Laravel 原始總和查詢到 Laravel 查詢構建器

Question

我正在嘗試從以下原始查詢創建 Laravel 查詢構建器：

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

我嘗試了不同的方法，例如：with、whereHas 和 withCount，但我似乎無法為原始查詢創建正確的 Laravel 查詢構建器。

我認為你應該看看 Laravel 文檔中的join和Raw ..

你的查詢應該是這樣的：

   $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();

請注意，您不能選擇establishments.*然后僅按establishments.id id 分組
