How to Fix: Sql Server 'Saving changes is not permitted' error ► Prevent saving changes that require table re-creation
Error occurs when trying to change data type in SQL Server table design.
📋 Table of Contents
When you create a table in SQL Server and try to edit the table design, such as changing a column type from int to real, you receive the error message 'Saving changes is not permitted.' This occurs because the change requires the existing table to be dropped and re-created. However, this can be prevented by using a different data type that does not require table re-creation.

✅ Best Solutions to Fix It
Method 1: Using a Compatible Data Type
- Step 1: Change the column type to real using the following command: `ALTER TABLE table_name ALTER COLUMN column_name REAL;`
Method 2: Using a View or Stored Procedure
- Step 1: Create a view or stored procedure that wraps the original table, and use this new view or procedure to edit the data type.
💡 Conclusion
By using a compatible data type or creating a view or stored procedure, you can prevent the 'Saving changes is not permitted' error and edit your table design without having to re-create the table.
