I am a student and is new to MySQL
I have 2 tables, ors_uniform contains 7 products that has 9 sizes (XS-5XL).
ors_prices contains the fk of table1 and the prices per size (9 sizes)
I wanted it so that when I output the inventory of the products, the price will be shown next to it. I know how to do that using php already but I don't know what MySQL query to use.
I currently just use SELECT * FROM ors_uniform
2 tables
let's assume the fk is a foreign key and it is available in both tables.
select * from ors_uniform join ors_prices on ors_uniform.fk = ors_prices.fk;

I have a courses table and every course has many sessions,
So I need to sort courses by the first session of the course date for Laravel Project.
this way you can set a method in Course model to get the oldest Session model(which means first session):
public function oldestSession()
{
return $this->hasOne(Session::class)->oldestOfMany();
}
and then you may simply query your course model by adding constraints on that method :
$courses = Course::with(['oldestSession' => function ($query) {
$query->orderBy('created_at', 'desc');
}])->get();

i have a table called sales, there are 100 rows, table has 2 fields, namely total and commission, i want to get SUM(total-commission) of all rows into a single value
You can user Eloquent Builder sum() function.
$sum = Sale::select(
DB::raw('commissioned_total as total - commission')
)
->sum('commissioned_total');
Or you can user Laravel Collection sum() function.
$sum = Sale::all()->sum(function($sale) {
return $sale->total - $sale->commission;
});
You can enhance this method more,
Define this commissionedTotal() function on Sale model, and use sum function as Higher Order Message.
Sale Model
public function commissionedTotal()
{
return $this->total - $this->commission;
}
Controller
$sum = Sale::all()->sum->commissionedTotal()
This third approach is more elegant and It's the Laravel preferred way.
As per you state in question there only two fileds a sample query may be:
SELECT SUM(s.total-s.commission) as myResult from sales as s WITH (NOLOCK);

First of all I wish you a new happy year! So I have 3 articles for example and each of them has an order, like 1,2,3. If I want to delete the last article for example, the order of the other articles still remain the same 1,2. But if I delete the first article the orders of the others should decrease with 1 and if I delete the middle one only the order of the last article should decrease.
Now how to do this in php? I refer to delete in database
Any idea is appreciated.
I don't have any code yet because I wanted to find first a solution, I only give the id of the article, the order and the category from which it belongs:
if($_POST['actiune'] == 'updateArticle'){
$id_article = $_GET['id'];
$ord = $_GET['order'];
$categ = $_GET['categ'];
}
You could do an update after each delete. Something like:
UPDATE [ArticleTable] SET [OrderColumn]=[OrderColumn]-1 WHERE [OrderColumn]>=[ORDERVALUE_FROM_DELETED_ITEM]

I have a table in database that is TEXT field. In this table i have stored my product ids . Now when i go to cart and get all product id of cart i want to match from database field and get only those ids that there stored in product id.
Please see image first.
In this field you will see "check_values" field. here all product ids are stored in comma separated.
Let me take a example
Like i have purchase a product that product id is 161. So i want to match 161 id from "check_value" filed and get only those ids (from images) that having 161.(11,14,15).
Hope you understand my question.
You can use FIND_IN_SET e.g.
SELECT * FROM images WHERE FIND_IN_SET(161, check_values) > 0
