RIGHT JOIN

Let's now try some RIGHT joins. A RIGHT join will return all rows from the right hand table, plus any matches from the left hand side table.

In addition to performing a RIGHT join, you'll also learn how to avoid problems when different tables have the same column names, by fully qualifying the column in your select statement. Remember, we do this by prefixing the column name with the table name.

For this exercise, we'll return to the Chinook database from earlier in the chapter.

SELECT the fully qualified column names album_id from album and name from artist. Then, join the tables so that only matching rows are returned (non-matches should be discarded).
