muyu-apiserver/deploy/mysql/migrations/20260329_add_tenant_id_to_legacy.sql

-- Migration: Add tenant_id to all legacy tables
-- Safe to re-run: uses column existence checks via PREPARE/EXECUTE

USE `muyu_wms`;

-- Helper: add tenant_id column if not exists
-- Repeated for each table because MySQL 8 lacks ADD COLUMN IF NOT EXISTS.
