Read a database before you query it
Tables, keys, relationships and normalisation — so you know what you're looking at instead of guessing which column joins to what.
Free learning initiative
A free SQL crash course, built for how analysts actually work
SQL is the language behind almost every analyst, data and product role. Jobaaj Learnings is making this crash course free for every student — from your first SELECT through joins, window functions and CTEs, at whatever pace suits you.
No payment step. Start the first lesson straight away.

What you'll learn
From your first query to the ones that get asked in interviews
SQL rewards people who can think in sets, not people who memorise syntax. This crash course is built around the six things that actually come up in analyst work.
Filter data with real precision
SELECT, WHERE, IN, BETWEEN, LIKE and NULL handling — the clauses you'll use in ninety percent of the queries you ever write.
Join tables without losing rows
Inner, left, right and full joins, plus UNION — and, more importantly, how to spot when a join has silently dropped or duplicated your data.
Aggregate the way reports need it
GROUP BY, HAVING and the aggregate functions behind every dashboard metric — including where WHERE stops working and HAVING takes over.
Write queries that stay readable
Subqueries, CTEs, recursive CTEs and window functions — how to break a difficult question into steps someone else can follow six months later.
Understand what production expects
Views, stored procedures, triggers and indexing — the parts that separate someone who can query from someone a team can hand a database to.
Why it's free
We built this to be learned from, not sold.
A lot of people who need a skill like this are exactly the people least able to pay for it — students between semesters, freshers before a first job, anyone rebuilding after a break. So we took the fee off.
01
The whole course, not a preview
Every lesson is open from the start. There's no locked second half and no upgrade waiting three modules in.
02
Free because it should be, not for a window
This isn't a promotional price or a trial. There's no clock on it and no fee arriving later.
03
Built to the same standard as the rest
Nothing was trimmed to make it free. It is the same material, at the same depth, as everything else we teach.
04
Yours to keep
Come back to a lesson next month or next year. Access doesn't expire and nothing gets pulled behind a paywall.
Where it takes you
One query language, a lot of doors
SQL sits underneath analytics, product, consulting and engineering work alike. These are the roles it most often opens up.
Data Analyst
Pull business data, build dashboards and turn a messy question into a number someone can act on.
Business Analyst
Sit between the business and the data, and answer the questions that decide where budget goes.
Product Analyst
Track how people actually use a product — funnels, retention, feature adoption — straight from the event tables.
Product Manager
Check your own assumptions before a roadmap meeting instead of waiting a week for someone to run the query.
Data Engineer
Build and maintain the pipelines and warehouses everyone else's dashboards quietly depend on.
Software Engineer
Design application schemas, write the queries behind features, and fix the slow ones before users notice.

Questions people ask before starting
Yes. Jobaaj Learnings provides it free of cost. There’s no fee to start, no trial period that ends, and no payment step anywhere in the flow.
None. The course starts from the very beginning and builds up from there, so you can begin with no prior experience in the subject.
Yes. Every lesson is recorded, so you can pause, rewind and come back whenever it fits around classes or work. There’s no schedule to keep up with.
Standard SQL covers most of what you’ll write, and the concepts move across MySQL, PostgreSQL and SQL Server largely unchanged. Any free local install or browser-based SQL sandbox works for following along.
Write queries that filter, join and aggregate data; use subqueries, window functions and CTEs; and read a database schema well enough to work out how the tables fit together on your own.
