Timeline for the Day
Sunday, February 8th • Live on Zoom
Getting Started
We begin by laying the foundation. You'll understand what SQL is used for, how relational databases work, and how to think in tables, rows, and columns.
- ✓What is SQL and where it is used
- ✓Relational database concepts
- ✓Tables, rows, and columns
SQL Fundamentals
This session focuses on the core building blocks of SQL. You'll start writing real queries and understanding how data is retrieved and filtered.
Inbuilt Functions & Constraints
Learn how to work with SQL's inbuilt functions and understand constraints that ensure data accuracy and integrity.
- ✓Common inbuilt functions
- ✓NOT NULL, UNIQUE, PRIMARY KEY
- ✓Basic data validation concepts
Break
Take a breather, grab lunch, and recharge for the advanced sections. (60 mins)
Joins & Subqueries
This is where SQL becomes powerful. You'll learn how to combine data across tables and write nested queries to answer complex questions.
- ✓INNER JOIN and LEFT JOIN
- ✓Understanding relationships between tables
- ✓Introduction to subqueries
Advanced Aggregation
We close the core learning with advanced aggregation techniques used heavily in analytics and data science workflows.
- ✓COUNT, SUM, AVG
- ✓GROUP BY and HAVING
- ✓Real-world aggregation examples
Why Learn SQL?
Data is the new oil. In this 6-hour power session, you will gain the skills to extract insights from raw data.
Database Fundamentals
Understand how relational databases work, what
tables are, and how data is structured for modern
applications.
Writing Queries
Learn the SELECT statement inside out. Filter, sort,
and manipulate data to answer real business
questions.
Data Analysis
Move beyond basic retrieval. Use aggregate
functions and joins to combine data sets for
powerful reporting.

What Students Say
“I never thought I could understand databases in just one day. The 6-hour format was intense but the breaks were well-timed. Highly recommend for any beginner.”
David Chen
Marketing Analyst
“The 42Peaks team knows how to teach. The "Free for New Year" offer was too good to pass up, and the value delivered was worth way more than the original price.”

Frequently Asked Questions
Is this webinar really free?
Yes. There's no cost to attend, no hidden conditions, and no obligation afterward. You register, join the session, learn, and that's it.
Why is this free?
Because this is how we believe learning should be.
42Peaks was built by people who learned the hard way: through scattered resources, trial and error, and unnecessary gatekeeping. Shreyansh, the founder of 42Peaks, is a self-taught engineer and strongly believes in non-salesy, hands-on, democratic access to quality education. This webinar is our way of offering the kind of learning experience we wish we had when we were starting out.
Who is this webinar for?
This webinar is for students and early professionals targeting Data Analyst, Data Science, BI, or analytics-heavy roles who want to build strong SQL fundamentals and understand how SQL is actually used in practice.
What will I be able to do by the end of the session?
By the end of the webinar, you'll be able to write practical SQL queries for analytics use cases-filtering data, aggregating results, applying constraints, working with joins and subqueries, and thinking clearly about data extraction problems.
Is this beginner-friendly, or is it meant for people who already know SQL?
It's designed to start from the basics and gradually move into more advanced concepts. Beginners can follow comfortably, and people with some prior exposure to SQL will benefit from the later sections on joins, subqueries, and advanced aggregations.
Is this theoretical, or will we actually practice?
This is a hands-on session. You'll write and run queries live during the webinar, following practical examples rather than just watching slides.
What if I haven't set up SQL before the webinar?
That's completely fine. We have a dedicated setup section during the webinar where we'll walk everyone through installing and configuring SQL step by step. No advance preparation is required.
Which database and tools will we use?
We'll use Microsoft SQL Server (MSSQL) installed locally on your system, typically with SQL Server Management Studio (SSMS) for writing and executing queries.
Will this work on my operating system?
MSSQL works best on Windows. macOS and Linux users can still participate, though they may need additional setup steps, which we'll cover during the setup section.
What if I get stuck or miss something during the session?
You'll receive the full recording after the webinar, so you can revisit any part at your own pace. Questions can be asked during the session, and we'll address common issues live.
