I'm very new to Laravel, how can I make this query in Laravel using Eloquent model:
SELECT
(
SELECT departments.deptname FROM school.counts
LEFT JOIN reference.departments
ON counts.departmentcode = department.departmentcode
WHERE counts.countid = a.countsid
) AS departmentDesc
FROM school.subjecthdr a
LEFT JOIN school.subjectdtls b
ON a.subjectid = b.subjectid;
I don't wish to use raw queries, is there any way? I still appreciate raw query suggestions if there's any.
I think you still need some raw queries.
$dept_desc = \DB::table('school.counts')
->leftjoin('reference.departments', 'counts.departmentcode', '=', 'departments.departmentcode')
->whereRaw('counts.countid = a.countsid')
->selectRaw('departments.deptname');
\DB::table('school.subjecthdr AS a')
->leftjoin('subjectdtls AS b', 'a.subjectid', '=', 'b.subjectid')
->selectRaw('(' . $dept_desc->toSql() . ') AS departmentDesc')
->get();
PS: I think you leftjoin subjectdtls b but it seems you don't need it.
And you are using not only one database, if you want to use Eloquent\Builder,
you need to do something like this:

This SQL:
SELECT COUNT(*) AS total_see_all_video
from users u
WHERE 7 = (SELECT COUNT(*) FROM lecciones_users lu WHERE lu.uuid = u.uuid)
I tried this code but did not work:
$data = LeccionesUsers::select(
DB::raw('COUNT(*) AS total_ase_vis_videos'),
DB::raw('where 7 = (SELECT COUNT(*) FROM lecciones_users where leccion_users.uuid = users.uuid)')
)
->join('users', 'lecciones_users.uuid', '=', 'users.uuid')
->get();
Your issue is that you are not correctly forming your query. You can do ->toSql(); instead of ->get(); and you would see the final SQL (would definitely not be the same as the one you wrote first).
So, you should have this to have the same SQL:
$total_see_all_video = LeccionesUsers::whereRaw('7 = (SELECT COUNT(*) FROM lecciones_users where leccion_users.uuid = users.uuid)')
->count();
Please, try my query (and also run ->toSql() to see if you have a correct SQL).
I would still recommend to use relationships and it is very weird to do 7 = query.
You can use
DB::query()->fromSub('Raw sql query here..')
and then can perform actions on this.For the reference you can use the documentation fromSub
You can also look into this convert this where break this query to parts to be used accordingly. You can use this section for the reference purpose:

Hope this will help you with the result.
SELECT lamparas.id,lampara, contenedor_id, contenedor, encendido_apagado, lamparas.estado
FROM lamparas
INNER JOIN contenedores ON lamparas.contenedor_id = contenedores.id
Assuming you are using Laravel 8 and Eloquent you could try something like:
$results = DB::table('lamparas')
->join('contenedores', 'lamparas.contenedor_id', '=', 'contenedores.id')
->select('lamparas.id', 'lampara', 'contenedor_id', 'contenedor', 'encendido_apagado', 'lamparas.estado')
->get();
You should really have a read of the docs: https://laravel.com/docs/8.x/queries
SELECT `foduu_listing`.`id`,`foduu_listing_filedetail`.`primary`, `foduu_listing`.`name`,`foduu_listing`.`filemanager_id`,`foduu_filemanager`.`filepath`,`foduu_detail_orders`.`listing_id`, COUNT(`foduu_detail_orders`.`listing_id`) AS count,SUM(`foduu_detail_orders`.`total`) AS total
FROM foduu_listing
left join `foduu_detail_orders` on `foduu_listing`.`id` = `foduu_detail_orders`.`listing_id`
left join `foduu_listing_filedetail` on `foduu_listing`.`id` = `foduu_listing_filedetail`.`listing_id`
left join `foduu_filemanager` on `foduu_listing`.`filemanager_id` = `foduu_filemanager`.`id`
where `foduu_detail_orders`.`listing_id` = 593
I would do it like this:
DB::table('foduu_listing')->select('foduu_listing.id`,foduu_listing_filedetail.primary, foduu_listing.name,foduu_listing.filemanager_id,foduu_filemanager.filepath,foduu_detail_orders.listing_id')
->leftJoin('foduu_detail_orders', 'foduu_listing.id', '=', 'foduu_detail_orders.listing_id')
->leftJoin('foduu_listing_filedetail', 'foduu_listing.id', '=', 'foduu_listing_filedetail.listing_id')
->leftJoin('foduu_filemanager', 'foduu_listing.filemanager_id', '=', 'foduu_filemanager.id')
->selectRaw('COUNT(`foduu_detail_orders`.`listing_id`) AS count')
->selectRaw('SUM(`foduu_detail_orders`.`total`) AS total')
->where('foduu_detail_orders.listing_id', 593)
->get();
If instead of calling get at the end you call toSql you can check the query generated:
select `foduu_listing`.`id``,foduu_listing_filedetail`.`primary, foduu_listing`.`name,foduu_listing`.`filemanager_id,foduu_filemanager`.`filepath,foduu_detail_orders`.`listing_id`, COUNT(`foduu_detail_orders`.`listing_id`) AS count, SUM(`foduu_detail_orders`.`total`) AS total from `foduu_listing` left join `foduu_detail_orders` on `foduu_listing`.`id` = `foduu_detail_orders`.`listing_id` left join `foduu_listing_filedetail` on `foduu_listing`.`id` = `foduu_listing_filedetail`.`listing_id` left join `foduu_filemanager` on `foduu_listing`.`filemanager_id` = `foduu_filemanager`.`id` where `foduu_detail_orders`.`listing_id` = ?
However you are not making use of Laravel tools if you just translate your queries from raw SQL to Eloquent like this, you should define your models and your relationships properly and then make use of that for querying your data.
I'm currently trying to use the Eloquent query builder to create a join with multiple clauses, one of which being an IN clause.
The type of query I would like to create would be
SELECT * FROM trusts t
LEFT JOIN trust_group tg ON tg.trust_id = t.id
AND tg.group_id IN (1,2,4)
I've tried
->leftJoin('trust_group', function($join) {
$join->on('trust_group.trust_id', '=', 'trusts.id');
$join->on('trust_group.group_id', 'IN', [1,2,4]);
})
which results in
and `trust_group`.`group_id` = `IN`
and I've also tried
->leftJoin('trust_group', function($join) {
$join->on('trust_group.trust_id', '=', 'trusts.id');
$join->on(DB::raw('trust_group.group_id IN (1,2,4)'));
})
but this results in a query containing something along the lines of
and trust_group.group_id IN (1,2,4) = ``
(Obviously those group IDs are for example purposes, and would by dynamic)
Can Eloquent support IN clauses on joins?
This is only part of a pretty large query, so would prefer to use the join rather than use a whereIn
As this is kinda deadlock at the moment, I am posting this as an answer until this is officially PRed. Unfortunately joining with an In clause is not yet supported officially. There are some discussions in this closed thread
You can use it as raw query :
<?php
$results = DB::select("
SELECT * FROM trusts t
LEFT JOIN trust_group tg ON tg.trust_id = t.id
AND tg.group_id IN (?)", $groupIds);
Also there is Model::hydrate($array) method if you want to have eloquent collection back from result array.
This is a pretty old post, but for anyone searching, you can now simply use where functions to build more complex joins (tested in Laravel 7) :
->leftJoin('trust_group', function($join) {
$join
->on('trust_group.trust_id', '=', 'trusts.id')
->whereIn('trust_group.group_id', [1, 2, 4])
;
})
I have the following query:
select i.name,i.id itemId,its.item_id from items i
LEFT JOIN items_subscribers its
ON i.id = its.item_id
and its.user_id = 1
Which I transformed into Eloquent Way like this:
$records = Item::where('items_subscribers.user_id',$user_id)
->leftJoin('items_subscribers','items.id','=','items_subscribers.item_id')
->select(['items.name','items.id','items_subscribers.item_id as selected_item_id'])->get();
When I run print_r(DB::getQueryLog()); it prints following query:
select `items`.`name`, `items`.`id`, `items_subscribers`.`item_id` as `selected_item_id` from `items` left join `items_subscribers` on `items`.`id` = `items_subscribers`.`item_id` where `items_subscribers`.`user_id` = ?
The query yields nothing. I want to use AND instead of WHERE. How'd I do this?
I am using Laravel 4.2
Try using a closure and adding the condition in there:
$records = Item::leftJoin('item_subscribers', function($join) use ($user_id){
$join->on('items.id','=','items_subscribers.item_id');
$join->where('items_subscribers.user_id', '=', $user_id);
})
->select(['items.name','items.id','items_subscribers.item_id as selected_item_id'])
->get();
Just add another on method at the leftJoin part instead of using the where method. - https://stackoverflow.com/a/26714765/3208719
