SQL Lesson X To infinity and beyond!

We hope the lessons have given you a bit more experience with SQL and a bit more confidence to use SQL with your own data.
We've just brushed the surface of what SQL is capable of, so to get a better idea of how SQL can be used in the real world, we'll be adding more articles in theĀ More TopicsĀ part of the site. If you have the time, we recommend that you continue to dive deeper into SQL!
If you need further details, it's also recommended that you read the documentation for the specific database that you are using, especially since each database has its own set of features and optimizations.
If you have any suggestions on how to make the site better, you can get in touch using one of the links in the footer below.

The current webpage is the completion page for SQLBolt's interactive SQL tutorial. It congratulates you on finishing the course and encourages further learning, noting that the lessons have only covered the basics of SQL. The page recommends exploring additional articles in the "More Topics" section for deeper knowledge, as well as reading official database documentation since features and optimizations vary by system.
It also invites users to provide feedback to improve the site and suggests donating $4 via PayPal to help support and expand the platform. Finally, it provides links to social sharing options and mentions an additional course on regular expressions.
Intermediate SQL Topics
Before we get started, if you haven't yet completed ourĀ Interactive TutorialĀ or still don't feel comfortable with SQL, please complete that before continuing. The following deep-dive topics will be building on the foundation from the lessons in the tutorial by exploring more advanced SQL constructs that you might find useful when dealing with real-world data.
The current webpage, "SQLBolt - Learn SQL - Intermediate SQL Topics," is a resource for learning more advanced SQL concepts beyond the basics. It recommends users first complete the introductory interactive tutorial before proceeding. The page covers intermediate SQL topics such as:
- Subqueries
- Set operations
It also mentions that upcoming topics will include Foreign Keys, Dates and Times, Views, and more. The site focuses on clear explanations and interactive exercises designed to help users apply SQL in real-world scenarios.
