Saving Changes Is Not Permitted SQL Server: Understand and Troubleshoot the Issue

Hello Dev, in this journal article, we will talk about the common error message that SQL Server users encounter, “Saving changes is not permitted.” This is a frustrating error that can prevent you from making critical updates to your database. In this article, we will help you understand what triggers this error and provide you with a step-by-step guide on how to troubleshoot it. Let’s begin!

What Causes the Error Message “Saving Changes Is Not Permitted”?

Before we dive into the troubleshooting steps, it’s essential to understand what triggers this error message. When you make changes to your SQL Server database using the Management Studio, you may encounter the error message that reads:

“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 you have enabled the option Prevent saving changes that require the table to be re-created.”

This error occurs due to the SQL Server Management Studio’s default behavior to prevent users from making schema changes to tables that could result in data loss or table recreation. In the next few sections, we will walk you through the possible reasons for this error message and explain how you can resolve them.

Reason 1: Prevent Saving Changes That Require Table Recreation

The first reason that can cause this error message is the default option “Prevent saving changes that require table recreation” enabled in SQL Server Management Studio. This option prevents users from accidentally dropping or altering a table that could cause data loss or inconsistencies in the database.

To disable this option, follow these steps:

1. Open SQL Server Management Studio.
2. Go to the Tools menu and select “Options”.
3. Navigate to the “Designers” tab, and under “Table and Database Designers”, uncheck the box next to “Prevent saving changes that require table re-creation”.
4. Click “OK” to save the changes.

Reason 2: Schema Changes Require Table Recreation

The second reason that can cause the error message “Saving changes is not permitted” is when schema changes require table recreation. When you modify a table’s schema, SQL Server may need to drop and recreate it with the new schema. However, if the table has dependencies, such as foreign key constraints, the table recreation may fail.

To resolve this issue, you can follow these steps:

1. Open SQL Server Management Studio.
2. Make sure the option “Prevent saving changes that require table re-creation” is unchecked. You can follow the steps mentioned in reason one to disable the option if required.
3. Right-click on the table that you need to modify and select “Design”.
4. Make the necessary schema changes.
5. Highlight the changes you made in the table designer and use the “Generate Change Script” option instead of clicking “Save”.
6. Review the change script and execute it to apply the changes to the table.

Reason 3: Saving Changes to System Tables

The third reason that can cause the error message “Saving changes is not permitted” is when you try to modify system tables or their indexes. This restriction prevents users from accidentally making changes to system tables and causing inconsistencies in the database.

To resolve this issue, you can follow these steps:

1. Open SQL Server Management Studio.
2. Make sure the option “Prevent saving changes that require table re-creation” is unchecked. You can follow the steps mentioned in reason one to disable the option if required.
3. Right-click on the table that you need to modify and select “Script Table as…” and then select “DROP and CREATE to…”.
4. Save the script generated by SQL Server Management Studio.
5. Edit the script and remove the restriction on modifying system tables or their indexes.
6. Execute the modified script to apply the changes.
