How to prevent “Saving changes is not permitted” on SQL Server 2008

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 will result by default in the following dialog:

“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.”

To be able to make a change in your table structure, you’ve just to follow these steps:

  • Tools > Options
  • Select the tab Designers and choose Tables and designers
  • uncheck the option: “Prevent saving changes that require table re-creation”

Now you can save changes.
