Super Key is a key which is used to define uniqueness of a row with the collection of more than one column
Eg:- There is Customer Table
The Primary Key will be CustomerID field but this cannot be termed as a Super key
To be a Super key we can club 2 columns such as
CustomerID and LastName of the Customer.
If we see the above eg over here we have club 2 columns and uniquely identified a ROW
