Each directory within the repository contains readme files that clarify their contents, making it easier for you to find and tackle the puzzles that interest you.

Analyzing the SQL Code

Think of SQL queries as recipes in a cookbook. Just like there are specific steps to prepare a dish, SQL involves a series of commands that operate on a database. If you were to follow a recipe without knowing the role of each ingredient, you might end up with a dish that doesn’t taste quite right.

Let’s consider a simple SQL query analogy:

SELECT Name, Age 
FROM Users 
WHERE Age > 18
ORDER BY Name;

In this analogy:

• The SELECT statement is like choosing which ingredients to use.
• The FROM clause specifies where those ingredients come from—the Users table in this case.
• WHERE filters the ingredients (or records), just like deciding to use only those that are over a certain age.
• Finally, ORDER BY organizes the finished dish, ensuring the names are served alphabetically.

By breaking down each command, you gain a clearer understanding of how SQL operates, much like mastering the art of cooking!

Troubleshooting Tips

As you work through the puzzles, you may encounter some bumps along the way. Here are a few troubleshooting ideas to help you out:

• If a puzzle isn’t running as expected, double-check your syntax to catch any typos or missing commands.
• Refer to the readme files for clues and contextual information about each puzzle.
• Join the community discussions on GitHub if you have questions; fellow SQL developers are eager to lend a helping hand!
