PL/SQL Challenge - Test your PL/SQL knowledge   Two ways to play:  The monthly Toad World quiz  and the daily challenge. You don't have to play the daily quiz to play the ToadWorld quiz, but you are certainly welcome to do so. And if you answer the ToadWorld quiz correctly you may be selected to win one of four handsome ToadWorld t-shirts.   The PL/SQL Challenge is simple: you play the quiz - daily. We keep score. You get ranked. Every three months, the top-ranking players compete in a quarterly championship to award first, second and third prizes. But that's not all! Every month, we will raffle off other prizes to anyone who played the quiz that month. And the more you play, the greater your chance of winning.   >TAKE THE CHALLENGE
