The "following key" typically refers to a specific key or command used in various contexts, such as computer programming, software applications, or gaming.

If you provide more context, I can offer a more tailored explanation.
All Primary keys are definitely Candidate Keys. A Candidate key is one which can be used as a Primary key that is not null and unique. That is one of the candidate keys can be chosen as a primary key.A Candidate key is a Unique Key and it can be used to find out any particular Tuple (row) in a table.
