Welcome to the Weekly SQL Quiz
Welcome to the weekly SQL quiz of the PL/SQL Challenge. Our objective is to give you a regular opportunity to test, demonstrate, and improve your knowledge of the Oracle SQL language. The quiz questions cover a wide variety of the features of SQL, much of it ANSI-standard SQL, but also specific extensions to SQL implemented by Oracle.
Some of the questions test your knowledge of syntax, others explore the way that certain features of SQL can be applied to solve problems. Some questions will seem easy to you, some hard, but over time the weekly quiz should do a good job of not only demonstrating just how familiar you are with SQL, but also deepen your understanding of the language.
To play the quiz, you must first register at the PL/SQL Challenge, host of the Weekly SQL Quiz. If you have previously registered, press Login and Play. Otherwise, press Register to Play.
