Is there any way to disconnect active users from a live database and lock them out till the database strucure has been updated?
Something like this should work for you.
use <db>
go
--remove all active users from the database
Alter database <db> set SINGLE_USER with ROLLBACK IMMEDIATE
go
--make changes to the database structure on this connection
go
--let users back in
Alter database <db> set MULTI_USER
