Manual:Text table/de

The text table holds the wikitext of individual page revisions. If using Postgres or Oracle, this table is named pagecontent. Extensions may also store data here.

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.

old_id
