-- Experimental table definitions for Microsoft SQL Server with
-- content-holding fields switched to explicit BINARY charset.
-- ------------------------------------------------------------
-- SQL to create the initial tables for the MediaWiki database.
-- This is read and executed by the install script; you should
-- not have to run it by itself unless doing a manual install.
--
-- General notes:
--
-- The comments in this and other files are
-- replaced with the defined table prefix by the installer
-- and updater scripts. If you are installing or running
-- updates manually, you will need to manually insert the
-- table prefix if any when running these scripts.
--
--
-- The user table contains basic account information,
-- authentication keys, etc.
--
-- Some multi-wiki sites may share a single central user table
-- between separate wikis using the $wgSharedDB setting.
--
-- Note that when a external authentication plugin is used,
-- user table entries still need to be created to store
-- preferences and to key tracking information in the other
-- tables.
