Learn and practice SELECT, JOINs, GROUP BY, Subqueries, and real-world SQL you can use from day one.

What you'll learn

⚡ Write clean SQL queries in MySQL and DBeaver to retrieve, filter, sort, and refine data using SELECT, WHERE, ORDER BY, LIMIT, and DISTINCT.
⚡ Create and safely modify relational data using data types, constraints, INSERT, UPDATE and DELETE
⚡ Turn raw rows into actionable business summaries using COUNT, SUM, AVG, MIN, MAX, GROUP BY, and HAVING.
⚡ Connect tables using primary/foreign keys, INNER JOIN, and LEFT JOIN — and read complex multi-table queries calmly, one relationship at a time.
⚡ Handle NULL values and write nested subqueries to answer business questions a single SELECT statement can't solve alone.
⚡ Build an end-to-end reporting project on realistic E-commerce and Music Shop datasets — and verify any result, even AI-generated SQL.

Requirements

❗ No prior SQL, database, or programming experience is required.
❗ You will need a computer with internet access to install MySQL and DBeaver.
❗ All software and tools used in the course are available for free.
❗ Basic computer skills and a willingness to practice with the provided datasets are all you need to get started.

Description

Do you want to actually understand SQL, not just copy-paste queries you found online, but read a database, ask it real questions, and know exactly why your query returned what it did?
Most SQL tutorials rush through basic SELECT queries and leave you stranded when you encounter real-world challenges like missing data, multi-table relationships, or complex report filtering.
This course is different. We don't just teach you syntax; we teach you how to think in sets.
Whether you are a complete beginner, an aspiring data analyst, a product manager, or an Excel user ready to level up, this course is designed to take you from zero to confidently writing complex, real-world SQL queries. No confusing academic jargon. No boring syntax memorization. Just clean, visual, step-by-step explanations paired with realistic business datasets.
If you can use a spreadsheet, you can learn SQL.

What you'll learn

✨ Set up a real database and connect to it confidently using the industry-standard DBeaver (MySQL).
✨ Read and filter data with precision: Master SELECT, WHERE, logical operators, ORDER BY, LIMIT, and DISTINCT.
✨ Summarize data like an analyst: Turn raw rows into business intelligence using COUNT, SUM, AVG, MIN, MAX, and GROUP BY.
✨ Connect related tables the right way: Understand Foreign Keys, INNER JOIN, and LEFT JOIN — and exactly when to use which.
✨ Read complex queries calmly: Learn the logical order of execution so you never panic when looking at a massive, multi-table query.
✨ Write Subqueries: Nest queries inside queries to answer advanced business questions a single SELECT can't answer alone.
✨ Manage data safely: Add, change, and remove records using INSERT, UPDATE, DELETE, and understand how to handle NULL values and Transactions.
WHY THIS COURSE IS DIFFERENT
Two Real-World Datasets: We use a running E-commerce database (Customers, Orders, OrderDetails) to teach core concepts, and a Music Shop Database for the final capstone project. Your skills will transfer to any industry.
Visual-First Explanations: Clean, clear diagrams and animations show you exactly how the database processes your data, step by step.
Active "Pause & Try" Challenges: You won't just passively watch someone else write code. Throughout the lessons, you'll encounter dedicated "Pause & Try" challenge prompts where you write the queries yourself in DBeaver before walking through the step-by-step solution together.
The "Calm Reading" Habit: We teach you a mental framework to break down any complex query one relationship at a time.
No "Gotcha" Syntax Dumps: Each idea gets the time it needs to land before the next one builds on it.
Portfolio-Ready Capstone: The final project has you build an actual multi-table reporting workflow on the Music Shop database, the exact kind of task you'd be handed in a real job.
COURSE CURRICULUM AT A GLANCE
✨ Section 1 & 2: The Foundation: Environment setup, tables, rows, columns, data types, and Primary Keys.
✨ Section 3 & 4: Querying & Managing dаta: Extracting exact data subsets with WHERE, sorting, and safely managing data changes with INSERT, UPDATE, DELETE, and Transactions.
✨ Section 5: Aggregation & Grouping: Unlocking analytical power with GROUP BY, HAVING, and aggregate functions.
✨ Section 6: Multi-Table Queries: Chaining JOINs, understanding LEFT JOIN for missing data, and mastering Subqueries.
✨ Section 7: The Capstone Project: Bringing it all together in a comprehensive, end-to-end business reporting workflow on a realistic Music Shop Database.

Who this course is for

⭐ Complete beginners who have never written a line of SQL . We assume zero prior experience and teach with clear, visual, hands-on lessons.
⭐ Excel and spreadsheet users ready to move beyond manual VLOOKUPs to a tool built for real data volume and multi-table analysis.
⭐ Aspiring data analysts and BI professionals building a practical, interview-ready foundation — including career switchers preparing for SQL-listed roles.
⭐ Marketing, product, finance, operations, and support professionals who keep having to "ask IT for a report" instead of pulling the insights themselves.
⭐ Developers, bootcamp students, and basic-SQL learners who want real confidence with JOINs, GROUP BY, subqueries, and realistic datasets.
