SQL取决于声誉点

Question

如何通过信誉点获得用户级排序。
" super_admin"one_answers"员工"角色不应处于等级。

我的查询：
当我提出包括所有用户在内的请求时，排名很好，但是当我提出我的请求不包括具有" super_admin"one_answers"员工"角色的用户时，排名是错误的

SELECT u.id, u.rank 
FROM (
      SELECT u.id, @rownum := @rownum +1 AS rank
      FROM users u, (SELECT @rownum :=0 ) r
      ORDER BY u.reputation DESC, u.register_date ASC
     ) AS u
LEFT JOIN users_role ur ON ur.user_id = u.id
LEFT JOIN roles r ON r.id = ur.role_id
WHERE r.key_role NOT IN ('super_admin','staff')
AND u.id=3

表：

3     Registered user   registered_user

将排序移动到最外部查询：

（更新）

SELECT u.id, @rownum := @rownum +1 AS rank
FROM users u, (SELECT @rownum :=0 ) r
LEFT JOIN users_role ur ON ur.user_id = u.id
LEFT JOIN roles r ON r.id = ur.role_id
WHERE r.key_role NOT IN ('super_admin','staff')
ORDER BY u.reputation DESC,  u.register_date ASC
