The SQL code that creates the MySQL/MariaDB core tables for any MediaWiki version is in the maintenance/tables.json source file, which is then transformed into maintenance/tables-generated.sql.

Prior to MediaWiki 1.35, the SQL code that created the core tables for any MediaWiki version—with extensive comments—was in the maintenance/tables.sql source file.

Up to MediaWiki 1.37 maintenance/tables.sql continued to be partially in use as some tables hadn't been migrated to maintenance/tables.json yet.

The most important tables are probably:

Versijų istorija

The following table depicts the range of MediaWiki versions over which each table has existed in the schema. Red rows indicate tables that are no longer used by the core nor added by the installer as of a particular version. They might however still be used by extensions. Note, table headings are repeated every 10 rows for clarity.

Duomenų bazių valdymo sistemos

In MediaWiki master, tables.sql is currently being migrated to maintenance/tables.json, and documenting comments should be found there instead of the resultant SQL files.

See the latest MariaDB/MySQL-compatible versions from Git: maintenance/tables.sql, maintenance/tables-generated.sql.

If using SQLite , the file maintenance/sqlite/tables-generated.sql and the unmigrated MySQL tables in maintenance/tables.sql should be viewed instead.

If using PostgreSQL , the files maintenance/postgres/tables.sql and maintenance/postgres/tables-generated.sql should be viewed instead.

If using Microsoft SQL Server, see maintenance/mssql/tables.sql. (removed in 1.34)

If using Oracle, see maintenance/oracle/tables.sql. (removed in 1.34)
