Introduction
SQL Server 2008 Error: Saving changes is not permitted.
Solution
While creating and editing a database in SQL Server 2008 I ran into a brick wall, or a 'by design' feature of the Database Management Studio.
When you design a table in a database and then try to make a change to a
table structure that requires the table to be recreated, the Database
Management Studio will not allow you to save the changes. This is caused by a configuration setting that results in the following dialog:
This dialog states: "Saving changes is 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 re-created or enabled the option Prevent saving changes that
require the table to be re-created."
You can only react by clicking the Cancel button. And then Management Studio shows this dialog:
So what do you want to do to configure the setting with the value you want (should be the default setting!)?
Go to: Tools > Options
“Designers –> "Table and Database Designers”
And uncheck the option: "Prevent saving changes that require table re-creation". Once you save the changes it will work.
