How is the orderby function used in a database?

In databases, the ORDER BY statement is used to sort the query results by one or more columns. It can sort the results in ascending (ASC) or descending (DESC) order, with ascending being the default option.

Syntax:
SELECT column1, column2, …
FROM table_name
ORDER BY column1 [ASC|DESC], column2 [ASC|DESC], …

Column names 1, Column names 2, … are the columns that need to b queried, the table name is the name of the table to be queried, and Column names 1, Column names 2, … are the column names to be sorted in the result. ASC and DESC are optional sorting orders, ASC represents ascending order (default), and DESC represents descending order.

Retrieve the names and ages of users from the database, sorting them in descending order by age and ascending order by name.

This example will query the name and age columns from the users table, ordering by the age column in descending order. If the age is the same, it will then order by the name column in ascending order.
