有什么方法可以让行满足 Laravel 中的列之间的关系？

Question

I have a MySQL table named prices which looks like:

Name  | price | amount | total
-------------------------------
name1 |  15   |   2    |  17   
name2 |  20   |   3    |  20
name3 |  25   |   4    |  29
name4 |  30   |   5    |  35

I want to get the names which specify that the sum of the price and amount is equal to the total, which are name1 and name3 in the previous table.

I already did that as SQL query like the following SELECT Name FROM prices WHERE price + amount = total .

Is any way to do it in Laravel Eloquent if I have a prices model?

I don't think eloquent has some magic method for this. But you can always use whereRaw with eloquent as shown below:

Prices::select('name')->whereRaw('price + amount = total')->get();
