Schedueled Command How To Correctly Get Database Informartion By Using DB Query's

In this project users can like each other's pictures and at certain times (with a cron job that I haven't made yet) the project should automatically pick a winner ( this will be the picture with the most likes).

I've created a table in my MySQL DB that store's the post_id and the user_id of the user that liked the post. In a scheduled command, I would like to get the post_id that appears the most in the table.

I made a Laravel command do:newwinner and in its handle function, I first tested the query directly in my DB and it worked it gave me a list of all the posts with the winner on top of the list. Then I tried to implement that query in my command. But when I tried to run it it gives me errors.

This is the handle function in my do:newwinner command

public function handle()
{
    echo "start job";
    $outcome = DB::select('select post_id, COUNT(post_id) from post_user group by post_id desc');
    echo " end job".$outcome;
}

Also, the import that I used: use Illuminate\Database;

I want to be able to extract the winner from my database each time so I can store it in a winners table in my DB.

when running: php artisan do:newwinner this is the error message I get:

DB is not in your current namespace App\Console\Commands. So you can either import it at the top

use DB;

or

use Illuminate\Support\Facades\DB;

or precede it with a backslash \DB::table(...). This solves the class not found exception.
