bookSorting Data

Furthermore, we have the ability to sort the data we receive in a specific order. To achieve this, we first retrieve the data using the SELECT operator and subsequently apply the ORDER BY clause. This clause accepts the names of columns based on which the output will be sorted. Let's explore an example to enhance our comprehension:

123
SELECT continent FROM country ORDER BY continent;
copy

Note

It is essential that the ORDER BY clause comes last in the SELECT statement.

Explanation: In the example, you can observe that the ORDER BY clause sorts the data based on the continent column.

Task

First, select the capital column from the country table. Then, sort the data from the capital column, retrieved using the SELECT statement.

Here's a short example of the country table:
