Laravel 5.5 group by doesn't work - fixed

Someday ago i just installed laravel 5.5 application and i was checking new feature and making some examples. But i was working on database query builder example one by one, i got following error when i used group by on single column.

My query was like as bellow example, so you can see on database query i simple get all users and group by with name. So, let's simply see how it is:

DB Query:

$users = DB::table("users")
            ->groupBy("name")
            ->get();
dd($users);

But when i run above query using database query builder i got following error, as you can see:

SQLSTATE[42000]: Syntax error or access violation: 1055 'laravel_test.users.id' isn't in GROUP BY (SQL: select * from `users` group by `name`)

I was thinking what is the issue because without group by it was working, but at last i found it how to solve it So we have to simply "strict" mode make it true into false in database.php file. So let's do it as bellow:

config/database.php

...
'strict' => true,

To

'strict' => false,
....

After that i hope you found your solution.

Thank you...
