Update ConfigMgr Site Description

I did an install of a secondary site and accidently put in the wrong description…

Anyway, easy to fix with some SQL commands.

If you use this you can see the current sitenames and descriptions (change CM_XYZ to your database name):

SELECT SiteCode, SiteName, SiteServerName
FROM CM_XYZ..SC_SiteDefinition

And here is the way to update it (Change to you database name and the site code of the site you want to change)

UPDATE SC_SiteDefinition
SET SiteName = 'My Site Description'
WHERE CM_XYZ.SiteCode = 'ABC'

FYI: When running this you will se “Updated X rows… Updated Y rows…” and so on.
