-- 租户套餐 + 用户数配额（平台端「租户套餐」功能）
--
-- 业务说明：
--   1. 套餐（yz_system_tenant_package）决定租户能开通哪些功能模块
--      （模块取自 yz_system_modules，如 erp / oa / crm / cms），
--      租户绑定套餐后，租户端菜单按套餐包含的模块过滤（未包含的整块菜单不展示）。
--   2. 所有租户都有用户数上限（yz_system_tenant.user_quota，默认 20），
--      租户用户数达到上限后不允许再新增账号，需要先增购用户数：
--        · 单个增购：按套餐的 extra_user_price（如 200 元/人）
--        · 套餐增购：按 yz_system_tenant_user_quota_package 配置的规格（如 5人/500元）
--      每次增购写入 yz_system_tenant_quota_order 记录，并累加到租户的 user_quota。

-- 7) 预置套餐功能模块（按套餐 code + 模块 code 幂等插入）
--    注意：MySQL 的派生表不能引用外层字段，因此这里把「已存在的关联」整表materialize 成 ex，
--    再在 WHERE 中与外层套餐/模块做关联，既避免了「不能 SELECT 目标表」，也保证可重复执行。
--    基础模块：基础设置(basicSettings)、系统管理(systemManager)、便捷工具(bianjiegongju)

-- 8) 预置用户数加购套餐（5人 500元；可按需在平台端维护更多规格）
INSERT INTO `yz_system_tenant_user_quota_package` (`name`, `user_count`, `price`, `sort`, `status`, `remark`, `create_time`, `update_time`)

-- 9) 存量租户兜底：未绑定套餐的存量租户绑定「企业全功能版」，
--    避免上线后老租户因套餐未配置而看不到原有功能菜单；
--    之后可在「租户管理 → 编辑 / 套餐与用户数」中按实际购买情况改为 ERP/CRM 等套餐。
--    （若没有 all 套餐，则退回绑定默认套餐）

-- 10) 平台端菜单：基础设置 → 租户套餐（仅平台端可见）
--     pid=17 为「基础设置」菜单；若环境中 17 不是基础设置，请在平台端「菜单管理」里手工挂载本页面：
--     组件路径 /basicSettings/tenantpackage/index.vue，路径 /basicSettings/tenantpackage
INSERT INTO `yz_system_menu` (`pid`, `title`, `path`, `component_path`, `icon`, `sort`, `status`, `is_visible`, `views`, `type`, `permission`, `creater`, `remark`, `create_time`, `update_time`)

   AND EXISTS (SELECT 1 FROM (SELECT `id` FROM `yz_system_menu` WHERE `id` = 17 AND `delete_time` IS NULL) t2);

-- 11) 【按需执行】存量租户套餐调整
--     本脚本第 9 步只处理「package_id 为空/0」的租户；若存量租户已被绑定为「基础版」，
--     上线菜单按套餐过滤后，这些租户将看不到 进销存/OA/CRM/网站管理 等菜单。
--     如需要让老租户保留原有全部功能，按下面的语句把它们改为「企业全功能版」
--     （或改成各自实际购买的套餐；也可直接在平台端「租户管理 → 编辑」里选择套餐）。
--
-- UPDATE `yz_system_tenant`
--    SET `package_id` = (SELECT p.`id` FROM (SELECT `id` FROM `yz_system_tenant_package` WHERE `code` = 'all' AND `delete_time` IS NULL ORDER BY `sort`, `id` LIMIT 1) p)
--  WHERE `id` IN (1, 2);   -- ← 改成你的租户ID，或去掉 WHERE 批量处理

-- 校验：套餐与模块
