php - Eloquent groupBy make "SQLSTATE[42000]" with valid SQL query in Laravel 5.3

Question

I have a strange problem with Eloquent which I'm trying to do the following:

$this->node = DB::table('permission')
                ->select('permission.id',
                         'object.name as object_name',
                         'permission.created_at',
                         'object.id as object_id')
                ->join('object', 'object.id', '=', 'permission.object_id')
                ->join('action', 'action.id', '=', 'permission.action_id')
                ->where('permission.person_id', $this->person['id'])
                ->groupBy('permission.object_id')
                ->orderBy('permission.created_at', 'desc')
                ->paginate(5);

Laravel Framework report an Error:

QueryException in Connection.php line 761: SQLSTATE[42000]: Syntax error or access violation: 1055 'permission.id' isn't in GROUP BY (SQL: select permission.id, object.name as object_name, permission.created_at, object.id as object_id from permission inner join object on object.id = permission.object_id inner join action on action.id = permission.action_id where permission.person_id = 1 group by permission.object_id order by permission.created_at desc limit 5 offset 0)

I've added an Eloquent debugging function DB::listen in AppServiceProvider:

use IlluminateSupportFacadesDB;
use IlluminateSupportServiceProvider;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        //
         DB::listen(function ($query) {

            echo "<pre>";
            print_r($query->sql);
            echo "</pre>";

            // $query->sql
            // $query->bindings
            // $query->time
        });
    }
    ...

And it does print this SQL query:

select  `permission`.`id`, 
        `object`.`name` as `object_name`, 
        `permission`.`created_at`, 
        `object`.`id` as `object_id` 
from `permission` 
inner join `object` on `object`.`id` = `permission`.`object_id` 
inner join `action` on `action`.`id` = `permission`.`action_id` 
where `permission`.`person_id` = 1 
group by `permission`.`object_id` 
order by `permission`.`created_at` desc 
limit 5 offset 0

Which is valid in MySQL through PhpMyAdmin and here is the output for the query: Even So, I tested in mysql command directly and it does work just fine, look at mysql output:

Any idea?

Thanks

Answer 1

Faced same problem with laravel 5.3 They are trying to enforce strict query writing came with mysql-5.7

However to disabled this just go to config/database.php and change strict flag

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

Hope this will solve your problem too.

PS - For details on strict query writing refer to @Shadow's answer
