SQL PUZZLES is scheduled to go out of print. Sales wer nto good enough
for a second edition. I think you can still get from www.MKP.com
directly or as  used book on Amazon.com.

It is a good book for students to have because so many professors have
been stealing homework assignments from it for years.  Then the
students, not knowing the source, email to me for an answer.  So, not
only are they asking me to condone
cheating on their homework, but I lose the royalty money.  I am not
kidding.
