-- 使用数据库
USE peixue;

-- 第一步：创建评价表
-- =====================================================
DROP TABLE IF EXISTS `review`;

-- =====================================================
-- 第二步：为order表添加reviewed字段
-- =====================================================

-- 检查字段是否存在
SET @col_exists = 0;
SELECT COUNT(*) INTO @col_exists 
FROM information_schema.COLUMNS 
WHERE TABLE_SCHEMA = 'peixue' 
  AND TABLE_NAME = 'order' 
  AND COLUMN_NAME = 'reviewed';

-- 如果字段不存在，则添加
SET @sql = IF(@col_exists = 0,
  'ALTER TABLE `order` ADD COLUMN `reviewed` TINYINT(1) NOT NULL DEFAULT 0 COMMENT ''是否已评价（0-未评价，1-已评价）'' AFTER `status`',
  'SELECT ''字段 reviewed 已存在，跳过添加'' AS message'
);

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

-- =====================================================
-- 第三步：插入测试数据
-- =====================================================

-- 插入测试数据（明确指定所有字段）
INSERT INTO `review` (
  `order_id`, 
  `user_id`, 
  `teacher_id`, 
  `student_id`,
  `service_score`, 
  `quality_score`,

  `overall_score`,
  `content`, 
  `images`, 
  `is_anonymous`, 
  `tenant_id`

-- =====================================================
-- 第四步：更新订单的评价状态
-- =====================================================
UPDATE `order` SET `reviewed` = 1 WHERE `id` IN (102, 103, 104);

-- =====================================================
-- 第五步：验证数据
