-- 组织架构模块：表名去掉 erp 字样，改为租户端通用命名
--   yz_backend_erp_organization -> yz_backend_organization
--   yz_backend_erp_employee     -> yz_backend_employee
--   yz_backend_erp_position     -> yz_backend_position
--
-- 组织架构由进销存（ERP）与办公自动化（OA）共用同一份数据，通过 tid 实现租户间隔离。
-- 执行前请确认当前数据库字符集为 utf8mb4，并先备份这三张表。
--
-- 说明：脚本可重复执行。如果旧表不存在（全新环境），RENAME 会被跳过，
--       后面的 CREATE TABLE IF NOT EXISTS 会建出目标表结构。

-- ---------------------------------------------------------------------------
-- 1. 重命名已有表（仅当旧表存在且新表不存在时执行）
