如何将 mysql 查询转换为 laravel querybuilder

Question

我尝试将我的查询转换为 laravel 查询生成器，但我无法成功，我的查询在 mysql 中，如下所示：

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

那么如何将其转换为 laravel 查询生成器或 laravel eloquent？

Answer 1

你试过了吗

$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();
