To retrieve a record in multiple orders for different columns from the existing created table. Then we can use an ' ORDER BY ' Clause multiple times with ASC or DESC differently depending upon the requirement.
Suppose if we want to retrieve a record in ascending order of a first_name, And there are two or more records with the same first_name. So for the same first_name record, we want to retrieve its last_name in descending order.
Then we have to 1st declare first_name in ascending and 2nd declare last_name in descending.
In this 'ORDER BY first_name ASC, last_name DESC ' and 'ORDER BY last_name DESC, first_name ASC' both look the same, but both will retrieve different data
