When you create a table in SQL Server and save it, sometimes, if you try to edit the table design you get this error:

Saving changes is not permitted. The change you have made requires the following table to be dropped and re-created. You have either made changes to a table that can’t be recreated or enabled the option prevent saving changes that require the table to be re-created.

This can happen also if the table is a new empty table, never used.

From Save (Not Permitted) Dialog Box on MSDN :

The Save (Not Permitted) dialog box warns you that saving changes is not permitted because the changes you have made require the listed tables to be dropped and re-created.

The following actions might require a table to be re-created:

  • Adding a new column to the middle of the table
  • Dropping a column
  • Changing column nullability
  • Changing the order of the columns
  • Changing the data type of a column

To change this option, on the Tools menu, click Options, expand Designers, and then click Table and Database Designers. Select or clear the Prevent saving changes that require the table to be re-created check box.
