🪑 Limited seats — it's an in-person, hands-on session.
Workshop starts 10 November at 11 AM IST
Does this sound like you?
If you nod to even one of these, this workshop was made for you.
- 😩 You've watched SQL videos, but freeze when you have to write a query yourself.
- 🎤 Interviewers ask "How will you find…?" and you don't know where to start.
- 🧩 GROUP BY, HAVING and JOINs still feel confusing.
- 🧹 You don't know how to handle NULLs, duplicates and messy data.
- 🎯 You want a Data Analyst role, but SQL is the skill holding you back.
In just 3 hands-on hours, you'll write the queries interviewers actually ask for — on a real dataset.
Real Interview Questions You'll Solve
Here are two of them. In the workshop we solve many more like these — step by step, on your own system.
You are given a Sales table. How will you find the product that generated the highest revenue?
① Sales Data (Sample)
| OrderID | Product | Qty | Revenue |
|---|---|---|---|
| 101 | Laptop | 2 | ₹90,000 |
| 102 | Mobile | 5 | ₹75,000 |
| 103 | Laptop | 1 | ₹45,000 |
| 104 | Headset | 10 | ₹20,000 |
| 105 | Mobile | 3 | ₹45,000 |
② SQL Query (GROUP BY)
SELECT Product, SUM(Revenue) AS Total_Revenue FROM Sales GROUP BY Product ORDER BY Total_Revenue DESC;
③ Result
| Product | Total_Revenue |
|---|---|
| 🥇 Laptop | ₹1,35,000 |
| Mobile | ₹1,20,000 |
| Headset | ₹20,000 |
💡 Business insight: Laptop is the highest revenue-generating product.
A customer table contains NULL values in the Email column. How will you identify and clean them?
① Before (NULL values)
| ID | Name | |
|---|---|---|
| 1 | Arun | arun@gmail.com |
| 2 | Priya | NULL |
| 3 | Kavin | kavin@gmail.com |
| 4 | Divya | NULL |
② Find & clean
SELECT * FROM Customers WHERE Email IS NULL; UPDATE Customers SET Email = 'Not Provided' WHERE Email IS NULL;
③ After (cleaned)
| ID | Name | |
|---|---|---|
| 1 | Arun | arun@gmail.com |
| 2 | Priya | Not Provided |
| 3 | Kavin | kavin@gmail.com |
| 4 | Divya | Not Provided |
