Abfrage für 'Themen ohne Antwort' replizieren

Daten & Berichterstattung

Hi there!

I’m hoping to understand what % of new topics in a given category didn’t receive a response in the first week and what % were solved in the first week. Here’s my query:

-- [params]
-- string :start_date = 2021-10-06
-- string :end_date = 2021-10-12

WITH solved_topics as
(SELECT
    t.created_at::DATE,
    t.id,
    count(distinct case when u.action_type=15 and u.created_at < (t.created_at + INTERVAL '1 week') and u.target_topic_id=t.id then 1 ELSE NULL END) as solves,
    count(distinct case when p.created_at < (t.created_at + INTERVAL '1 week') and p.topic_id=t.id and p.post_number>1 then 1 ELSE NULL END) as responses
from topics t
join user_actions as u
    on u.target_topic_id = t.id
join posts as p
    on p.topic_id = t.id
where t.created_at BETWEEN :start_date AND :end_date
AND t.user_id > 0
AND p.deleted_at is NULL 
AND t.category_id is NOT NULL 
group by t.created_at::DATE, t.id)

SELECT
    st.created_at as date,
    count(distinct st.id) as "Number of New Topics",
    sum(st.solves)::INT as "# Solved within a week",
    round(sum(st.solves)/count(distinct st.id), 2) as "% Solved",
    (count(distinct st.id) - sum(st.responses))::INT as "Topics with No Response in First Week",
    round((count(distinct st.id) - sum(st.responses))/count(distinct st.id), 2) as "% with No Response in First Week"
  
    from solved_topics as st
group by date
order by date asc

I’m sure there are prettier ways to do this, but I’ve spot-checked a number of dates, and these numbers are consistent with what I’m seeing by looking at individual topics.

I would assume that for any day within the past week, the report found at /admin/reports/topics_with_no_response should show the same number of topics with no response. In most cases it does; but in other cases it shows more topics with no response than I’m getting in my query.

Any ideas why this might be? Is there a way to see the query that drives the Topics with no response report so that I could compare/contrast?

Thanks in advance!

Als ich die Berichtsthemen ohne Antwort mit einer Analyse der Themenliste verglichen habe, stellte ich fest, dass die Zahl im Bericht größer ist, und schloss daraus, dass Themen, die nur Antworten vom ursprünglichen Autor haben, als ohne Antwort gezählt werden.
Ich kann nicht mit Sicherheit sagen, dass dies der Grund für den von Ihnen bemerkten Unterschied ist, da ich dies nicht überprüfen konnte, da Ihre Abfrage nicht die aktuellen Zahlen, sondern nur die Zahlen „nach 1 Woche“ liefert. Und ich bin nicht so gut in SQL.
