Read history for a particular category

Is there a way to write this specific query:

  • For topics in category (category id: 34) viewed by user(s) not in group (executive_board)
    • Display user, display topic, display when viewed.
Is it possible to get a list of topics in a category read by a specific user?

Curiosamente, esto se actualizó automáticamente. Y es lo suficientemente relevante como para que me encantaría que alguien tuviera una respuesta.

Sí, parece que has esperado un tiempo por este. :slight_smile:

¿Creo que algo como esto podría hacerlo? (Necesitarías encontrar el group_id para tu executive_board y cambiarlo por el group_id = 3)

SELECT tu.user_id,
       tu.topic_id,
       tu.last_read_post_number,
       tu.last_visited_at AS read
FROM topics t
LEFT OUTER JOIN topic_users tu ON t.id = tu.topic_id
WHERE tu.user_id NOT IN (SELECT user_id
    FROM group_users
    WHERE group_id = 3)
AND t.category_id = 34
AND tu.last_visited_at IS NOT NULL
ORDER BY tu.last_visited_at DESC
