如何使長的SQL語句在PHP（或其他語言）中看起來很漂亮？

Question

這是一個例子。 為了看起來舒適，我在其中填充了一些制表符和換行符； 我正在尋找除使用“。”以外的其他更好方法。 鏈接它們。

$str_sql = "SELECT 
          sc.`id` AS 'payment_id',
          sc.`order_id` AS 'order_id',
          od.`partner_id` AS 'partner_id',
          pt.`partner_name` AS 'partner_name',
          od.`term` AS 'order_terms',
          od.`has_pay` AS 'paid_terms',
          sc.`sort_order` AS 'current_term',
          FROM_UNIXTIME(sc.`repayment_time`) AS 'payment_time',
          FROM_UNIXTIME(sc.`receive_time`) AS 'pay_time',
          sc.`order_price` AS 'term_price',
          od.`add_time` AS 'order_time',
          sc.`status` AS 'status',
          od.`order_price` AS 'order_price',
          usr.`user_name` AS 'user_name',
          usr.`id` AS 'user_id',
          usr.`user_cell` AS 'user_cellphone',
          IF(sc.`status` IN (0,3), 1 , 0 ) AS 'overdue',

        FROM 
          mayidev.`lzh_order_payment_schedule` sc 
          JOIN lzh_order od 
            ON sc.`order_id` = od.`id` 
          JOIN lzh_partners pt 
            ON od.`partner_id` = pt.`id` 
          JOIN lzh_order_user usr 
            ON od.id = usr.order_id 
          JOIN lzh_partner_overdue_interest po 
            ON po.`partner_id` = pt.id 
        WHERE sc.`repayment_time` < 1477441800
        AND sc.`receive_time` = 0
          AND sc.`status` != 1
          AND od.`status` = 4 ;";

使長SQL語句在PHP中看起來漂亮的最佳方法是將SQL代碼與PHP代碼分開。 最好的方法是在SQL中創建view和stored procedure以獲取數據。 您實際上並不需要PHP中的所有JOIN邏輯。 最好將其存儲在SQL Server上，以保持代碼的可維護性。

在PHP方面，您只需SELECT * FROM view或CALL procedure() 。
