Unions
The query builder also provides a quick way to "union" two queries together. For example, you may create an initial query and use the union method to union it with a second query:
Example(1)
app/Http/Controllers/UnionTableController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use DB;
class UnoinTableController extends Controller
{
function index()
{
$first = DB::table('users') ->whereNull('first_name');
$users = DB::table('users') ->whereNull('last_name') ->union($first) ->get();
return view('user.index', ['users' => $users]);
}
}
?>
