Manual:oldimage/ja table
↑ Manual:コンテンツ | <translate> MediaWiki database layout</translate> | <translate> <tvar name=1>oldimage/ja</tvar> table</translate> |
oldimage テーブルは、ファイルの過去の版についての情報を保持します。 これは、既存のファイルの新しいバージョンがウィキにアップロードされる時に記録されます。 これらのファイルはフォルダー /image/archive に移されます。 Information on deleted images however will not be stored in the oldimage table; on deletion information is moved to the filearchive instead.
