Question

with baseQuery as(
                  select id,
                  (select sum(calories) from dailytable where user_id in (select user_id from group_members where group_id=132 and status = 'accepted' and user_id=users.id)) as total_calories
                  from users where id in (select user_id from group_members where group_id=132 and status='accepted'))
                  select *,dense_rank() over(order by total_calories desc nulls last) as rank
from baseQuery;

这是我的查询和输出如下。

    id    total_calorie         rank
    121   2516.054250000001     1
    25    897.0234000000002     2
    120   784.13784             3

我想只得到用户ID 120的等级，但是当我在上面的查询中放置条件时它将等级返回为1而不是3。

我该如何解决这个问题？

您可以在第一个CTE之后添加另一个CTE：

with 
baseQuery as 
(
    select id, (select sum(calories) from dailytable where user_id in (select user_id from group_members where group_id=132 and status = 'accepted' and user_id=users.id)) as total_calories
    from users where id in (select user_id from group_members where group_id=132 and status='accepted')
), 
ranked_query as 
(
    select *,dense_rank() over(order by total_calories desc nulls last) as rank
    from baseQuery
)
select * from ranked_query where id = 120;
