In what situation would I use the long form syntax?

i.e using:

SELECT movies.year FROM movies;

rather than:

SELECT year FROM movies;

Once you get into JOINs you'll run into situations where you may have the same column in two different tables. A common example of this would be something like a created_at timestamp or an id. In those cases you'll need to use the long form to be explicit about what table and column you're referencing.
