Manual:Watchlist table/es

The watchlist table for each registered user contains his or her id and for all the pages the user watches, the namespace number, the page title without namespace, and a notification timestamp, used for page change notification.

Note: MediaWiki works with the assumption that when people watch pages they either watch both the talk page and the normal page, or neither. That means that for each watched page MediaWiki always automatically adds two entries: One for the page and one for its talk page. E.g. when the user watches the Main Page, then there will be two rows in the database table: One for the Main Page in namespace 0 and one for the Main Page in namespace 1 (which is the according talk page). Missing page rows are added by the maintenance script update.php.

wl_user
This is the key to.

wl_namespace
This is the key to.

wl_title
This is the key to.

wl_notificationtimestamp
This is the timestamp of the first change to the page made by another user after the last visit by the watching user; the timestamp is cleared when the user visits the page. When the timestamp is updated, notification email may be sent.

The timestamp is always cleared (made NULL) when the user visits the page, whatever their personal settings, as long as either either of $wgUseEnotif or $wgShowUpdatedMarker is true.

Since, the timestamp update may be deferred to the job queue.
