Question

我想在用户成功预订订单后创建自动奖励系统。在我们的奖励系统中，有15天的订单取消政策。如果取消期间未取消订单，则用户将获得的奖励积分为每order_amount（1000/100）=>每花费100 = 1积分1点

为实现这一点，我在取消期结束且付款状态成功时使用触发器，那么根据上述计算得出的奖励积分将自动插入到user_rewards表中

为此，我为触发器创建了如下代码

之后创建CREATE DEFINER = root @ localhost触发tbl_orders_after_insert

INSERT ON `tbl_orders` FOR EACH ROW BEGIN
    INSERT INTO tbl_rewards
    SET user_id = NEW.user_id,
    order_number = NEW.order_number,
    amount = amount + NEW.payable_amount,
    reward_points = CASE NEW.payment_status WHEN 0 THEN reward_points + (NEW.payable_amount)/100 END;

END
wheere it appends the user_id, order_number but amount and reward_points will always 0 value... Please help me i am stuck on this point

CREATE DEFINER=`root`@`localhost` TRIGGER `tbl_orders_after_insert` AFTER INSERT ON `tbl_orders` FOR EACH ROW BEGIN
    INSERT INTO tbl_rewards
    SET user_id = NEW.user_id,
    order_number = NEW.order_number,
    amount = amount + NEW.payable_amount,
    reward_points = CASE NEW.payment_status WHEN 0 THEN reward_points + (NEW.payable_amount)/100 END;

END

On Updating 

CREATE DEFINER=`root`@`localhost` TRIGGER `after_orders_update` AFTER UPDATE ON `tbl_orders` FOR EACH ROW BEGIN
   UPDATE tbl_rewards
      SET 
         reward_points = (OLD.payable_amount)/100
        WHERE NEW.order_number = OLD.order_number;           
END
My Order Table is 
CREATE TABLE `tbl_orders` (
    `id` INT(11) NOT NULL AUTO_INCREMENT,
    `user_id` INT(11) NOT NULL,

    PRIMARY KEY (`id`)
)
COLLATE='latin1_swedish_ci'

AUTO_INCREMENT=209
;

AND The rewards table is:

CREATE TABLE `tbl_rewards` (
    `id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,
    `user_id` INT(10) NOT NULL,
    `order_number` VARCHAR(10) NOT NULL,
    `reward_points` DOUBLE NOT NULL,
    `amount` DOUBLE NOT NULL,
    `created_at` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
    PRIMARY KEY (`id`)
)
COLLATE='utf8_general_ci'
ENGINE=InnoDB
AUTO_INCREMENT=11
;
