Laravel Eloquent duplicate distinct row

问题

Let's consider the image above. I would like to show duplicated entries as one entry and also I want to show the sum of the "stock" column. In this case it should be 5722.

Is it possible to do it using Eloquent? Or what are the best ways to do it?

回答1:

Not sure how your database / query is built but you could maybe use something like that:

Item::groupBy('item_name')
   ->selectRaw('*, sum(stock) as sum')
   ->get();

It will return a collection of Item with an additional “sum” field

回答2:

This will group the result with same medicine and supplier name and sum up the stock.

$result = Model_Name::groupBy('medicine_name','supplier_name')
                         ->selectRaw('*, sum(stock) as sum')
                         ->get();

Try this. Hope it might help you.
