Topic on Talk:Quarry

Hi, I am looking for a substitute for the talk page tool by DrTrigon (not working since a couple of month).It should list the names of all talk pages of the corresponding Wikipedia articles (e.g. in dewiki) that belong to a specified article category (including a depth of subcategorys that can also be scepicified, e.g. 10) and where the talk pages have been changend in the last e.g. 14 days. Is this possible with a query?

Deep category search with SQL is very difficult unless the depth of the category is one or two.

So if I use Petscan to give me a list of all sub categorys and the list is below the 65K query length limit and I paste it into the query (e.g. "...where category in ('American 3D films','Australian 3D films','Brazilian 3D films‎'...", will there be a way?

Probably yes:

USE enwiki_p;
SELECT rc_title FROM recentchanges JOIN categorylinks ON cl_from = rc_cur_id
WHERE rc_namespace = 1
AND cl_to IN ('American_3D_films', 'Australian_3D_films', 'Brazilian_3D_films‎', ...)
AND rc_timestamp >= DATE_ADD(NOW(), INTERVAL -14 DAY)
ORDER BY rc_timestamp;

Thanks for the query, but I get null results where there should be some. Query 27673, dewiki, article "S-Bahn Wien" in category "Bahnstrecke in Wien" had talk page contributions one week ago.

I forgot to highlight (and wanted to do so) that you need to include underscores (_) instead of spaces in category names.

I tried it both with underscores and spaces, but still no results, please see Query 27673.

Uh, I misunderstood your wish and assumed that the talk pages should be in the category, not the articles. This query should work:

USE dewiki_p;
SELECT rc_title, rc_timestamp FROM recentchanges
JOIN page ON rc_namespace = 1 AND rc_title = page_title AND page_namespace = 0
JOIN categorylinks ON cl_from = page_id
WHERE cl_to IN ('Bahnstrecke_in_Wien', 'Musiker_(Wien)')
AND rc_timestamp >= DATE_ADD(NOW(), INTERVAL -14 DAY)
ORDER BY rc_timestamp;

Just tested the new query, this is exactly what I was looking for. Thank you very, very much!
