CREATE TABLE IF NOT EXISTS `think_data` (
  `id` int(8) unsigned NOT NULL AUTO_INCREMENT,
  `name` varchar(255) NOT NULL COMMENT '名称',
  `status` tinyint(2) NOT NULL DEFAULT '0' COMMENT '状态',
  PRIMARY KEY (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8 AUTO_INCREMENT=6 ;
INSERT INTO `think_data` (`id`, `name`, `status`) VALUES

application\index\controller\Index.php

<?php
namespace app\index\controller;
use think\Db;

class Index 
{
    public function index()
    {
        // 后面的数据库查询代码都放在这个位置
        // 插入记录
        //$result = Db::execute('insert into think_data (id, name ,status) values (5, "onestopweb",1)');
        //dump($result);
        
        // 更新记录
        //$result = Db::execute('update think_data set name = "chaoyi" where id = 5 ');
        //dump($result);
        
        // 查询数据
        //$result = Db::query('select * from think_data where id = 5');
        //dump($result);
        
        // 删除数据
        //$result = Db::execute('delete from think_data where id = 5 ');
        //dump($result);
        
        // 批量查询数据
        $result = Db::query('select * from think_data');
        dump($result);
    }
}
