Our take
A hands-on, interactive way to learn SQL through in-browser exercises, with immediate practice as you go. Access is via a DataCamp subscription.

Good for: beginners who want to learn SQL through interactive, hands-on practice.

Skip if: you already know SQL, or you prefer video lectures over exercises.

The five-course track builds from basic SELECT queries through joins, aggregations, subqueries, CTEs and window functions, plus a little database design, all on real datasets with no local setup. The practice-first format is its strength for verifying you can actually write SQL.

What it does not do is teach through video lectures, and it will not suit someone who already knows SQL — a project or reference approach fits better instead. It needs a subscription; the SQL it teaches is stable and still relevant, and DataCamp keeps the track updated.

About this course

DataCamp's SQL Fundamentals track teaches SQL from basic SELECT queries through intermediate and advanced SQL: joins, aggregations, subqueries, CTEs, window functions (ROW_NUMBER, LAG/LEAD, RANK), and introduction to database design. All five courses use an interactive browser-based SQL environment with real datasets — no setup required.

Frequently asked questions

It is a browser-based platform built around short video lessons followed immediately by hands-on coding exercises — you write real SQL in the browser and get instant feedback, with no setup required. This 'track' bundles several SQL courses into an ordered path. It runs on a subscription, though the first chapter of every course is free and there is usually a free trial of the full platform.

Yes, it is designed as an entry point with no prior SQL assumed. It starts from how relational databases are structured and basic queries, then builds toward summarising data, joining tables, and using window functions. The interactive, do-it-as-you-learn format suits beginners well, since you practise each concept immediately rather than only watching someone else write queries.

Core SQL for working with data: structuring and querying relational databases, filtering and summarising results, joining multiple tables, and using window functions and built-in PostgreSQL functions to analyse data. It is taught in PostgreSQL, but the fundamentals transfer cleanly to other databases like MySQL or SQL Server, with only minor syntax differences to adjust to later.

Partly. DataCamp's free tier gives you the first chapter of every course, and there is a week-long full-access free trial, but completing the whole track requires a Premium subscription (around 25 US dollars a month). So you can sample it and even blitz a lot during a free week, but finishing the full track properly is a paid experience.

The track runs around 26 hours, self-paced, so most people spread it over a few weeks. For interactive, low-friction SQL practice with instant feedback, it is a strong way to build genuine fluency — arguably its biggest strength over video-only courses. Just treat the subscription cost accordingly, and know that job-readiness also means practising on messy real datasets beyond the tidy exercises here.
