Update values in identity column

Question

How do I override the identity column in MSSQL? I tried :

    SET IDENTITY_INSERT GeoCountry ON
    UPDATE GeoCountry SET CountryID = 18 WHERE C         


        

Answer 1

You cannot update the Identity Column in SQL Server. You have to delete the original record, then Insert the record with the Identity value because there is no support for updating an identity value.

set Identity_Insert [ColumnName] On Insert identity and additional information previously stored in that record set Identity_Insert [ColumnName] Off
