SQL Fiddle Exercise 4 - Date Filter

Write a query that only returns sales made in the second half of the current month. In the model we provided that can be the year 2020 or 2021 or even both!

For transactions in June, there are 2 sales made in the second half of the month in 2021.

Expanding the clause to include both 2020 and 2021 will be a little bit harder.

This data has been ordered, but it's for you to work out how!

Keep in mind that when working with dates using the reverse format yyyy-mm-dd is usually the safest method.

Check out the answer here.
