Learn Intermediate SQL

In this intermediate SQL course, you’ll explore Structured Query Language (SQL) through hands-on, project-based lessons. You’ll start with core SQL queries such as SELECT, WHERE, AND, OR, NOT, and string handling, then progress to DISTINCT, ORDER BY, GROUP BY, and aggregate functions. You’ll learn to create, describe, insert into, update, delete, and alter tables, use aliases, and minimize data redundancy with foreign keys. Finally, you’ll master joins, subqueries, and cartesian products to extract and manipulate data across multiple tables and generate comprehensive reports.
