如何MySQL查询转换为laravel的QueryBuilder

Question

我尝试我的查询转换为laravel查询生成器，但我不能获得成功，我的查询是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 

那么，如何将它转换成laravel查询建设者或laravel雄辩？

Answer 1

你试过

$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();
