Saving changes is not permitted

I’ve run into this problem a couple of times now and it’s really annoying every time it happens. I created a table in SQL Express using the SQL Management Studio and saved it. I then tried adding some new columns to the table but when I saved it again the following error appeared:

“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.”

The dialog is really helpful:


The solution is as follows:

  1. Go to Tools > Options…
  2. Select the Designers node.
  3. Uncheck the Prevent saving changes that require table re-creation option.



Job done.
