-- ==========================================
-- 物业报修管理模块表名重命名脚本
-- 版本：V1.0.0
-- 功能：将现有pm_开头的表名重命名为hq_pm_开头
-- 作者：Cursor AI 辅助
-- 时间：2025-01-23
-- 目的：符合项目表名规范（后勤管理模块使用hq_前缀）
-- ==========================================

-- 设置字符集
SET NAMES utf8mb4;

-- 检查表是否存在并进行重命名
-- 注意：在重命名之前请确保没有其他进程在使用这些表

-- 1. 重命名报修工单表
-- 先检查表是否存在

-- 重命名主要业务表
