Transforming data means identifying relationships and patterns between the data, and making calculations based on the data you have.

The database you use contains a Tracks table. The table contains the following columns: TrackId, Name, AlbumId, MediaTypeId, GenreId, Composer, Milliseconds, Bytes, and UnitPrice. Write a SQL query to pull all columns from the Tracks table for only tracks with Chris Cornell as the composer. Sort the results in descending order by GenreId.

You Know My Name is the first value returned in the Name column when making the following query: SELECT * FROM Tracks WHERE Composer='Chris Cornell' ORDER BY GenreId DESC When executed, this query returns a list of tracks that were composed by Chris Cornell. The list would be sorted by GenreId in descending order.
