Sort Results Part 1

Part of the Fundamentals section of Coddy's SQL journey — lesson 13 of 72.

When querying a database, organizing your results in a meaningful order can make data analysis much more efficient. To sort the result we use the ORDER BY keyword and after that, we should specify by which field we are ordering by. By default, it sorts by ascending order.

For example consider the following competition table:

runner_id	age	avg_speed
1	47	3.65
2	62	3.07
3	57	6.82
4	56	4.34
5	25	4.93
6	40	3.94
7	23	6.58
8	40	3.43

SELECT *
FROM competition
WHERE age > 50
ORDER BY avg_speed

This is the result

runner_id	age	avg_speed
2	62	3.07
4	56	4.34
3	57	6.82

To specify how to sort that data we can add DESC or ASC keywords after the name of the column.

ORDER BY avg_speed ASC

Challenge

Easy

Available tables and columns:
feathers: id, weight

Return all of the ids after ordering them by the weight in descending order
