Laravel您要求1件物品,但只有0件物品可用

I am getting row's column randomly to seed database, using eloquent :

$physician = SelectOption::where('select_option_group_id', 1)->pluck('name')->random();

it works if data exists in select_options table. But if it does not exists, it gives an error :

You requested 1 items, but there are only 0 items available.

I want to leave it empty, if it's empty.

    Check if collection is not empty prior doing random():

    $collection = SelectOption::where('select_option_group_id', 1)->pluck('name');
    if (!$collection->isEmpty()) {
        $physician = $collection->random();
    } else {
        ...
    }
