Sorting by Multiple Columns
We can also sort by several columns. We need to specify the column names separated by commas. Let’s look at the example that retrieves three columns and sorts the results by two of them - first by population and then by capital.
1234SELECT ID, population, capital FROM country ORDER BY population, capital;

Retrieve four columns using the SELECT statement, namely: continent, region, population, and capital (please retrieve these columns in this order). Then, sort the result by two of them - first by continent, then by population.
