Laravel 原始总和查询到 Laravel 查询构建器

Question

I am trying to create a laravel query builder from the following raw query:

SELECT establishments.*, SUM(invoice_rows.total_price) as total_price_sum 
FROM `establishments` 
JOIN invoices on invoices.establishment_id = establishments.id 
JOIN invoice_rows ON invoice_rows.invoice_id = invoices.id 
WHERE invoice_rows.invoice_article_group_id = 11 
GROUP BY establishments.id 
ORDER BY total_price_sum DESC

I have tried different methods such as: with, whereHas and withCount but I can't seem to create the correct laravel query builder for the raw query.

I think you should take a look at join and Raw in Laravel doc ..

your query should be like this:

   $values=DB::table('establishments')->select(['establishments.id',
            DB::raw('SUM(invoice_rows.total_price) as total_price_sum')])
            ->join('invoices','invoices.establishment_id','=','establishments.id')
            ->join('invoice_rows','invoice_rows.invoice_id','=','invoices.id')
            ->where('invoice_rows.invoice_article_group_id',11)
            ->groupBy('establishments.id')
            ->orderByDesc('total_price_sum')->get();

please note that you cant select establishments.* and then group by only establishments.id
