Become an SQL Expert: From Basics to Advanced Techniques

Dive into the world of SQL with this comprehensive course designed for both beginners and advanced learners. Starting from the basics, you’ll learn to execute fundamental queries, filter data, and use powerful aggregate functions like COUNT(), SUM(), AVG(), and GROUP BY. We’ll gradually explore complex relationships between tables with various JOIN types including INNER, LEFT, RIGHT, FULL, CROSS, and Self Joins. By the end of this section, you’ll be crafting robust queries with confidence.

Taking it a step further, you’ll master subqueries and work with Common Table Expressions (CTEs) and recursive CTEs to effectively structure complex queries. Explore the power of window functions such as ROW_NUMBER(), RANK(), LEAD(), and LAG() for advanced data analysis. Additionally, we’ll cover essential functions for dealing with text, math, and dates to enhance your query capabilities. You’ll also gain insights into query optimization where you’ll learn to employ EXPLAIN and ANALYZE, interpret execution plans, and improve performance with indexing strategies.

By the end of this course, you’ll confidently tackle complex data tasks in professional environments. Not only will you have an in-depth understanding of SQL, but you’ll also be ready to face real-world challenges. Enroll now and elevate your SQL skills to a professional level!
