The MIN() Function

MIN() - this function returns the lowest value in a particular column.

Let’s look at an example:

12
SELECT MIN(population) FROM country;
copy

Explanation: Here, MIN() returns the smallest population value in the country table.

Task

Write an SQL query to get the smallest value from the surfacearea column in the country table.

Here's a short example of the country table:
