Whatever you pick up will be immediately applicable to your job. To do that, you need to understand how your company's data is organized. Where's the product and marketing data stored?

I took a SQL course online but it was very generic, and there were no challenging problems to solve. This is exactly what I needed to get some more practice with SQL. I skipped the introductory problems. I went right into the intermediate problems.
Tried not to use the hints, but ended up using them a few times. The answers and explanations are concise, and get right to the point.
Very practical. I have a lot more confidence writing SQL at work now. Alas, knowing the material is not the same as being able to present it clearly and in digestible bites. Obviously, you have that knack. I have learned things from your book that nobody ever showed me before. I sincerely hope that you will write more books. Step-by- step video to walk you through practice database setup.
Hi, my name is Sylvia Moestl Vasilik. I've been a senior data engineer, architect and database programmer for more than 15 years, working at top organizations like Expedia, Microsoft, T-Mobile, and the Gates Foundation.
I write on database topics on my DatabasesAreFun blog. They learned the basics of SQL, most of the keywords, and worked through practice problems every week.
Yes, the students learned a lot about SQL. However, they spent a tremendous amount of money, and many hours every week, working through a dry manual, instead of solving real world data problems. I'd like to work on more complex data problems. Where can I find them? But where can I find more advanced data problems, that teach me real-world SQL?
Problems that will help people get the experience they need, for the jobs they want, packaged in an easy-to-follow, "learn-by-doing" format. Watching other people explain concepts on videos is fine for a shallow, introductory understanding. But you won't be able to solve problems. Videos will not give you the hands-on experience that you need. For that, you need well-designed practice problems that teach data-oriented thinking through actual doing.
Working through well-designed problems is the gold standard for learning. This volume does exactly what it describes--provide practical and challenging problems to solve in SQL Server.
Many readers have emailed me, and said that they paid hundreds and even thousands of dollars for other educational materials that promised to teach SQL, that were—and this is a direct quote—"useless". These materials were frequently just a reformatted version of the online documentation. Or they were extremely wordy, forcing them go through pages and pages of text to find anything useful. They finally succeeded in learning SQL by working through these practice problems, step-by-step.
