I have a weird situation here. Here is the script:

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

SQL Server is too smart and doesn't want to execute this script because the second line contains a field which does not exist. Well, I know that because I want to create it in the first line. But, because it validates the entire script before starting, I cannot execute this.

Any idea?
