A focused SQL course that teaches the queries analysts write on the job: filtering, aggregation, joins, subqueries and common table expressions, and window functions. Each module has a concept lesson, a worked example on a small sales dataset, and a practice exercise with a model answer.
Eighteen written lessons across six modules. Lesson 1 is a free preview. This course does not award any certification, license or credential.
