用Eclipse连接MySQL数据库的步骤

mysql>CREATE DATABASE test;  //创建一个数据库 
mysql>use test; //指定test为当前要操作的数据库 
mysql>CREATE TABLE user (name VARCHAR(20),password VARCHAR(20));  //创建一个表user，设置两个字段。 
mysql>INSERT INTO user VALUES('huzhiheng','123456'); //插入一条数据到表中 

import java.sql.*; 
public class MysqlJdbc { 
 public static void main(String args[]) { 
  try { 
   Class.forName("com.mysql.jdbc.Driver");   //加载MYSQL JDBC驱动程序  
   //Class.forName("org.gjt.mm.mysql.Driver"); 
   System.out.println("Success loading Mysql Driver!"); 
  } 
  catch (Exception e) { 
   System.out.print("Error loading Mysql Driver!"); 
   e.printStackTrace(); 
  } 
  try { 
   Connection connect = DriverManager.getConnection( 
     "jdbc:mysql://localhost:3306/test","root","198876"); 
      //连接URL为  jdbc:mysql//服务器地址/数据库名 ，后面的2个参数分别是登陆用户名和密码 
 
   System.out.println("Success connect Mysql server!"); 
   Statement stmt = connect.createStatement(); 
   ResultSet rs = stmt.executeQuery("select * from user"); 
                               //user 为你表的名称 
   while (rs.next()) { 
    System.out.println(rs.getString("name")); 
   } 
  } 
  catch (Exception e) { 
   System.out.print("get data error!"); 
   e.printStackTrace(); 
  } 
 } 
} 

Success loading Mysql Driver! 
Success connect Mysql server!

mysql> show tatabases; //查看所数据库 
mysql> use test;  //使test为当前要操作的数据库 
mysql> show tables; //查看当前数据库的所有表 
view sourceprint? 
mysql> select *from user; //查看当前表（user）的所有信息
