MySQL - SELECT the name that comes first alphabetically

Question

I have started to learn MySQL.

Here is the table world:

+-------------+-----------+---------+
|    name     | continent |  area   |
+--         


        

Answer 1

SELECT continent,
       name
FROM world x
WHERE name=
    (SELECT name
     FROM world y
     WHERE x.continent=y.continent
     ORDER BY name
     LIMIT 1)

This is correlated/ synchronous query.
