java插入oracle

⑴ 怎麼用java連接oracle資料庫，需要詳細解釋

1)首先你要有java連接oracle資料庫的驅動類,下載好後導入到工程里

2)代碼:
import java.sql.*;

public class JDBCTest {

/**
* @param args
* @throws ClassNotFoundException
*/
public static void main(String[] args)
throws ClassNotFoundException, SQLException{
//1.准備參數
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.構造驅動實例
Class.forName(driver);

//3.創建連接
//連接字元串是固定的形式,oracle的形式:
String url
= "jdbc:oracle:thin:@"
+ ip + ":" + port + ":" + sid;
Connection conn
= DriverManager.getConnection
(url, dbUser, dbPassword);
//4.執行SQL語句
String sql = "select id, password, name from user_sd1104 " +
"where id = 1001 and password = '1234'";
Statement stmt = conn.createStatement();
ResultSet rs
= stmt.executeQuery(sql);//執行sql語句
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();
}

}
