Continuando a discussão de [Como conceder forçadamente todas as medalhas via linha de comando](https://meta.discourse.org/t/how-to-force-grant-all-badges-from-command-line/137960/19):

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 🙂 Muito obrigado.

```sql
WITH

personal_pages AS (
  SELECT *
  FROM topics
  WHERE category_id = 17
    AND archived = false
    AND closed = false
    AND visible = true
),

word_counts AS (
  SELECT p.id as post_id,
    p.word_count as num
  FROM posts p
),

image_count AS (
  SELECT p.id as post_id,
    length(raw) * 2
      - length(replace(raw, '<img', '123'))
      - length(replace(raw, '[img]', '1234')) as num
  FROM posts p
),

summary AS (
  SELECT 
    pp.id as topic_id,
    pp.user_id as user_id,
    COUNT (DISTINCT p.created_at::date) as num_days,
    SUM (wc.num) as num_words,
    SUM (ic.num) as num_images
  FROM personal_pages pp
  LEFT JOIN users u on u.id = pp.user_id
  LEFT JOIN posts p ON p.topic_id = pp.id
                   AND p.user_id = pp.user_id
  LEFT JOIN word_counts wc ON wc.post_id = p.id
  LEFT JOIN image_count ic ON ic.post_id = p.id
  WHERE u.staged = false
    AND p.deleted_at IS NULL
  GROUP BY pp.id, pp.user_id
)

SELECT summary.*,
  CURRENT_DATE as granted_at
FROM summary
WHERE num_days >= 10
  AND num_words >= 1000
  AND num_images >= 10

```
