I have a query with sub-query .. and i want to write an explicite SQL request and execute it Query :
select count(*) as count from
(
SELECT DISTINCT t.article_id FROM
`articles` as a left join `tags` as t
on a.`id` = t.`article_id`
where a.`flag` = 1
) as sub
i tried this to execute the request without building the query :
DB::connection()->getPdo()->exec( $sql );
But it always return 0 !
You can use sub query with DB::raw. A method DB::raw() (don’t forget to use Illuminate\Support\Facades\DB) allows you to select whatever you want and basically write raw SQL statements.
DB::select(DB::raw("select count(*) as count from
(
SELECT DISTINCT t.article_id FROM
`articles` as a left join `tags` as t
on a.`id` = t.`article_id`
where a.`flag` = 1
) as sub"));
Why don't you try with DB::raw('your sql query here')
Using DB::select should solve your problem.
DB::select('select count(*) as count from
(
SELECT DISTINCT t.article_id FROM
`articles` as a left join `tags` as t
on a.`id` = t.`article_id`
where a.`flag` = 1
) as sub');
