USE bnwiki_p;: Specifies the use of the bnwiki_p database for the query.
SELECT CONCAT('# [[', page.page_title, ']]'): Selects pages where the main namespace redirects to the draft namespace, and it constructs a formatted output using the CONCAT function. It adds a prefix and suffix to the page_title to create a link to the draft namespace.
FROM page: Specifies the main table to retrieve data from.
JOIN redirect ON page.page_id = redirect.rd_from: Joins the page table with the redirect table based on the page ID.
JOIN page AS target_page ON redirect.rd_namespace = target_page.page_namespace AND redirect.rd_title = target_page.page_title: Joins the redirect table with the page table (aliased as target_page) based on the namespace and title to identify the target page of the redirect.
WHERE page.page_namespace = 0 AND target_page.page_namespace = 118;: Filters the results to include only those where the page is in the main namespace and the target page is in the draft namespace.
The output of this query will provide a list of formatted links to pages in the main namespace that redirect to the draft namespace.
