Manual:Text table/de

Die text-Tabelle enthält Metadaten für jede Bearbeitung, die an einer Seite innerhalb des Wikis vorgenommen wurde. If using Postgres or Oracle, this table is named pagecontent. können hier ebenfalls Daten speichern.

Field names are a holdover from the revisions table in MediaWiki 1.4 and earlier.

If you updated your wiki from MediaWiki 1.4 or older to a newer version, and if you have then run update.php at least once, you will still have old columns in the text table, whose contents have been migrated to the ' table and the ' table (content is copied, not cut). These columns in the text table will not be used anymore. All fields in the text table except old_id, old_text and old_flags are not needed anymore and can be safely deleted.

Text content can be compressed or stored externally, and thus difficult to get from this table. The maintenance script can be used to retrieve the text of a given.

Extensions can add other custom flags.

This table can also hold metadata of files if the metadata is too big to store in img_metadata, oi_metadata or fa_metadata.
