Example 1: how to get data from a table in laravel

use Illuminate\Support\Facades\DB;

class UserController extends Controller
{
    public function index()
    {
        $users = DB::table('users')->select('id','name','email')->get();

        return view('some-view')->with('users', $users);
    }
}

DB::table(..)->select(..)->whereNotIn('book_price', [100,200])->get();

            ->whereNull('last_name')
            ->union($first)
            ->get();
