I have been unsuccessfully trying to leftjoin and get the required data
Here is my code:
$album = Albums::->where('users_id',$user_id)
->leftJoin('photos',function($query){
$query->on('photos.albums_id','=','albums.id');
$query->where('photos.status','=',1);
//$query->limit(1);
//$query->min('photos.created_at');
})
->where('albums.status',1)->get();
The comments are some of my several trying...
I want to get only a single record from the photos table matching the foreign key album_id
which was updated first and also with status 1
pls help...
I have used DB::raw()
in order to achieve this
$album = Albums::select( 'albums.*',
DB::raw('(select photo from photos where albums_id = albums.id and status = 1 order by id asc limit 1) as photo') )
->where('users_id',$user_id)
->where('albums.status',1)->get();
@JarekTkaczyk 's coding was similar and displayed the same result as I needed, so a special thanks to him for his time and effort...
But comparing the execution time for the quires
I stayed to mine as my above snippet
select `albums`.*, (select photo from photos where albums_id = albums.id and status = 1 order by id asc limit 1) as photo from `albums` where `users_id` = '1' and `albums`.`status` = '1'
took 520μs - 580μs
and @JarekTkaczyk 's
select `albums`.*, `p`.`photo` from `albums` left join `photos` as `p` on `p`.`albums_id` = `albums`.`id` and `p`.`created_at` = (select min(created_at) from photos where albums_id = p.albums_id) and `p`.`status` = '1' where `users_id` = '1' and `albums`.`status` = '1' group by `albums`.`id`
took 640μs - 750μs
But both did the same...
