-- ==========================================
-- 学生信息表字段名修复脚本
-- 版本：V2.1.0
-- 功能：修复字段名不匹配问题
-- 作者：Cursor AI 辅助
-- 时间：2025-01-12
-- 问题：数据库字段名与实体类字段名（驼峰转下划线）不匹配
-- ==========================================

-- 设置字符集
SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;

-- ----------------------------
-- 修复 xg_student_info 表字段名
-- ----------------------------

-- 1. 添加缺失的字段
ALTER TABLE `xg_student_info` 
ADD COLUMN `current_address` varchar(200) DEFAULT NULL COMMENT '现住址' AFTER `wechat`,
ADD COLUMN `domicile_place` varchar(100) DEFAULT NULL COMMENT '户籍所在地' AFTER `home_address`,
ADD COLUMN `special_condition` varchar(200) DEFAULT NULL COMMENT '特殊体质或疾病' AFTER `weight`;

-- 2. 重命名字段以匹配实体类
ALTER TABLE `xg_student_info` 
CHANGE COLUMN `emergency_contact` `emergency_contact_name` varchar(50) DEFAULT NULL COMMENT '紧急联系人姓名',
CHANGE COLUMN `emergency_relation` `emergency_contact_relation` varchar(20) DEFAULT NULL COMMENT '紧急联系人关系',
CHANGE COLUMN `emergency_phone` `emergency_contact_phone` varchar(20) DEFAULT NULL COMMENT '紧急联系人电话',
CHANGE COLUMN `father_job` `father_work_unit` varchar(100) DEFAULT NULL COMMENT '父亲工作单位',
CHANGE COLUMN `mother_job` `mother_work_unit` varchar(100) DEFAULT NULL COMMENT '母亲工作单位',
CHANGE COLUMN `is_from_poor_family` `is_poor_student` tinyint(1) DEFAULT 0 COMMENT '是否贫困生：0-否，1-是';

-- 3. 删除不需要的重复字段（如果存在）
-- ALTER TABLE `xg_student_info` DROP COLUMN IF EXISTS `home_zip_code`;
-- ALTER TABLE `xg_student_info` DROP COLUMN IF EXISTS `family_zip_code`;

-- 4. 确保邮政编码字段正确
ALTER TABLE `xg_student_info` 
CHANGE COLUMN `home_zip_code` `postal_code` varchar(10) DEFAULT NULL COMMENT '邮政编码';
