Hi i want to update a single column of data that is part of a PK is this possible to do, the only way i can see how to do it, it to remove the PK change the data and reset the PK, but i don't think this is the correct way of doing it.
You can update data that is part of a primary key. If the column is defined as an IDENTITY column, you will need to issue SET IDENTITY INSERT ON before your update, and SET IDENTITY INSERT OFF immediately afterwards.
