Just put them in two separate batches:

ALTER TABLE [Advertis] ADD [AddUserTemporary] int
GO
UPDATE [Advertis] SET [AddUserTemporary]=AddUser

or if you have to do this from an application:

EXEC sp_executesql N'ALTER TABLE [Advertis] ADD [AddUserTemporary] int'
EXEC sp_executesql N'UPDATE [Advertis] SET [AddUserTemporary]=AddUser'
