如何在Laravel中使用DB :: select联合查询进行分页

Question

在我的项目中，我已将 DB：select 与UNION 六个表和 ORDER BY 一起使用。如何在Laravel框架中向此查询添加分页？

我已经尝试过使用Laravel文档分页，但是使用六个表的UNION查询无法分页。

public function publishAds()
{
    $id = Auth::user()->id;
    $data = City::all();
    $ads = DB::select("(SELECT id,title,updated_at,'Commercial Properties' as 
        'type',town,city,rent_per_month,image1,add_status,'commercial_properties' as 
        tableName,type as adType  from commercial_properties WHERE add_status='published' 
        AND user_id=$id) union (select id,title,updated_at,'House',town,city,rent_per_month,
        image1,add_status,'houses',type from houses WHERE add_status='published' 
        AND user_id=$id ) union (select id,title,updated_at,'Land',town,city,rent_per_month,
        image1,add_status,'lands',type from lands WHERE add_status='published' 
        AND user_id=$id ) union (select id,title,updated_at,'Apartment',town,city,
        rent_per_month,image1,add_status,'apartments',type from apartments 
        WHERE add_status='published' AND user_id=$id ) union (select id,title,updated_at,
        'Holyday Rental',town,city,rent_per_month,image1,add_status,'holyday_rentals',
        type from holyday_rentals WHERE add_status='published' AND user_id=$id ) union 
        (select id,title,updated_at,'Room',town,city,rent_per_month,image1,add_status,
        'rooms',type from rooms WHERE add_status='published' AND user_id=$id ) order 
        by updated_at DESC,rand()");

    return view('admin/my-add', ['ads' => $ads, 'cities' => $data, 'status' => 'Publish Ads']);
}

我想为包含六个UNION的该查询分页。
