For changing the language of all sites in the content database to Dutch the query would be:

UPDATE dbo.Webs SET Language = 1043

Changing the language of one site collection can be done with:

UPDATE dbo.Webs SET Language = 1043 WHERE SiteId = [[SiteCollectionId]]

And for changing the language of a single web or subsite you can use:

UPDATE dbo.Webs SET Language = 1043 WHERE Id = [[WebId]]
