What is the easiest way to learn SQL for data analytics?

The easiest way is Minimal Viable Analytics (MVA) — focus on 6 core operations: GROUP BY, WHERE, ORDER BY, JOIN, CASE WHEN, and charting. These cover the vast majority of real-world data analytics tasks in SQL.

How long does it take to learn SQL?

With the MVA approach, you can learn the 6 core SQL skills in about 2 hours using interactive tutorials. Each skill takes 15-30 minutes to work through.

Can I learn SQL without installing a database?

Yes. These tutorials run entirely in the browser using sql.js (SQLite compiled to WebAssembly). You can write and run real SQL queries without installing any database software.

Why SQL?

SQL is the universal language of data. Every major database — PostgreSQL, MySQL, SQLite, BigQuery, Snowflake — speaks SQL. Whether you're a data analyst, engineer, or product manager, SQL is the single most valuable data skill you can learn.

Using the Minimal Viable Analytics (MVA) approach, you focus on just 6 skills instead of trying to memorise every SQL keyword. Think of it like building a house — you need a solid foundation (your data), 6 pillars (core skills), and a roof (the decisions you make).

Decisions & Insights

Group & Aggregate

Filter

Sort

Join

Create Columns

Create Graphs

Foundation: Your Data

The 6 Pillars — SQL Tutorials

Work through each pillar in order. Every tutorial is interactive — edit the SQL and run it directly in your browser. No database installation needed.

Grouping & Aggregation

Collapse rows into categories with GROUP BY and aggregate with COUNT, SUM, AVG. Filter groups with HAVING.

Filtering

Select subsets of data with WHERE, IN, BETWEEN, LIKE, and IS NULL. Paginate with LIMIT/OFFSET.

Tutorial: How to Filter Data with SQL →

Sorting

Order results with ORDER BY, handle NULLs, and find top/bottom values with LIMIT.

Tutorial: How to Sort Data with SQL →

Joining

Combine tables with INNER JOIN, LEFT JOIN, CROSS JOIN, and the anti-join pattern.

Tutorial: How to Join Data with SQL →

Creating Columns

Derive new columns with CASE WHEN, COALESCE, ROUND, CAST, and string functions.

Creating Graphs

Query data with SQL and visualise it with Chart.js — bar, line, pie, and doughnut charts.

How to Use These Tutorials

Start with Pillar 1 (Grouping) — it introduces the dataset and core patterns
Work through Pillars 2–5 — each builds on the same fundamentals
Finish with Pillar 6 (Graphs) — bring your analysis to life visually

Each tutorial uses the same Australian petrol station dataset so concepts build naturally. By the end, you'll have the skills to tackle real data analytics problems with confidence.

Every tutorial runs in the browser using sql.js (SQLite compiled to WebAssembly). You write real SQL — the same syntax works in PostgreSQL, MySQL, BigQuery, and most other databases.

What You'll Learn

GROUP BY, COUNT(), SUM(), AVG(), HAVING — aggregate data by category
WHERE, IN, BETWEEN, LIKE, IS NULL — filter rows
ORDER BY, ASC/DESC, LIMIT — sort and find top values
INNER JOIN, LEFT JOIN, CROSS JOIN, anti-join pattern
CASE WHEN, COALESCE, ROUND, CAST — create computed columns
Chart.js — visualise SQL query results as charts
