Relatório do Painel - Tópicos sem Resposta

Olá Sophie,

Para modificar a consulta de forma que ela possa agregar tópicos sem respostas por ano, mês ou outros intervalos de tempo, você pode adicionar um parâmetro para especificar o intervalo desejado na função date_trunc para alcançar isso.

Por exemplo:

-- [params]
-- date :start_date = 2024-01-01    
-- date :end_date = 2025-01-01
-- null int :category_id
-- boolean :include_subcategories = false
-- text :interval = day -- Opções: day, week, month, year

WITH no_response_total AS (
  SELECT *
  FROM (
    SELECT t.id, t.created_at, MIN(p.post_number) first_reply
    FROM topics t
    LEFT JOIN posts p ON p.topic_id = t.id AND p.user_id != t.user_id AND p.deleted_at IS NULL AND p.post_type = 1
    WHERE t.archetype <> 'private_message'
      AND t.deleted_at ISNULL
      AND (
        :category_id IS NULL
        OR t.category_id = :category_id
        OR (
          :include_subcategories
          AND t.category_id IN (
            SELECT id FROM categories WHERE parent_category_id = :category_id
          )
        )
      )
    GROUP BY t.id
  ) tt
  WHERE tt.first_reply IS NULL OR tt.first_reply < 2
)

SELECT 
  date_trunc(:interval, nrt.created_at)::date AS period, 
  COUNT(nrt.id) AS topics_without_response
FROM no_response_total nrt
WHERE nrt.created_at::date BETWEEN :start_date AND :end_date
GROUP BY period
ORDER BY period ASC

Se você quisesse remover os parâmetros, poderia alternativamente usar uma consulta como:

WITH no_response_total AS (
  SELECT *
  FROM (
    SELECT t.id, t.created_at, MIN(p.post_number) first_reply
    FROM topics t
    LEFT JOIN posts p ON p.topic_id = t.id AND p.user_id != t.user_id AND p.deleted_at IS NULL AND p.post_type = 1
    WHERE t.archetype <> 'private_message'
      AND t.deleted_at ISNULL
    GROUP BY t.id
  ) tt
  WHERE tt.first_reply IS NULL OR tt.first_reply < 2
)

SELECT 
  date_trunc('year', nrt.created_at)::date AS period, 
  COUNT(nrt.id) AS topics_without_response
FROM no_response_total nrt
WHERE nrt.created_at::date BETWEEN '2024-01-01' AND '2025-01-01'
GROUP BY period
ORDER BY period ASC
