What is the difference between Unique key constraints and Primary key constraints?
The distinction between a UNIQUE constraint and a Primary Key is that a Primary Key can only be defined once per table, whereas a UNIQUE constraint can be defined multiple times. The constraints on the Primary Key are not nullable. UNIQUE constraints have the potential to be nullable.
