CAKEphp 虚拟字段不工作

Question

因为我的 table 中有两个价格列（subscription_discount 和 subscription_price）。我需要找到一种方法来找到两者中最低的并使用它。问题是只有当 subscription_discount 低于 subscription_price 并且 subscription_discount 不是 0.00 时才会发生这种情况。

这是我在模型中创建虚拟字段的代码：

public $virtualFields = array(
    'end_price' => "IF(Abonnement.subscription_discount IS NOT NULL OR Abonnement.subscription_discount < Abonnement.subscription_price, Abonnement.subscription_price), Abonnement.subscription_discount)"
    );

在我看来，这最终会导致错误：

Error: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '), Abonnement.subscription_discount)) AS Abonnement__end_price FROM `cake' at line 1

我不明白这里出了什么问题。

Answer 1

public $virtualFields = array(
    'end_price' => "IF(Abonnement.subscription_discount IS NOT NULL OR Abonnement.subscription_discount < Abonnement.subscription_price, Abonnement.subscription_price>>>**)**<<<, Abonnement.subscription_discount)"
    );

删除它
