如何MySQL查詢轉換爲laravel的QueryBuilder

Question

我嘗試我的查詢轉換爲laravel查詢生成器，但我不能獲得成功，我的查詢是mysql如下：

SELECT p.seller, p.purchase_date, p.report_no FROM purchases AS p UNION SELECT ps.seller, ps.purchase_date, ps.report_no FROM purchase_solds AS ps ORDER BY purchase_date DESC 

那麼，如何將它轉換成laravel查詢建設者或laravel雄辯？

Answer 1

你試過

$purchases = DB::table('purchases') 
       ->select('seller', 'purchase_date', 'report_no'); 

$purchase_solds = DB::table('purchase_solds') 
         ->select('seller', 'purchase_date', 'report_no') 
         ->union($purchases) 
         ->orderBy('purchase_date', 'desc') 
         ->get();
