连接mysql的字符串

连接mysql的字符串，注意使用细节。

Connection=

("jdbc:mysql://localhost:3306/dataname","root","password")

举例1：

连接字符串

MySqlConnection conn = new MySqlConnection("User Id=root;Password=sa;Host=localhost;Database=mis;");

conn.Open();

MySqlDataAdapter da = new MySqlDataAdapter("select id, name, age from `mis`.`users` ",conn);

DataSet ds = new DataSet();

da.Fill(ds,"users");

conn.Close();

DataGrid1.DataSource= ds;

DataGrid1.DataBind();

举例2：

package com;

import java.sql.*;

public class ssss {

public static void main(String args[]) {

try {

Class.forName("org.gjt.mm.mysql.Driver");

//加载MYSQL JDBC驱动程序

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/student", "root", "123");

// 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 teststudent");

while (rs.next()) {

System.out.println(rs.getString("sn")+"---"+rs.getString("ss"));

}

}

catch (Exception e) {

System.out.print("get data error!");

e.printStackTrace();

}

}

}
