--- 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.
