I just need to order my records according to updated, and then group them according to card_id.
This is my code:
$triages = Triyage::latest('updated_at')->groupBy('card_id')->paginate(8);
return view('Admin.Opd.card_opd', compact('triages'));
Use a subquery JOIN:
$join = Triyage::select('card_id', DB::raw('max(updated_at) updated_at'))
->groupBy('card_id');
$sql = '(' . $join->toSql() . ') as latest';
$triages = Triyage::join(DB::raw($sql), function($join) {
$join->on('triyages.card_id', 'latest.card_id')
->on('triyages.updated_at', 'latest.updated_at');
})->paginate(8);

I have a complicated query that I would like to translate either in Eloquent ORM or with the Query Builder for a Laravel site, but I can't do it, can someone help me?
Here is my SQL query
SELECT opp_id, risk_study.rst_id, risk_study.rst_status
FROM opportunity
LEFT JOIN risk_study ON risk_study.rst_id =
(SELECT risk_study_quote_vehicle.rst_id
FROM risk_study_quote_vehicle
INNER JOIN quote_vehicle ON quote_vehicle.quv_id = risk_study_quote_vehicle.quv_id
INNER JOIN quote ON quote.quo_id = quote_vehicle.quo_id
WHERE quote.opp_id = opportunity.opp_id
ORDER BY risk_study_quote_vehicle.rst_id DESC
LIMIT 0,1)
WHERE 1 = 1
AND opportunity.per_id_process = '5'
AND opportunity.opp_locked = '1'
Here is my solution.
But this query does not retrieve values from the risk_study table.
$opportunities = Opportunity::select('opp_id', 'risk_study.rst_id', 'risk_study.rst_status')
->leftJoin('risk_study', function ($join) {
$join->on('risk_study.rst_id', '=', DB::raw('"SELECT risk_study_quote_vehicle.rst_id FROM risk_study_quote_vehicle INNER JOIN quote_vehicle ON quote_vehicle.quv_id = risk_study_quote_vehicle.quv_id INNER JOIN quote ON quote.quo_id = quote_vehicle.quo_id WHERE quote.opp_id = opportunity.opp_id ORDER BY risk_study_quote_vehicle.rst_id DESC LIMIT 0,1"'));
})
->where([
['per_id_process', 5],
['opp_locked', 1],
])
->get();
Finally, I wrote the query and it works ! Thanks !
$opportunities = Opportunity::query()
->select(
'opp_id',
'risk_study.rst_id',
'risk_study.rst_status'
)
->from('opportunity')
->leftJoin('risk_study', function ($join) {
$join->where('risk_study.rst_id', function ($sub) {
$sub->select('risk_study_quote_vehicle.rst_id')
->from('risk_study_quote_vehicle')
->join('quote_vehicle', 'quote_vehicle.quv_id', 'risk_study_quote_vehicle.quv_id')
->join('quote', 'quote.quo_id', 'quote_vehicle.quo_id')
->whereColumn('quote.opp_id', 'opportunity.opp_id')
->orderByDesc('risk_study_quote_vehicle.rst_id')
->limit(1);
});
})
->where('opportunity.per_id_process', '5')
->where('opportunity.opp_locked', '1')
->get();
You should be able to use a Closure as the second parameter of where() inside your join Closure.
I don't think Laravel's query builder supports the LIMIT 0,1 statement.
I don't know why you need WHERE 1 = 1, but you should be able to use whereRaw for that.
When you're done, the result looks very alike a formatted SQL query.
$opportunities = Opportunity::query()
->select(
'opp_id',
'risk_study.rst_id',
'risk_study.rst_status'
)
->from('opportunity')
->leftJoin('risk_study', function ($join) {
$join->where('risk_study_quote_vehicle.rst_id', function ($sub) {
$sub->select('risk_study_quote_vehicle.rst_id')
->from('risk_study_quote_vehicle')
->join('quote_vehicle', 'quote_vehicle.quv.id', 'risk_study_quote_vehicle.quv_id')
->join('quote', 'quote.quo_id', 'quote_vehicle.quo_id')
->where('quote_opp_id', 'opportunity.opp_id')
->orderByDesc('risk_study_quote_vehicle.rst_id')
->limit(1);
});
})
->whereRaw('1 = 1')
->where('opportunity.per_id_process', '5')
->where('opportunity.opp_locked', '1')
->get();
Hi I want to know how can i do this query in Laravel 8 , I tried adding the join clause but not work as expected, i need join clause? Or maybe there is another form to do it. I search others examples but i don´t see anythat help me. The query is the next:
DB::table('escandallo_p as esc')
->select("esc.material", "esc.referencia", "esc.ancho", "esc.proveedor", "esc.punto",
"esc.precio", "esc.consumo", "esc.veces", "esc.001", "esc.002", "esc.003", "esc.004",
"esc.005", "esc.006", "esc.007", "esc.008", "esc.009", "esc.010", "esc.011", "esc.um", "esc.merma", "esc.importe", "esc.tipo", "esc.xtalla", "esc.fase",
DB::raw("(select anulado from prototipos_p as p where p.prototipo = '".$scandal[0]->prototipo."' and p.tipo = 'c' and p.referencia = esc.referencia )"),
// ignore
//original query "(select anulado from prototipos_p as p where p.prototipo = ",$request->prototipo," and p.tipo = 'c' and p.referencia = esc.referencia ) as 'anulado'",
// "(select clase from prototipos_p as p where p.prototipo = ",$request->prototipo," and p.tipo = 'c' and p.referencia = esc.referencia ) as 'clase'")
//Converted query ->select('pro.anulado')->where('pro.prototipo', $request->prototipo)
// ->where("p.prototipo", "=", $request->prototipo)
->where("esc.id_escandallo", "=", $request->id_escandallo)
->where("esc.id_version", "=", $request->version)
->orderBy("id","asc")
->get();
!!!! I need to pass the esc.referencia to the sub select query
The second select is the conversion of the select inside "" ( i know this is wrong is only for explain it).
Thank you in advance for any suggestion.
Best regards
EDIT: I can solve my problem with DB::raw, but if anyone know others methos are welcome!
You need to pass callback to the join query to add the extra query to the laravel's join method,
Example from Laravel Doc:
DB::table('users')
->join('contacts', function ($join) {
$join->on('users.id', '=', 'contacts.user_id')
->where('contacts.user_id', '>', 5);
})
->get();
It is explained in Laravel's doc, Advanced Join Clauses
There is Subquery support too Subquery Joins,
Eg:
$latestPosts = DB::table('posts')
->select('user_id', DB::raw('MAX(created_at) as last_post_created_at'))
->where('is_published', true)
->groupBy('user_id');
$users = DB::table('users')
->joinSub($latestPosts, 'latest_posts', function ($join) {
$join->on('users.id', '=', 'latest_posts.user_id');
})
->get();
These two might help you to achieve what you are trying
After test joins, joinSub, whereIn and other forms of doing this, I solved my problem using the DB::raw():
DB::table('escandallo_p as esc')
->select('parameters',....,
DB::raw("(SELECT column //(ONLY ONE)
FROM table
WHERE column = '".$parameter."' ...) AS nombre"),
)
->where('column', "=", $parameter)
->orderBy("id","asc")
->get();
I would like to reproduce following mySQL query using Laravel query builder:
*SELECT SUM(scores) FROM (SELECT scores FROM player_games WHERE player_id = 1 ORDER BY id DESC LIMIT 2) scores
Any suggestions?
Here the solution:
$sub = playerGame::where('player_id',1)->where('scores','>',0)->limit(2)->orderBy('id','desc');
$count = DB::table( DB::raw("({$sub->toSql()}) as sub") )
->mergeBindings($sub->getQuery())
->sum('scores');
return $count;
Use fromSub():
$sub = playerGame::select('scores')
->where('player_id', 1)
->where('scores', '>', 0)
->limit(2)
->orderBy('id','desc');
$sum = DB::query()->fromSub($sub, 'scores')->sum('scores');
$responce= DB::table('player_games')->where('player_id',1)->sum('amount');
dd(collect($responce)->sortByDesc('id')->take(2));
please cheack this one.....i try it's work....and add use DB;in the top of controller....
SELECT e.match_id, e.team_id
FROM matches
LEFT JOIN match_events e
ON e.match_id = matches.id AND e.match_event_type_id = 1
Try this,
$result = DB::table('matches as M')
->leftjoin('match_events as E','E.match_id','=','M.id')
->where('E.match_event_type_id',1)
->select(['E.match_id','E.team_id'])
->get();
this is my normal mysql command
$query = $this->db->query("SELECT `house_details`.`houses_id` , `house_details`.`house_dis` , `house_details`.`house_type` , `house_details`.`area` , `house_details`.`cost` , `house_details`.`user_id` , `image`.`thumb_path`
FROM (
`house_details`
)
LEFT JOIN `image` ON `image`.`house_id` = `house_details`.`houses_id`
AND `house_details`.`status` =1
GROUP BY `houses_id` DESC
LIMIT $start,$limit ");
return $query->result();
what is the similar code with CI active record class ??
Try this,
$this->db->select('house_details.houses_id, house_details.house_dis, house_details.house_type,house_details.area,house_details.cost,house_details.user_id,image.thumb_path');
$this->db->from('house_details');
$this->db->join('image', 'image.house_id = house_details.houses_id','left');
$this->db->where('image.status', 1);
$this->db->order_by("house_details.houses_id DESC");
$this->db->limit($limit, $start);
$query = $this->db->get();
return $query->result();
Assumed there is no group by since you wanted to order result set in descending order. If group by is there changed it to group_by and remove 'DESC'.
Try this:
$this->db->select('...')->
from('house_details')->
join('image','image.house_id=house_details.houses_id AND image.status=1','LEFT')->
where('...')->
order_by('house_details.houses_id','DESC')->
limit($start,$limit);
