Question
What is the term for the candidate key other than the primary key in a relational database table?
Solution
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:
-
In a relational database table, a candidate key is an attribute or a set of attributes that can uniquely identify a tuple (row).
-
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.
-
However, there can be more than one candidate key in a table.
-
Any candidate key which is not chosen as the primary key is known as an "Alternate Key".
-
So, the term for the candidate key other than the primary key in a relational database table is "Alternate Key".
