By default SSMS 2008 does not allow table changes that require the table to be dropped and recreated. However some changes can only be done this way. I would disable that check but keep in mind that such changes could be slow on big tables.

>I have restored a database into SQL Server 2008. I want to try using the new DATE type column. So I got into SSMS 2008, went to one of the tables and tried to change the type that was SmallDateTime to Date. When attempting to save the changes I get the following message:
>

>Saving changes in not permitted. The changes you have made require the following tables to be dropped and re-created. You have either made changes to a table that can't be recreated or enabled the option to Prevent saving changes that require the table to be re-created.
