I need to get total count to show in my page.
I can run this & loop through & get the total number
DB::table('table1')
->select((DB::raw('MAX(score)')))
->where('status', 1)
->groupBy('user_id')
->get();
But this query would give me the count in just a single query & I don't need run any extra loop to get the total.
SELECT COUNT( * ) FROM (
SELECT MAX( score ) FROM table1
WHERE status =1
GROUP BY user_id
) AS totalCounter
How am I suppose to run this RAW query in Laravel 4?
Try
DB::statement( 'Your Query' );
or
DB::select( 'Your Query' );
As mentioned by other contributors;-
DB::select('SQL QUERY GOES HERE WITH PARAMETERS ?, ?', array('parameter 1', 'parameter 2'));
The code above should permit raw sql.
However,
DB::table('table1')
->select((DB::raw('MAX(score)')))
->where('status','=', 1)
->groupBy('user_id')
->count();
Should achieve the same effect for the task you seek it for, and is more in tune with laravels philosophy.
DB::select(DB::raw("SQL QUERY CODE HERE"))
Both raw and select are require!
Please see for more info:
Laravel 4: how to run a raw SQL?
Try this
DB::select( DB::raw("SELECT * FROM table_Name WHERE col = :somevariable"), array(
'somevariable' => $someVariable,
));

I'm using Laravel 7. I have a table named assistances witch has some columns and those two columns:
- start_date
- end_date
I'd like to sort data order by the duration between start_date and end_date:
$query = Assistance::join('users', 'assistances.user_id', '=', 'users.id')
->select('assistances.*')
->orderBy('duration between start_date and end_date');
;
How can I do this ?
Please try the following - bare in mind that this is not hugely efficient
DATEDIFF returns the days between two dates. You may also want to use TIMESTAMPDIFF which accepts a first parameter such as 'hour' where you can get more granular control
$query = Assistance::join('users', 'assistances.user_id', '=', 'users.id')
->select('assistances.*')
->orderBy(DB::raw('DATEDIFF(start_date, end_date)'))
->get();
Please also use DB; in your class.
In Laravel 6.18 I'm trying to figure out how to recreate the following Postgres query.
with data as (
select date_trunc('month', purchase_date) as x_month, date_trunc('year', purchase_date) AS x_year,
sum (retail_value) AS "retail_value_sum"
from coins
where user_email = 'user#email.com' and sold = 0
group by x_month, x_year
order by x_month asc, x_year asc
)
select x_month, x_year, sum (retail_value_sum) over (order by x_month asc, x_year asc rows between unbounded preceding and current row)
from data
I know how to build the main part of the query
$value_of_all_purchases_not_sold = DB::table('coins')
->select(DB::raw('date_trunc(\'month\', purchase_date) AS x_month, date_trunc(\'year\', purchase_date) AS x_year, sum(retail_value) as purchase_price_sum'))
->where('user_email', '=', auth()->user()->email)
->where('sold', '=', 0)
->groupBy('x_month', 'x_year')
->orderBy('x_month', 'asc')
->orderBy('x_year', 'asc')
->get();
but how do you build out the with data as ( and the second select?
I need the data to be cumulative and I'd rather do the calculation in the DB than in PHP.
Laravel doesn't have built-in method(s) for common table expression. You may use a third party package such as this - it has a very good documentation. If you don't want to use an external library, then you need use query builder's select method with bindings such as
$results = DB::select('your-query', ['your', 'bindings']);
return Coin::hydrate($results); // if you want them as collection of Coin instance.
My working SQL query is as follows:
SELECT post_id
FROM news_tags
ORDER BY (link_clicks+views) DESC
What I've tried so far in eloquent is like this:
$newsTagSaved = NewsTag::
orderBy(DB::raw("`views` + `link_clicks`"), 'desc')
->paginate(12)
->pluck('post_id');
Newstag table has many columns and views and link_clicks are two of them. Now, I'm trying to retrieve the post_id order by desc of sum of views and link_click.
How can I do it in Laravel eloquent?
Thank you!
Do something like this:
$newsTagSaved = NewsTag::select(DB::raw('views + link_clicks as score'))
->orderBy('score', 'desc')
->get();
dd($newsTagSaved);
This will return just score value. If you want to return other fields, simply add them to select. As an example:
$newsTagSaved = NewsTag::select(
DB::raw('views + link_clicks as score'),
'title',
'created_at'
)
->orderBy('score', 'desc')
->get();
dd($newsTagSaved);
I've been working on a few tables where through a rather complex relationship (that I'm trying to clean up, but I still need reports made from the data through my Laravel).
At the moment, I can pull the data using the following SQL query to my MySQL database:
SELECT
customers.id,
customers.customer_name,
SUM(shipments.balance) AS shipmentBalance
FROM customers
LEFT JOIN shipments
ON customers.id = shipments.bill_to
AND balance > (SELECT IFNULL(SUM(payments_distributions.amount),0)
FROM payments_distributions
WHERE payments_distributions.shipment_id = pro_number)
GROUP BY customers.id, customers.customer_name
ORDER BY shipmentBalance DESC
LIMIT 5;
I'm just not sure how to rewrite it properly into the whereRaw or DB::raw statements that Laravel Eloquent requires, as my previous attempts have failed.
Update
Here is the closest solution I have tried:
DB::table('customers')
->select('customers', DB::raw('SUM(shipments.balance) AS shipmentBalance'))
->leftJoin(
DB::raw('
(select shipments
ON customers.id = shipments.bill_to
AND balance > (SELECT IFNULL(SUM(payments_distributions.amount),0)
FROM payments_distributions
WHERE payments_distributions.shipment_id = pro_number)'))
->groupBy('customers.id')
->orderByRaw('shipmentBalance DESC')
->limit(5)
->get();
Update 2
Edit for Dom:
Using everything as it stands with your answer, I get the following response:
SQLSTATE[42S22]: Column not found: 1054 Unknown column '' in 'on clause' (SQL: select customers.id, customers.customer_name,SUM(s.balance) AS shipmentBalance from `customers` left join `shipments` as `s` on `customers`.`id` = `s`.`bill_to` and s.balance > (SELECT IFNULL(SUM(payments_distributions.amount),0) FROM payments_distributions WHERE payments_distributions.shipment_id = s.pro_number) = `` group by `customers`.`id`, `customers`.`customer_name` order by SUM(s.balance) DESC limit 5)
But if I remove this section, it brings up the page and the customers (though in the wrong order as I have removed one of the necessary components:
$join->on(DB::raw('s.balance >
(SELECT IFNULL(SUM(payments_distributions.amount),0)
FROM payments_distributions
WHERE payments_distributions.shipment_id = s.pro_number)
'));
Is there anything I can provide you with to get this specific statement to work with your entire answer?
Use this:
DB::table('customers')
->select('customers.id', 'customers.customer_name', DB::raw('SUM(shipments.balance) AS shipmentBalance'))
->leftJoin('shipments', function($join) {
$join->on('customers.id', 'shipments.bill_to')
->where('balance', '>', function($query) {
$query->selectRaw('IFNULL(SUM(payments_distributions.amount),0)')
->from('payments_distributions')
->where('payments_distributions.shipment_id', DB::raw('pro_number'));
});
})
->groupBy('customers.id', 'customers.customer_name')
->orderByDesc('shipmentBalance')
->limit(5)
->get();
Without the Models containing relationships or being able to test on this specific project, this is the most eloquent way I can think of performing your task.
The benefit of starting with the Customer model is you will have a laravel collection and can paginate as needed. Also review the eloquent docs, they help you understand all the different options. Hope his helps.
P.S. Start by using your model in your controller or wherever you are placing this query with:
use App\Customer
The query
$theQuery = Customer::select(DB::raw('customers.id, customers.customer_name,SUM(s.balance) AS shipmentBalance'))
->leftJoin('shipments as s', function($join)
{
$join->on('customers.id', '=', 's.bill_to');
$join->on(DB::raw('s.balance >
(SELECT IFNULL(SUM(payments_distributions.amount),0)
FROM payments_distributions
WHERE payments_distributions.shipment_id = s.pro_number)
'));
})
->groupBy('customers.id', 'customers.customer_name')
->orderByRaw('SUM(s.balance) DESC')
->limit(5)
->get();
I have the following MySQL query which fetches a list of the last 9 authors to write a post and lists them in order of the date of the last post they wrote.
It's working properly but I'd like to re-write it using the Laravel Query Builder. Here is the query at the moment:
$authors = DB::select("
SELECT
`a`.`id`,
`a`.`name`,
`a`.`avatar`,
`a`.`slug` AS `author_slug`,
`p`.`subheading`,
`p`.`title`,
`p`.`slug` AS `post_slug`,
`p`.`summary`,
`p`.`published_at`
FROM
`authors` AS `a`
JOIN
`posts` AS `p`
ON `p`.`id` =
(
SELECT `p2`.`id`
FROM `posts` AS `p2`
WHERE `p2`.`author_id` = `a`.`id`
ORDER BY `p2`.`published_at` DESC
LIMIT 1
)
WHERE
`a`.`online` = 1
ORDER BY
`published_at` DESC
LIMIT 9
");
I understand the basics of using the query builder, but there doesn't appear to be anything in the Laravel docs that allows for me to JOIN a table ON a SELECT.
Can anyone suggest a way that I can write this query using the Laravel Query builder, or perhaps suggest a way that I can rewrite this query to make it easier to structure with the query builder?
Try to do like this
$data = DB::table('authors')
->select(
'a.id',
'a.name',
'a.avatar',
'a.slug AS author_slug',
'p.subheading',
'p.title',
'p.slug AS post_slug',
'p.summary',
p.published_at')
->from('authors AS a')
->join('posts AS p', 'p.id', '=', DB::raw("
(
SELECT p2.id FROM posts AS p2
WHERE p2.author_id = b.id
ORDER BY p2.published_at
DESC LIMIT 1
)"))
->where('a.online', 1)
->limit(9)
->orderBy('p.published_at', 'desc')
->get();
