I try to do a query on a view from DB, with Laravel but I get an error, and I am not sure why.
ViewData::query()->where('page', '=', '918');
"SQLSTATE[42601]: Syntax error: 7 ERROR: zero-length delimited
identifier at or near """"↵LINE 1: ...data" where "page" = $1 order by
"view_full_data"."" asc lim...↵
^ (SQL: select * from "view_full_data" where "page" = 918 order by
"view_full_data"."" asc limit 1000 offset 0)"
From Postgres, a working one.
Select * from view_full_data where "page = 918;
I found the problem.
From Maatwebsite\Excel I get an order_by that is not ok (Maybe because I don't have an ID column).
I had to add orderBy manually.
ViewData::query()->where("page", '=', "918")->orderBy('page', 'asc');

I'm trying to group data by month for the current year. The query below works on MySQL database but gives an error when connected to PostgreSQL.
$results = DB::table('visits')
->select(DB::raw('month(visitdate) month, count(*) data'))
->where('team_id', 2)
->whereYear('visitdate', now()->year)
->groupBy('month')
->get();
This error was generated:
SQLSTATE[42601]: Syntax error: 7 ERROR: syntax error at or near "month" LINE 1: select month(visitdate) month, count() data from "visits" w... ^ (SQL: select month(visitdate) month, count() data from "visits" where "team_id" = 2 and extract(year from "visitdate") = 2021 group by "month")
I tried a similar query with Eloquent and got the same results.
The visitdate column stores the date in the format "2021-01-01"
I'm using laravel 8 with Breeze
month is a keyword. You should choose something else instead, or put it in double quotes, or in this case just put AS in front of it. Any of the three should work.
Suppose I have two tables: posts and tags. I want to eager load all the tags with posts whose post count is larger than 10. How would I do it?
I tried the following but not work:
Tag::withCount('posts')
->where('posts_count', '>' , 10)
->get();
It gives me the following error:
Column not found: 1054 Unknown column 'posts_count' in 'where clause' (SQL: select `tags`.*, (select count(*) from `posts` inner join `post_tag` on `posts`.`id` = `post_tag`.`post_id` where `tags`.`id` = `post_tag`.`tag_id`) as `posts_count` from `tags` where `posts_count` > 1 order by `posts_count` desc)
try this:
Tag::withCount('posts')->having('posts_count', '>' , 10)->get();
If you want to filter on aggregates, you need to use having.
i have this raw query and i want to use it in eloquent query builder
but seems i cant use date method in eloquent and gave me this error im new in eloquent. what is the problem:
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'date(prizes.created_at), user_id' in 'group statement' (SQL: select user_id,COUNT(user_id), date(created_at) from `prizes` group by `date(prizes`.`created_at), user_id` having `user_id` = 1 order by `date(created_at)` desc)
raw SQL:
SELECT
user_id,COUNT(user_id), DATE(created_at) FROM prizes
GROUP BY DATE(prizes.created_at), user_id
HAVING user_id = 1
ORDER BY DATE(created_at) DESC
limit 2
Eloquent:
$points = \App\Prize::selectRaw('user_id,COUNT(user_id), date(created_at)')
->groupBy("date(prizes.created_at), user_id")
->orderBy("date(created_at)","DESC")
->having("user_id","=",1)
->get();
what is the the cleanest and best form??
By default, Laravel tries to parse all strings as tables. This means it will add the string between `.
To avoid this, you can put the string in a DB:raw() function to let Laravel know not to parse this string and send it as-is to the database.
->orderBy(\DB::raw("date(created_at)"), "DESC")
Or use the raw method for ordering:
->orderByRaw('date(created_at) desc')
The goal is to sort my campaigns by views in my filtration, which is why i have an analytics table with relations to my campaigns
My campaign model (The DB name is "ads"):
public function views() {
return $this->hasMany('App\Analytic', 'foreign_id', 'id')->where('foreign_type', '=', 'campaign');
}
The controller of my filtration:
$query = Ad::withCount('views')->with('tags');
$query->where("is_active", "=", 1);
$query->where("status", "=", 1);
$query->orderBy('views_count', 'DESC');
$campaigns = $query->get();
Now the reason for not writing it without the $query-> part, is because the query has lots of if statements depending on filtration settings.
The error im getting:
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'views_count' in 'order clause' (SQL: select count(*) as aggregate from `ads` where `is_active` = 1 and `status` = 1 and `from_year` >= 7 and `to_year` <= 88 and `price` >= 1000 and `price` <= 64000 order by `views_count` desc)
The error is it tries to fetch a column, but i can't figuere out why.
If i try to access $campaign->views_count in my blade template, it shows the count just fine.
Thank you for your time, i hope someone can tell me what I'm doing wrong here.
The error you're getting is a result of a count() method not a get().
something like this
$query = Ad::withCount('views')->with('tags');
$query->where("is_active", "=", 1);
$query->where("status", "=", 1);
$query->orderBy('views_count', 'DESC');
$campaignCount = $query->count();
wich replaces the complex select part with:
select count(*) as aggregate
if you need the count() and the get(), do it like this:
$query = Ad::withCount('views')->with('tags');
$query->where("is_active", "=", 1);
$query->where("status", "=", 1);
$campaignCount = $query->count();
$query->orderBy('views_count', 'DESC');
$campaigns = $query->get();
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();
