Learn SQL

Scrimba's free beginner course on SQL, taught by Gregor Thomson across roughly 3.8 hours. It takes the core database query language from first principles up to joins and conditional logic.

Quick answer​

Learn SQL is Scrimba's free, beginner-level SQL course: about 3.8 hours across three modules and 50 lessons, taught by Gregor Thomson. You start with basic queries, move to creating and joining tables, and finish with more advanced logic and conditions. It assumes no prior programming and works well as a first database course, making it a natural backend anchor.

Is it worth your time?​

It is free, it assumes nothing, and SQL is one of the most durable skills in software. The language barely changes year to year, so the hours you put in here keep paying off across data work, backend development, and analytics. As a first database course it is hard to fault on value.

The honest caveat is that SQL has a long tail this course does not reach. You learn enough to query and join confidently, but production topics like indexing strategy, query performance tuning, transactions, and database design beyond the basics live outside the 3.8 hours. That is appropriate for a beginner anchor; just know it is a starting point, not the whole subject.

What you'll learn​

Course curriculum

3 modules

  1. Fundamentals of SQL92 min
  2. Creating and Joining Tables68 min
  3. Advanced Logic and Conditions45 min

The progression is sensible. Fundamentals is the largest block and covers selecting, filtering, and shaping result sets. Creating and Joining Tables is where SQL becomes powerful, since most real questions span more than one table. Advanced Logic and Conditions adds the conditional and grouping tools that turn raw queries into answers. By the end you can read and write the queries most applications actually run.

Who it's for, and who should skip it​

It fits complete beginners who want a first real grounding in databases, and frontend or full-stack learners who can already build interfaces but freeze the moment data needs querying. No prior code is required.

Skip it if you already write SQL comfortably and want depth on performance, indexing, or schema design, since this stays at the fundamentals. Those topics are better served by a database-specific resource after this.

Prerequisites​

None. The course is built for beginners and assumes no programming background. A browser and willingness to type queries are enough.

Where it fits​

Learn SQL sits on both the Backend Developer Path and the Fullstack Developer Path as the database foundation. It pairs naturally with Intro to Supabase, which puts a Postgres database behind a real app once you understand the query language underneath it.

Free or Pro​

The course itself is free, with no subscription required to start or finish it. Scrimba Pro is a separate decision that unlocks the structured career paths, the coding challenges, the private Discord, and certificates. For this course alone you never have to pay.

Strengths and limits​

What it does well: it is free, it assumes nothing, it teaches a skill that ages well, and the interactive format lets you run queries as you learn rather than just reading them.

Where it is limited: it stops at the fundamentals, so it does not cover performance tuning, indexing, transactions, or deeper schema design. For those you graduate to a database-specific course after this one.
