-- ===========================================
|
||||
-- 班级操行分管理系统 - v2.0 数据库迁移脚本
|
||||
-- 适用版本: v1.8 → v2.0
|
||||
-- 字符集: utf8mb4
|
||||
--
|
||||
-- 说明:
|
||||
-- v2.0 主要为应用层代码变更（UI折叠菜单、扣分类型扩展、
|
||||
-- 科目选择修复、页面改名、记录人优化、学期管理优化等），
|
||||
-- 数据库 schema 变更较少。本脚本主要处理历史数据迁移
|
||||
-- 和索引优化。
|
||||
--
|
||||
-- 迁移内容:
|
||||
-- 1. 将 conduct_records.recorder_name 从用户名更新为真实姓名
|
||||
-- 2. 将 attendance_records 相关记录中的 recorder_name 同步更新
|
||||
-- 3. 确保 semester_id 索引存在（学期记录数统计优化）
|
||||
-- 4. 数据验证
|
||||
--
|
||||
-- 重要: 执行前请备份数据库！
|
||||
-- ===========================================
|
||||
|
||||
USE `classmanagerdb`;
|
||||
|
||||
-- ===========================================
|
||||
-- 1. 更新 conduct_records 中的 recorder_name
|
||||
-- v2.0 将 recorder_name 从用户名(username)改为真实姓名(real_name)
|
||||
-- 需要将历史记录中的用户名更新为对应的真实姓名
|
||||
-- ===========================================
|
||||
|
||||
-- 通过 JOIN users 表将 recorder_name 从 username 更新为 real_name
|
||||
