SQLSTATE [HY000]:常规错误:Laravel发生2053错误 [英] SQLSTATE[HY000]: General error: 2053 error occurs at Laravel

问题描述

首先，我的环境是LAMP(M代表MariaDB).

First, my environment is LAMP(M stand for MariaDB).

整个错误是:

SQLSTATE[HY000]: General error: 2053 (SQL: UPDATE Demos SET Hit = ifnull(Hit,0) + 1 WHERE id = '27')

模型中的

代码是

code in the model is

protected function IncreaseHit($id) {
    DB::select('UPDATE Demos SET Hit = ifnull(Hit,0) + 1 WHERE id = \''.$id.'\'');
}

我想说的是这段代码在我的本地环境下运行良好. (本地环境为MAMP.)

What I want to say is this code works well at my local. (local environment is MAMP.)

在控制器上调用上述模型方法的代码是

And code that calls above model method at controller is

if(Cookie::get('My_Cookie_'.$id) != 'On'){
    Demos::IncreaseHit($id);
    Cookie::queue(Cookie::make('CS_View_'.$id, 'On',2160000));
}//Cookie Check

我找不到问题所在...请让我知道如何解决此错误.

I can't find what is wrong... Please let me know how I can fix this error.

推荐答案

使用DB::update():

DB::update('UPDATE Demos SET Hit = ifnull(Hit,0) + 1 WHERE id = ?', [$id]);

当没有任何内容可获取时，也会产生此错误.这样，使用DB::select()试图从不返回任何内容的语句中获取内容.

Also this error is produced when there's nothing to fetch. That way with DB::select() you're trying to fetch something from a statement that doesn't return anything.
