When trying to modify a column data type in a 3rd party database, I get a message stating that "Saving changes is not permitted" and that tables would have to be dropped or recreated.
Is there a prevent option or something I need to change?
I would be weary about changing it if it is a vendor database - might void your warranty or break their code or middle tier applications.
However, if you do want to do it, Tools->Options->Designers->Table and Database Designers and uncheck the "Prevent saving changes that require table recreation".
Whenver possible, you should use an ALTER TABLE statement instead of changing the table thru SSMS "Design". SSMS is not only much more overhead, but it can sometimes "hang" and/or cause strange errors.
