+-- 会员编号字段迁移脚本
+-- 执行日期: 2025-09-26
+-- 描述: 为用户表添加会员编号字段，按照创建时间从1开始递增编号
+
+-- Step 1: 添加会员编号字段
+ALTER TABLE `t_users`
+ADD COLUMN `member_number` INT NULL COMMENT '会员编号（按注册时间递增）' AFTER `gender`;
+
+-- Step 2: 创建索引以提高查询性能
+CREATE INDEX `idx_member_number` ON `t_users` (`member_number`);
+
+-- Step 3: 为现有用户按照创建时间分配会员编号（从1开始递增）
+SET @row_number = 0;
+UPDATE `t_users`
+SET `member_number` = (@row_number := @row_number + 1)
+WHERE `member_number` IS NULL
+ORDER BY `created_at` ASC;
+
+-- Step 4: 验证更新结果
+SELECT
+    COUNT(*) as total_users,
+    MIN(member_number) as min_member_number,
+    MAX(member_number) as max_member_number,
+    COUNT(DISTINCT member_number) as unique_member_numbers
+FROM `t_users`
+WHERE `member_number` IS NOT NULL;
+
+-- Step 5: 显示前10个用户的会员编号分配情况
+SELECT
+    `id`,
+    `name`,
+    `member_number`,
+    `created_at`,
+    `is_guest`
+FROM `t_users`
+WHERE `member_number` IS NOT NULL
+ORDER BY `member_number` ASC
+LIMIT 10;
+
+-- Step 6: 检查是否有重复的会员编号（应该为0）
+SELECT
+    member_number,
+    COUNT(*) as count
+FROM `t_users`
+WHERE `member_number` IS NOT NULL
+GROUP BY `member_number`
+HAVING COUNT(*) > 1;
+
+-- 注意事项:
+-- 1. 此脚本会为所有现有用户分配会员编号，按照创建时间排序
+-- 2. 会员编号从1开始递增
+-- 3. 包含游客用户也会分配编号
+-- 4. 如果只希望为正式用户（非游客）分配编号，请在更新语句中添加条件: WHERE `member_number` IS NULL AND `is_guest` = 0
+-- 5. 执行前请备份数据库
