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

i have this query to return data from two tables based on DISTINCT destination_tbls.destination
like the following:
SELECT DISTINCT
destination_tbls.destination,
MIN(sms_details.id),
MIN(sms_details.msg_timestamp) AS TIMESTAMP,
MIN(destination_tbls.count)
FROM
sms_details
JOIN
(
SELECT
*
FROM
destination_tbls
)
destination_tbls
ON destination_tbls.id = sms_details.destination_tbls_id
GROUP BY
destination_tbls.destination;
Now how to use the paginate with them,
I tried something like this but don't work:
DB::select('
SELECT DISTINCT destination_tbls.destination,MIN(sms_details.id),MIN(sms_details.msg_timestamp) AS TIMESTAMP,MIN(destination_tbls.count)
FROM sms_details
JOIN(SELECT * FROM destination_tbls) destination_tbls ON destination_tbls.id=sms_details.destination_tbls_id
GROUP BY destination_tbls.destination
')->simplePaginate(100);
Any help would be appreciated!
If you want to use laravel's pagination, you need to write the query using the query builder methods.
$results = DB::table('sms_details')
->select('destination_tbls.destination')
->selectRaw('min(sms_details.id)')
->selectRaw('min(sms_details.msg_timestamp) as timestamp')
->selectRaw('min(destination_tbls.count)')
->distinct()
->joinSub(
function ($sub) {
$sub->from('destination_tbls');
},
'destination_tbls',
function ($join) {
$join->on('destination_tbls.id', '=', 'sms_details.destination_tbls_id');
}
)
->groupBy('destination_tbls.destination')
->simplePaginate(100);
Since you're not really doing anything in the subquery join, you could join the table instead.
$query = DB::table('sms_details')
->select('destination_tbls.destination')
->selectRaw('min(sms_details.id)')
->selectRaw('min(sms_details.msg_timestamp) as timestamp')
->selectRaw('min(destination_tbls.count)')
->distinct()
->join('destination_tbls', 'destination_tbls.id', '=', 'sms_details.destination_tbls_id')
->groupBy('destination_tbls.destination')
->simplePaginate(100);
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 am using LARAVEL 4 with MySQL back-end. I am novice to it.
I have a statement that returns records from 3 different tables as below :
$templates = Template::with('children')
->leftJoin('template_masters', function($join) {
$join->on('templates.template_master_id', '=', 'template_masters.id');
})
->leftJoin('surveyes', function($join) {
$join->on('templates.survey_id', '=', 'surveyes.id');
})
->get([
'templates.id',
'templates.survey_id',
'surveyes.title', // Here I want the IFNULL() condition e.g. IFNULL('surveyes.title','templates.title')
'templates.type',
'templates.created_at',
'template_masters.is_default'
]);
Basically this creates a query something like :
select `templates`.`id`,
`templates`.`survey_id`,
`surveyes`.`title`,
`templates`.`type`,
`templates`.`created_at`,
`template_masters`.`is_default`
from `templates`
left join `surveyes` on `templates`.`survey_id` = `surveyes`.`id`
left join `template_masters` on `templates`.`template_master_id` = `template_masters`.`id`
But I want this query like :
select `templates`.`id`,
`templates`.`survey_id`,
IFNULL(`surveyes`.`title`, `templates`.`title`),
`templates`.`type`,
`templates`.`created_at`,
`template_masters`.`is_default`
from `templates`
left join `surveyes` on `templates`.`survey_id` = `surveyes`.`id`
left join `template_masters` on `templates`.`template_master_id` = `template_masters`.`id`
In short, instead of surveyes.title, I want IFNULL(surveyes.title,templates.title).
How can I achieve this in ->GET([]) statement of given Eloquent ORM?
Thanks.
You need to use raw statement:
...
->get([
'templates.id',
'templates.survey_id',
DB::raw('IFNULL(surveyes.title,template_masters.title) as title'),
// or if you use namespace:
\DB::raw('IFNULL(surveyes.title,template_masters.title) as title'),
'templates.type',
'templates.created_at',
'template_masters.is_default'
]);
Can I write something like this:
$post = Post::join(['author'])->find($postId);
$authorName = $post->author->name;
To produce only ONE select with inner join (no 2 selects) and without using DB query builder
SELECT
post.*,
author.*
FROM post
INNER JOIN author
ON author.id = post.author_id
WHERE post.id = ?
You can do it in Eloquent using the join method:
$post = Post::join('author', function($join)
{
$join->on('author.id', '=', 'post.author_id');
})
->where('post.id', '=', $postId)
->select('post.*', 'author.*')
->first();
Please note that your results in $post will be an object where their attributes will correspond to the result set, if two columns has the same name it will be merged. This happen when using:
->select('post.*', 'author.*')
To avoid this, you should create alias to those columns in the select clause as shown below:
->select('post.id AS post_id', 'author.id AS author_id')
Try
Post::join('author',function($join){
$join->on('author.id','=','post.author_id');
})->where('post.id','=',$postId)->select('post.*','author.*');
