Sometimes you get a dialog box in SQL server table save not permitted,. It 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 or drop a column
- Change column nullable
- Change columns order
- Change column data type
How to change this option,
1) Go to Tools menu.
2) Select Options…
3) Expand Designers, and then click Table and Database Designers.
4) Select or clear the Prevent saving changes that require the table to be re-created check box.
