Write a query to return the following fields from the Album table:
We've sorted the list alphabetically by Title.
Modify the query to return albums which didn't appear in the US Billboard 200 chart - that is, albums whose US_Billboard_200_peak position is NULL.
It's reasonable to assume that if an album doesn't appear in the weekly chart, it doesn't appear in the year end chart.
Write a query in the same script to show albums which appeared in any position the US Billboard 200 chart but which didn't appear in the US Billboard 200 year end chart.
The album should have a value for the peak chart position but no value for the year end chart position.
Write another query to return albums which had a peak chart position of 1 but which didn't appear in the year end chart.
The first few results you should see if you sort the albums alphabetically.
Write another query to return albums which reached number 1 in the weekly chart but which were outside the top 10 in the year end chart. See the image below for a hint about which results you should see.
Your list should include albums which don't have a position in the year end chart.
Remember that you can use round brackets to control the order in which your conditions are evaluated.
Save the script as Non-Charting Nulls.sql and close it.
