What is the term for the candidate key other than the primary key in a relational database table?

The term for the candidate key other than the primary key in a relational database table is known as an "Alternate Key".

Here are the steps to understand this:

1. In a relational database table, a candidate key is an attribute or a set of attributes that can uniquely identify a tuple (row).

2. The primary key is a special type of candidate key that is chosen by the database designer to uniquely identify each tuple in a table.

3. However, there can be more than one candidate key in a table.

4. Any candidate key which is not chosen as the primary key is known as an "Alternate Key".

5. So, the term for the candidate key other than the primary key in a relational database table is "Alternate Key".
