In some large wikis one might find some rare web pages that don't have categories (for example, when these pages were created, the creator forgot to add a category).
How to know what are all the MediaWiki web pages without categories?
I didn't find such a list web-page at special:special_pages
(translated from Hebrew).
cl_from
and the category ascl_to
. Easiest way is probably to do an outer JOIN, with a test forWHERE cl_to is null
. {Looks like an SQL course might be handy!}
