“I really love learning on Dataquest. I looked into a couple of other options and I found that they were much too handhold-y and fill in the blank relative to Dataquest’s method.”
Joins in SQL allow you to combine datasets from multiple tables using a single query. In this course, you’ll learn how joins work, how to combine data from more than one table using inner joins, how to select columns from different tables, and how to alias tables.
Best of all, you’ll learn by doing — you’ll practice and get feedback directly in the browser.
