SQL Server 2008 change tracking and primary keys

Question

I needed to set change tracking in sql server 2008 table to true but it gave an error that the table has to have a primary key

1. Is there a way to enable change tracking without setting a primary key in my table
2. Is it a good programming practice not to set primary keys? I am creating a system but i don't want to set them on SQL tables

Answer 1

The Table must have primary key in order to enable Change tracking

Having primary keys on a table infarct is a good programming practice.

Answer 2

You can enable Change Tracking on a table which has Primary key. It is must. Because Change Tracking works based on Primary key in a table.
