How can I change "join with select statement results to" laravel eloquent? - sql

Question

My query like this :
SELECT
*
FROM
(SELECT ks, COUNT(*) AS '# Tasks' FROM Table GROUP BY ks) t1
INNER JOIN
(SELECT ks, COUNT(*) AS '# Late' FROM Table WHERE Age > Palt GROUP BY ks) t2
ON t1.ks = t2.ks
I want to change it to laravel eloquent. I need to using paginate method from laravel eloquent
I try like this :
$query = \DB::select(\DB::raw("
SELECT *
FROM (
SELECT ks, COUNT(*) AS '# Tasks' FROM Table GROUP BY ks
) t1
INNER JOIN (
SELECT ks, COUNT(*) AS '# Late' FROM Table WHERE Age > Palt GROUP BY ks
) t2 ON t1.ks = t2.ks
"));
I'm confused to put paginate method. I need it. Because I want display pagination in view blade laravel
The script like this : {{ $results->appends(Request::query())->render() }}
How can I do it?

Firstly, based on the linked question from which you sourced your database schema, the data you are attempting to query can be found using a far simplier query.
I have written the following query for use on a MySQL DBMS, as neither your, nor the linked question specify a DBMS type.
SELECT ks, COUNT(*) AS tasks, SUM(age < palt) AS late
FROM tasks
GROUP BY ks;
Here's an SQL Fiddle with sample data demonstrating the query works.
Secondly, the aforementioned query can be built using the Laravel query builder as follows.
$results = DB::table('tasks')
->selectRaw('ks, COUNT(*) AS tasks, SUM(age < palt) AS late')
->groupBy('ks')
->paginate(10);
