How to use pagination with laravel DB::select query - php

Question

I am working on a project in Laravel and using DB facade to run raw queries of sql.
In my case I am using DB::select, problem is that pagination method is not working with this DB raw query and showing this error
Call to a member function paginate() on array
I just want how to implement laravel pagination with DB raw queries
here is my code:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Notice;
use Illuminate\Support\Facades\DB;
use Illuminate\Pagination\Paginator;
use Illuminate\Pagination\LengthAwarePaginator;
class NoticeController extends Controller
{
public function index(){
$notices = DB::select('select
notices.id,notices.title,notices.body,notices.created_at,notices.updated_at,
users.name,departments.department_name
FROM notices
INNER JOIN users ON notices.user_id = users.id
INNER JOIN departments on users.dpt_id = departments.id
ORDER BY users.id DESC')->paginate(20);
$result = new Paginator($notices,2,1,[]);
return view('welcome')->with('allNotices', $notices);
}
}

Answer 1

Try:
$notices = DB::table('notices')
->join('users', 'notices.user_id', '=', 'users.id')
->join('departments', 'users.dpt_id', '=', 'departments.id')
->select('notices.id', 'notices.title', 'notices.body', 'notices.created_at', 'notices.updated_at', 'users.name', 'departments.department_name')
->paginate(20);

Answer 2

public function index(Request $request){
$notices = DB::select('select notices.id,notices.title,notices.body,notices.created_at,notices.updated_at,
users.name,departments.department_name
FROM notices
INNER JOIN users ON notices.user_id = users.id
INNER JOIN departments on users.dpt_id = departments.id
ORDER BY users.id DESC');
$notices = $this->arrayPaginator($notices, $request);
return view('welcome')->with('allNotices', $notices);
}
public function arrayPaginator($array, $request)
{
$page = Input::get('page', 1);
$perPage = 10;
$offset = ($page * $perPage) - $perPage;
return new LengthAwarePaginator(array_slice($array, $offset, $perPage, true), count($array), $perPage, $page,
['path' => $request->url(), 'query' => $request->query()]);
}

Don't ever use the pagination logic on php-side!
Use limit and offset on your sql's and leave the rest to the database server.
Additional use a seperate count-select for your statement.
Count:
$sql_count = 'SELECT count(1) cnt FROM ('. $sql . ') x';
$result = \DB::select( DB::raw($sql_count) );
$data['count'] = $result[0]->cnt;
Results:
$sql .= ' LIMIT ' . $offset . ', ' . $limit;
$result = \DB::select( DB::raw($sql) );
$myPaginator = new \Illuminate\Pagination\LengthAwarePaginator($result, $data['count'], $limit, $page, ['path' => action('MyController#index')]);
$data['result'] = $result;

Answer 4

This is suitable for me
$sql = "some sql code";
$page = 1;
$size = 10;
$data = DB::select($sql);
$collect = collect($data);
$paginationData = new LengthAwarePaginator(
$collect->forPage($page, $size),
$collect->count(),
$size,
$page
);

Answer 5

It work for me, see
First use in your controller
use Illuminate\Pagination\Paginator;
then in function
$query = DB::select(DB::raw("SELECT pro.* , (SELECT TIMESTAMPDIFF(DAY,updated_at,'$current_date') from users as u where u.id=pro.id) as days FROM users as pro where role_id = 6 and delete_status=0 and user_status = 'A' and approved_status = 1 and is_clever_courier = 1 having days >= 5"));
$page1 = new Paginator($query, $maxPage);
dd($page1);
o/p =>
Paginator {#1450 ▼
#hasMore: true
#items: Collection {#1509 ▼
#items: array:10 [▼
0 => {#1454 ▶}
1 => {#1455 ▶}
2 => {#1456 ▶}
3 => {#1457 ▶}
4 => {#1458 ▶}
5 => {#1459 ▶}
6 => {#1460 ▶}
7 => {#1461 ▶}
8 => {#1462 ▶}
9 => {#1463 ▶}
]
}
#perPage: 10
#currentPage: 1
#path: "/"
#query: []
#fragment: null
#pageName: "page"
+onEachSide: 3
#options: []

After trying so many things I found the solution and it works fine for me, maybe it will be helpful for someone else.
First, in a PHP class use Illuminate\Pagination\LengthAwarePaginator:
use Illuminate\Pagination\LengthAwarePaginator;
public function index(Request $request) {
$notices = DB::select('SELECT notices.id, notices.title, notices.body, notices.created_at, notices.updated_at, users.name,departments.department_name
FROM notices
INNER JOIN users ON notices.user_id = users.id
INNER JOIN departments on users.dpt_id = departments.id
ORDER BY users.id DESC');
$notices = $this->arrayPaginator($notices, $request);
return view('welcome')->with('allNotices', $notices);
}
public function arrayPaginator($array, $request) {
$page = Input::get('page', 1);
$perPage = 10;
$offset = ($page * $perPage) - $perPage;
return new LengthAwarePaginator(
array_slice(
$array,
$offset,
$perPage,
true
),
count($array),
$perPage,
$page,
['path' => $request->url(), 'query' => $request->query()]
);
}

Answer 7

this work for me ... and good for performance :
query for count all results.
query for main query with offset and limit.
make paginate for current items based on page number.
$sql_count = "select count(*) as aggregate from `products`";
$data_count = DB::select($sql_count);
$count = $data_count[0]->aggregate;
$per_page =10; //define how many items for a page
$pages = ceil($count/$per_page);
$page = ($request->page=="") ?"1" :$request->page;
$start = ($page - 1) * $per_page;
$sql = "select * from `products`";
$sql.= ' LIMIT ' . $start . ', ' . $per_page;
$page = 1;
$size = 10;
$data = DB::select($sql);
$data = $this->paginate($data , $count , $per_page , $request->page);
public function paginate($items, $total , $perPage = 5, $page = null, $options = [])
{
$page = $page ?: (Paginator::resolveCurrentPage() ?: 1);
$items = $items instanceof Collection ? $items : Collection::make($items);
return new LengthAwarePaginator($items, $total, $perPage, $page, $options);
}
