MySQL exercise

Oops! This was supposed to have gone into the class blog but I put in here by mistake. Still, since it's already here, I might as well keep it here.

From the MySQL downloads site the following files:

* world.sql.zip
* world-setup-en.pdf

world.sql.zip is a sample database containing data about countries of the world, their cities, and the languages spoken in each. world-setup-en.pdf contains the setup instructions.

Using your knowledge of SQL, determine the following information:

* What is the country code of the Philippines? Of Argentina? Of Nepal?
* What are the cities of the Philippines? Of New Zealand? Of Afghanistan?
* What country has the largest population? What country has the smallest population?
* Which countries speak German as their official language?
* What is the most populous city and which country is it located in?
* What is the most populous capital city? What is the least populous capital city?

Do some other queries. Make use of SQL joins to execute more complex queries.
