Activity Overview As data calculations become more complicated, there are many components to keep track of, such as range, cost, time elements, products, and more. Some people use sticky notes for this, while others use checklists. In the data profession, a temporary table is just like a sticky note. You learned about temporary tables in SQL in earlier lessons, so take a moment to review. Temporary tables, or temp tables, store subsets of data from standard data tables for a certain period of time. Temp tables allow you to run calculations in temporary data tables without needing to make modifications to the primary tables in your database. Because they are temporary, they are automatically deleted at the end of your SQL session. By the end of this activity, you will have gained more experience creating temp tables and using them to run queries. Review the following scenario. Then complete the step-by-step instructions.

Solution

To find the least frequent starting station of the bike ridden for the most time, you would need to change the query in the second occurrence of ORDER BY to sort by trip count in ascending order. This will give you the bike that has the least number of trips. The correct code revision would be:

-- In the second occurrence of ORDER BY:
ORDER BY
    trip_ct ASC

This will sort the results in ascending order by the count of trips, effectively giving you the least frequent starting station of the bike ridden for the most time.
