Looking to take your SQL skills to the next level? Our Advanced SQL Practice track offers a comprehensive set of exercises designed to help you master advanced SQL concepts and techniques. The courses in the track help you sharpen your SQL skills, with a focus on window functions and other advanced features of modern SQL. Enroll today and master advanced SQL with confidence!

These courses are specifically designed for intermediate to advanced SQL learners. Modern SQL features are used often in real-world data analysis, yet there are very few practice opportunities for learners at an advanced level. This track is designed to address this need.

Gain hands-on experience using GROUP BY and CASE to build complex reports. Take advantage of the many exercises for using date and time functions, designing and managing complex queries, and much more. Immerse yourself in SQL window functions practice exercises. Practice using CTEs (Common Table Expressions) and explore the power of recursive SQL queries.

To get the most from this track, a solid foundation in the SQL topics listed above is recommended. If you're not yet familiar with them, don't worry! We've got you covered with these advanced SQL courses: Creating Basic SQL Reports, Window Functions, Recursive Queries, and GROUP BY Extensions. Then, come back here for more advanced SQL exercises with solutions.

Experience interactive SQL learning like never before! Each course offers a unique set of challenges designed to help you master advanced SQL concepts. All exercises are based on real-world scenarios that require you to write SQL code to solve problems. Our platform provides instant feedback, verifying your code and helping you learn from mistakes.

Whether you're a beginner or an experienced data analyst, we have designed our courses to help you get valuable SQL practice. By the end of the track, not only will you have refined your skills and expanded your knowledge, but also you will have gained the confidence needed to tackle any data analytics project with ease.

The courses in this track are designed to provide a realistic setting for practicing advanced SQL features in a way that mirrors professional data analysis. Analyze customer behavior and purchase patterns with a dataset from a fictional online store. Rank the best-selling products using GROUP BY and ranking window functions. Create rankings in custom categories using CASE and GROUP BY. Generate reports that compare monthly sales using the window functions LEAD() and LAG(). Find the running total of the sales for the current month using date functions and OVER().

How about mining the website traffic data for a fictional pet store? Identify popular blog articles and understand traffic on the website. Find article views for each author by month using GROUP BY and date functions. Compare article views between a given month to the preceding month using window functions. Rank the most popular articles within each category and identify the most efficient articles for each product category using CTEs.

Even a family tree dataset. Extract information such as the number of ancestors or siblings for each person using recursive SQL queries.

These are just a few examples of what is in store. The courses in this track have many other real-world datasets for you to practice advanced SQL features.

Enrolling in the Advanced SQL Practice track is a smart choice for data analysts looking to improve their skills and stay ahead of the competition. Don't miss out on this opportunity to hone your SQL skills and become a more efficient and effective data analyst. Sign up now and take your SQL knowledge to the next level.
