Translators of board seat election pages per language and volume

For a given prefix of translatable pages, take all translators for the latest versions of translation units (otherwise someone fixing their own typos would look a prolific translator) and order them by language and translation volume.

SQL

use metawiki_p;

SELECT
	user_name as user,
	substring_index(page_title, '/', -1) AS language,
	count(*) AS no_translations,
    CONCAT('* {{target | page = User:', user_name, ' | site = meta.wikimedia.org}}')  AS url
FROM
	page
LEFT JOIN
	-- Take only the latest revision of each translation to simplify
	revision ON (page_id = rev_page AND page_latest = rev_id)
LEFT JOIN
	user ON (rev_actor = actor_id)
WHERE
	page_namespace = 1198 AND
	-- Must use the database format for titles, e.g. use underscores instead of spaces
	-- % means any string
	(page_title LIKE 'Affiliate-selected_Board_seats/2019/%' OR page_title LIKE 'Affiliate-selected_Board_seats_2019_election/%' )
GROUP BY
	user, language
HAVING
    no_translations > 1
ORDER BY
	language, no_translations DESC;
