Manual:Watchlist table/ja

watchlist テーブルは、各登録利用者の ID とその利用者がウォッチしているすべてのページの利用者の、名前空間 ID、名前空間を除いたページ名、通知のタイムスタンプを格納します. ページの変更の通知に使用されます.

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_id
This is the primary key for the table.

wl_user
これは へのキーです.

wl_namespace
これは $user-namespace へのキーです.

wl_title
これは $user-title へのキーです.

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.
