$stores = Stores::select('id','name')->whereNotIn('id', function ($query) use($id){
            $query->select('stores_id')->from('fook_article_stores')->where('fook_article_stores.article_id', $id);
        })->get();

Stores::where('verification_pass',$verification_pass)->where('id','<>',$id)->where('business_id', function ($query) use($id){
                $query->select('business_id')->from('fook_stores')->where('fook_stores.id', $id);

高效写法blog

$users = User::whereNotIn('id', function ($query) use($user){
            $query->select('toUserId')->from('relation')->where('relation.userId', $user->id);
});

低效率写法

$actionRelationsArray = Relation::select('toUserId')->where('userId', $user->id)->get()->pluck('toUserId');
$users = User::whereNotIn('id', $actionRelationsArray);
