Manual:Externallinks table/pl

Tabela externallinks jest miejscem, gdzie MediaWiki przechowuje dane o linkach zewnętrznych.

Tabela ta została wprowadzona w wersji 1.5.

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

el_from
Identyfikator strony, która zawiera link.

el_to
Adres URL 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'.

el_index_60
This is el_index truncated to 60 bytes to allow for sortable queries that aren't supported by a partial index.

@todo Drop the default once this is deployed everywhere and code is populating it.
