Carmen San Diego Lab

Introduction

Use SQL to find Carmen Sandiego

We're going to use what we've learned already about querying a database using SQL commands to to chase down and capture an elusive and world-renowned thief, Carmen Sandiego!

Set Up

Download the starter files
Extract the folder from the .zip file and open in VS Code: $ code .
Open a terminal session and run ls. Ensure that you see the files: clues.sql & world.sql.
Start the psql interactive terminal: $ psql
Create a database named carmen and connect to it:
```
CREATE DATABASE carmen;
\c carmen
```
Create city, country & countrylanguage tables and seed their data using the import (\i) psql command:
```
\i world.sql
```

Exercise

The goal is to figure out what city Carmen Sandiego is heading to so that she can be met by the proper authorities.

You'll be writing SQL queries within clues.sql to answer each clue.

Run the queries in psql by typing \i clues.sql.

Hints

Use the psql \d & \dt tablename commands to list & display the schema of each of the three tables.
Google and collaborate to reach the goal of finding out where Carmen's destination is.
For example, you'll certainly need to know about the ORDER BY. clause.
