Laravel Eloquent Builder中的GroupBy错误 [英] GroupBy Error in Laravel Eloquent Builder

问题描述

我不想相信laravel 5.5 cos中有一个错误，当我在查询中使用groupBy时，我如何惊讶地在Eloquent Query Builder上出现错误.

I dont want to believe there is a bug in laravel 5.5 cos i am amazed how i keep getting errors on the Eloquent Query Builder when ever i use the groupBy in my query.

试图将此无缝运行的SQL转换为Eloquent，并且我在groupBy上不断收到错误消息.

Tried converting this SQL that works seamlessly to Eloquent and i keep getting Errors on the groupBy..

我在这里抱怨过一个类似的SQL问题，直到现在我还没有一个完美的答案此处未解决问题

Had a similar issue with an SQL which i complained here and till now i have not gotten a perfect answer for it open issue here

SELECT * FROM arm_articles
    INNER JOIN arm_interest ON arm_articles.article_category = arm_interest.category_id 
    WHERE arm_articles.article_contributor_id='1322' 
    GROUP BY arm_articles.article_id

返回错误的电子版本

$contributor_id =1322;
DB::table('arm_articles')
->join('arm_interest', function($join) {
    $join->on('arm_articles.article_category','=','arm_interest.category_id');
})
->having('arm_articles.article_contributor_id', '=', $contributor_id)
->groupBy('arm_articles.article_id')->get()

错误消息

SQLSTATE [42000]:语法错误或访问冲突:1055'knowledge_db.arm_articles.id'不在GROUP BY中(SQL:从'arm_articles'内部联接'arm_articles'的内部联接'arm_interest'中选择*.'article_category'='arm_interest'.'category_id'由'arm_articles'.'article_id'具有'arm_articles'.'article_contributor_id'= 1322)分组

因此，就像我说的b4一样，为什么我会因为首先向查询中添加-> toSql 而返回正确的SQL的原因而感到头疼.

So like i said b4 its really weared why i will get the error in the first place as adding ->toSql to the query returns the right SQL.

推荐答案

• 将此配置添加到 config/database.php 中的mysql数据库配置中:

  • Add this configuration to your mysql database config in config/database.php:

       'mysql' => [
            ....
            'strict' => false,
            //'strict' => true,
        ],
    

  • 在您的mysql配置文件( my.ini 或 my.cnf )中编辑 sql_mode [mysqld]

  • Edit sql_mode in your mysql config file (my.ini or my.cnf) [mysqld]

    sql_mode = STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
    

  • 重新启动MySQL

  • Restart your MySQL
