+更新 sys_dept 表：
+1) 打印 sys_dept 表结构供学习
+2) 可删除 sys_dept 中除 dept_id 为 100/101/102 外的所有记录（需确认或使用 --yes）
+3) 从 teacher.xlsx 中读取部门列，按规则插入到 sys_dept （部分学院放到 parent_id=101，其余放到 102）

+目的:
+  在 sys_dept 表中，对于同一学院(parent_id)下的相同专业名称(dept_name)只保留一条记录，删除重复记录。
+
+行为:
+  - 默认 dry-run：打印将要执行的 SQL 操作，不做修改。
+  - 传入 --apply 会执行修改（在事务中）。
+  - 对于重复记录，会保留 dept_id 最小的那条作为主记录（keep_id），
+    并将重复记录的子部门(parent_id 指向被删除 id) 统一改为 keep_id，
+    同时将 sys_user 表中引用的 dept_id 更新为 keep_id。
+  - 会打印处理摘要。
+
+使用:
+  python3 04-01-dedupe_sys_dept.py --host ... --user ... --password ... --database ... [--apply]
+
+注意:
+  在运行前请先备份数据库。对非数字或特殊 dept_name 不做额外过滤，脚本基于 parent_id + dept_name 进行分组。

+04 - 专业信息入库脚本

+说明:
+- 从 `his_xssj` 表读取学院编号、专业编号、专业名称（去重）
+- 根据学院编号映射到学院名称，然后在 `sys_dept`（或目标表）中查找父节点 parent_id
+- 若专业在目标表中不存在，则生成 INSERT 语句（默认 dry-run，仅打印）
+- 可使用 --execute 开关执行插入

+  python3 "学校历史数据迁移/04-insert_majors.py" --execute --host ...  (实际写入)

+05 - 按 dept_category 为同一学院下的专业排序并更新 order_num
+
+说明:
+- 在目标表（默认 `sys_dept`）中查找所有 dept_category 以 "zy-" 开头的专业记录
+- 按照 `parent_id`（学院）分组，对于每个组按照 `dept_category` 排序
+- 为排序后的记录按序设置 `order_num`（从 1 开始递增）
+- 支持 dry-run（仅打印 SQL）和 --execute（真正更新数据库）
+
+用法示例:
+  python3 "学校历史数据迁移/05-sort_majors_by_dept_category.py" --host localhost --user root --password secret --database hzdyjs_xg --dry-run
+  python3 "学校历史数据迁移/05-sort_majors_by_dept_category.py" --execute --host ...

+从 his_xssj 表把历史学生数据同步到 xg 系统表
+
+主要写入表：
+ - xg_student_msg
+ - sys_user
+ - sys_user_role
+
+特性：
+ - 同步前提示是否清空 xg_student_msg（需用户确认）
+ - 跳过 班级编号 为 '#YDQX#' 或 空字符串 的记录
+ - 批量插入并分批提交，包含简单的重试机制
+ - 通过 sys_dept 表查找班级/专业/学院信息；通过 xg_class_msg 获取班级关联字段
+ - 字段映射/清洗遵循项目要求（见任务描述）
+
+注意：此脚本依赖同目录下的 `db_config.py` 提供 `DB_CONFIG` 与 `TABLE_MAPPING`
