Take Control: Q&A
Queries ask questions:“Who bought what?”
Think of all those records in the tables.
In the Front Row Video
database, your query could ask, “How many of these movies are 1-day
rentals? How many are 3-day rentals?"
Video rental prices are usually based on the year
that a movie was released. There is a premium price for new
releases. Older movies can be rented for much less. Let’s find out
which movies are new releases and which ones are older.
