Course overview

This course takes you from zero SQL knowledge to writing confident queries. You'll start by understanding what databases are and how SQL fits in, then progressively learn to create tables, insert and manipulate data, filter and sort results, combine data from multiple tables with JOINs, and perform calculations with aggregate and scalar functions.

Every chapter includes real SQL code examples with actual query results, practical explanations, and key takeaways. By the end, you'll be able to design simple databases, write complex queries, and understand the fundamentals that every SQL professional uses daily.

After completing this course, continue with the SQL Intermediate Course to learn views, stored procedures, normalization, and advanced querying techniques.
