(String[] args) {

System.out.println(“——– Oracle JDBC Connection Testing ——“);

try {

Class.forName(“oracle.jdbc.driver.OracleDriver”);

} catch (ClassNotFoundException e) {

System.out.println(“Where is your Oracle JDBC Driver?”);

e.printStackTrace();

return;

}

System.out.println(“Oracle JDBC Driver Registered!”);

Connection connection = null;

PreparedStatement preparedStatement = null;

try {

connection = DriverManager.getConnection(

“jdbc:oracle:thin:@localhost:1521:ORCL”, “username”,

“password”);

String sql = “INSERT INTO users” +

“(id, name, age) VALUES” +

“(1, ‘张三’, 25)”;

preparedStatement = connection.prepareStatement(sql);

preparedStatement.executeUpdate();

} catch (SQLException e) {

System.out.println(“Connection Fled! Check output console”);

e.printStackTrace();

return;

} finally {

try {

if (preparedStatement != null)

connection.close();

} catch (SQLException e) {

e.printStackTrace();

}

}

}

}

同理，我们也可以进行删除和修改等操作。

综上所述，Oracle8驱动包是连接Oracle8数据库的必备工具之一。本文主要介绍如何将Oracle8驱动包引入项目中，并进行基本的增删改查操作。希望本文能够帮助大家更好地驱动数据世界。
