Intro to SQL

Learn the core building blocks of SQL by writing real queries against real data. You’ll cover everything from SELECT statements and filtering with WHERE, to sorting, grouping, and basic data manipulation with INSERT, UPDATE, and DELETE.

Go beyond single-table queries and learn how to work with relational data. This module covers creating and modifying tables, populating them with data, and using different types of joins to combine data across tables.

In this module, you’ll learn how to use ANY, ALL, and EXISTS for powerful subqueries, and apply CASE expressions in SELECT, WHERE, and UPDATE clauses to create dynamic, flexible queries.
