The content of this article is about the method (code) of using native MySQL statements in TP. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

Recently I was developing a project in Thinkphp and wanted to use native MySQL statements. I finally tried it and found it particularly helpful for complex query and update operations! Let’s introduce it in detail below!

1. Use the native mysql core

$Model = M();        
$result = $Model->query($sql);//查询
$Model->execute($sql_ex);//更新修改删除

Copy after login

2. Specific usage

  <?php
    /**
     * 一亩地
     */
    public function dealYimudi(){
        $sql = "SELECT * from yimudi y LEFT JOIN yimudi_use yu on y.yimudi_id =yu.yimudi_id WHERE  yu.yimudi_id = 12 and yu.use_status in (1,2) and y.use_end_time+86399 < UNIX_TIMESTAMP(now())";

        $Model = M();
        $result = $Model->query($sql);

        $yimudi_ids =[];
        foreach ($result as $key => $value) {
            $yimudi_ids[] =$value[&#39;id&#39;];
        }
        foreach ($result as $key1 => $value1) {
           if(in_array($value1[&#39;id&#39;],$yimudi_ids)){
            $str_yimudi_id = $value1[&#39;id&#39;];
            $sql_ex = "update yimudi_use set use_status = 6 where id = &#39;$str_yimudi_id&#39;";

              $Model->execute($sql_ex);

           }
        }
        // $result = $Model->query($sql);
        // dump($result);die;
    }

Copy after login

You can try it!
