-- 修复 menu 表 CreateUserId / UpdateUserId 非法 GUID（如 "0"）
-- 症状：登录或 GET /rbac/menu/get-menu-tree → Could not parse CHAR(36) value as Guid: 0
--
-- ⚠️ 在 RBAC 库执行（不是 OMS 业务库 fake_simple_admin）
-- ⚠️ WHERE 中禁止写 CreateUserId = 0（整数），会触发 1292 GUID 转数字错误

-- 1) 管理员 GUID：优先 admin 账号，否则取第一个用户
SET @ADMIN_USER_ID = (
  SELECT `Id` FROM `user`
  WHERE `Account` = 'admin' AND (`IsDeleted` = 0 OR `IsDeleted` IS NULL)
  LIMIT 1
);
SET @ADMIN_USER_ID = IFNULL(
  @ADMIN_USER_ID,
  (SELECT `Id` FROM `user` WHERE `IsDeleted` = 0 OR `IsDeleted` IS NULL ORDER BY `CreateTime` LIMIT 1)
);

SELECT @ADMIN_USER_ID AS admin_user_id_used;

-- 2) 诊断：修复前查看脏数据
SELECT `Id`, `Name`, `Route`, `CreateUserId`, `UpdateUserId`
FROM `menu`
WHERE (`CreateUserId` IS NOT NULL AND `CreateUserId` NOT REGEXP '^[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}$')
   OR (`UpdateUserId` IS NOT NULL AND `UpdateUserId` NOT REGEXP '^[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}$');

-- 3) 小红书种子菜单（按 Id 精确修复）
UPDATE `menu`
SET `CreateUserId` = @ADMIN_USER_ID,
    `UpdateUserId` = @ADMIN_USER_ID
WHERE `Id` IN (
  'a1b2c3d4-e5f6-7890-abcd-ef1234567801',
  'a1b2c3d4-e5f6-7890-abcd-ef1234567802',
  'a1b2c3d4-e5f6-7890-abcd-ef1234567803',
  'a1b2c3d4-e5f6-7890-abcd-ef1234567804',
  'a1b2c3d4-e5f6-7890-abcd-ef1234567805',
  'a1b2c3d4-e5f6-7890-abcd-ef1234567806',
  'a1b2c3d4-e5f6-7890-abcd-ef1234567807',
  'a1b2c3d4-e5f6-7890-abcd-ef1234567808'
);

-- 4) 兜底：全表非法 GUID（字符串比较，勿用 = 0）
UPDATE `menu`
SET `CreateUserId` = @ADMIN_USER_ID
WHERE `CreateUserId` IS NOT NULL
  AND `CreateUserId` NOT REGEXP '^[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}$';

UPDATE `menu`
SET `UpdateUserId` = @ADMIN_USER_ID
WHERE `UpdateUserId` IS NOT NULL
  AND `UpdateUserId` NOT REGEXP '^[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}$';

-- 5) 修复后应无结果
SELECT `Id`, `Name`, `CreateUserId`, `UpdateUserId`
FROM `menu`
WHERE (`CreateUserId` IS NOT NULL AND `CreateUserId` NOT REGEXP '^[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}$')
   OR (`UpdateUserId` IS NOT NULL AND `UpdateUserId` NOT REGEXP '^[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}$');
