Turn off the identity column by editing the table definition after opening in the design mode. After updating the value you can change it again into the identity column. Alternativel, you can delete the existing record and enable the identity insert and insert the new record for the desired column values as shown below. set identity_insert YourTable ON You can also reset the identity column values by the new one as shown below. DBCC CHECKIDENT( 'tableName' , RESEED, NEW_RESEED_VALUE) One thing you need to remember even after removing the identity column you need to insert / update with the unique value as you have said your column ins the primary key which does not accept the duplicate values in any case.
