Manual:Externallinks table/pl

The externallinks table is where MediaWiki stores and tracks external links. This table was introduced after 1.5.

el_id
Klucz podstawowy. Presently not used for anything, but will help with online schema changes.

el_from
The page identifier of the referring wiki page.

el_to
The actual URL itself. It is passed to the browser.

el_index
This is the same URL as  search-optimized: username and password information is stripped, and the other components are reversed for faster searching, so   becomes , which allows searches of the form 'Show all links pointing to *.example.com'.
