Exercise #6

Due:  This exercise is for your review only, and is not to be handed in.  I will try to get an exercise key published (on the course home page) some time on the weekend of April 23

Please work (in SQL) problems 27, 28, 29, 30, 39 on pages 208 - 209 of Date. As you did with the previous SQL exercises, please place the exercises in a .sql file with the following documentation:

Each query should be run (i.e., use semicolons after each SQL statement). Please be aware that not all of these queries will result in any rows being produced.
