    <th>BASIS FOR COMPARISON</th> <th>PRIMARY KEY</th> <th>CANDIDATE KEY</th>
    Basic There can be only one primary key in any relation. There can be more than one candidate key in a relation.
    NULL No attribute of a Primary key can contain NULL value. The attribute of a Candidate key can have NULL value.
    Specify It is optional to specify a primary key for any relation. There can not be a relation without candidate key specified.
    Feature Primary key describes the most important attribute for the relation. Candidate keys present candidates that can qualify for Primary Key.
    Vice-Versa A primary key is a candidate key. But it not compulsory that each candidate key can be a primary key.
