Change Auto-Increment ID in SQL Server

In SQL Server, the value of an auto-incremented id is controlled by an Identity column. To modify the value of an auto-incremented id, you can use the following method:

1. To use the SET IDENTITY_INSERT statement: Before executing an INSERT statement, use the SET IDENTITY_INSERT table name ON statement, so that you can manually insert a specified value for the ID. For example:
2. Turn on identity insert for the table, insert values for specified columns with a specific ID, then turn off identity insert.
3. You can use the DBCC CHECKIDENT statement to adjust the current value of an auto-incrementing ID. For example:
4. Reset the identity column value to a new value in the specified table.

Be aware that changing the value of an auto-incremented ID may cause data consistency issues, so it is advised to carefully consider before making any modifications. Furthermore, altering the auto-incremented ID can compromise the integrity of the database, so it is not recommended to frequently change it in a production environment.
