-- =============================================================
-- 租户用户表补齐列：yz_system_tenant_user
-- 变更：
--   group_id  bigint unsigned NOT NULL DEFAULT 0  角色ID 关联 yz_system_admin_role(id, cid=2)，0-未分配(视为全权限)
--   org_id    bigint unsigned NOT NULL DEFAULT 0  所属组织(部门)ID 关联 yz_backend_organization(id)，0-未分配
-- 本脚本可重复执行：列不存在时才执行 ALTER，已存在自动跳过（不再报 1060 Duplicate column）。
-- 运行：mysql -h<host> -P<port> -u<user> -p <db> < alter_system_tenant_user_columns.sql
