declaration of element contributor in the DTD is not complete
The declaration of element contributor does not include the case where there is no id nor ip, and instead contributor has "deleted" as an attribute. I came across one instance where neither id nor ip were present.

Getting full list of pages
The SQL select page_title from wiki_page where page_namespace=0 was from 2007 and does not work now.
 * select page_title from page where page_namespace=0 -- returns blobs.
 * However, this works for me -- select CONVERT(page_title using utf8) from `page` where page_namespace=0

My road to update a MediaWiki 1.23 with PostgreSQL 8.4.9 to MediaWiki 1.30 with MariaDB 10.1
Ordinary update failed (could be that the OS was old). Using PostgreSQL for MediaWiki was a misstake, so I want to use MariaDB. This is how I exported ALL pages (with complete history) from the old wiki and import them into the new wiki.

 * 1) Read all the steps below before you start!
 * 2) Installed MediaWiki 1.30 and MariaDB 10.1. Did the basic setup.
 * 3) Add/change some parameters needed for my export on the "from" wiki (LocalSettings.php)
 * 4) Add/change some parameters needed for my import on the "target" wiki (php.ini)
 * 5) Find the name of every page in every namespace in the wiki. The SQL part (after the -c) should work on "any" SQL. The sed part change "|" into ":". The split makes the output into files with maximum 100 wiki pages each.
 * 6) For each file from the command above, copy the text into Special:Export and export it. Then rename it with the same number as the input file (so you keep track).
 * 7) Import the file with Special:Import.
 * 8) Repeat until all files are exported and imported.

Export table made with a template to join data
Good morning,

I created a table with a lot of columns thanks to a template. I used this template to join data from different pages, thus it contains many different. I only found how to export each when I actually want to export the entire table. Does anyone have a solution for me? Thank you in advance. AnaisBce (talk) 07:49, 31 August 2018 (UTC)
