Continuando a discussão de Como conceder forçadamente todas as medalhas via linha de comando:

Prezada comunidade, alguém pode ajudar a otimizar esta consulta SQL para uma medalha personalizada?

Ela conta o número de palavras e o número de imagens postadas em tópicos de uma categoria específica e concede uma medalha com base nisso.

Uma nova análise por alguns olhos atentos pode ser muito útil :slight_smile: Muito obrigado.

Corrigido por conta própria:

WITH summary AS (

  t.id AS topic_id,
  t.created_at AS created_at,
  t.user_id AS user_id,
  COUNT(DISTINCT p.created_at::date) AS num_days,
  SUM(p.word_count) AS num_words,
  SUM(
    length(raw) * 2
      - length(replace(raw, '![IMG', '1234'))
      - length(replace(raw, '[img]', '1234'))
  ) AS num_images
FROM topics t
  LEFT JOIN posts p ON p.topic_id = t.id
WHERE
    t.category_id = 17
    AND t.archived = false
    AND t.closed = false
    AND t.visible = true
    AND p.deleted_at IS NULL
    AND p.user_id = t.user_id
GROUP BY t.id

)

SELECT s.*,
  CURRENT_DATE AS granted_at
FROM summary s
WHERE
    num_days >= 10
