If you’re preparing for a SQL or data-focused interview, you’re likely to face more than just basic syntax questions. Employers want to see how well you can apply SQL to real-world data problems. That’s where SQL scenario-based interview questions come in.
In this guide, we’ll walk through top SQL scenarios you might encounter in interviews, complete with answers and explanations.
🚀 Why SQL Scenario-Based Questions Matter
While theoretical SQL knowledge is great, employers are more interested in how you:
- Handle business logic
- Solve data analysis problems
- Optimize query performance
- Work with complex datasets
Scenario-based questions test your real-world SQL problem-solving skills and show how you think through challenges. That’s why they’re commonly used in interviews for roles like:
- Data Analyst
- Business Analyst
- Data Engineer
- Backend Developer
📊 Sample Database Used
For the following scenarios, we’ll use two simple tables:
Orders
| order_id | customer_id | order_date | amount |
|---|---|---|---|
| 1 | 101 | 2023-01-15 | 500 |
| 2 | 102 | 2023-01-20 | 300 |
| 3 | 101 | 2023-02-02 | 450 |
| 4 | 103 | 2023-02-10 | 700 |
| 5 | 101 | 2023-02-22 | 200 |
Customers
| customer_id | customer_name |
|---|---|
| 101 | Alice |
| 102 | Bob |
| 103 | Carol |
🔥 Top 10 SQL Scenario-Based Interview Questions
1. Find the first order placed by each customer.
SELECT * FROM Orders o
WHERE order_date = (
SELECT MIN(order_date)
FROM Orders o2
WHERE o.customer_id = o2.customer_id
);
2. Retrieve customers who have placed more than one order.
SELECT customer_id, COUNT(*) AS order_count
FROM Orders
GROUP BY customer_id
HAVING COUNT(*) > 1;
3. Get total amount spent by each customer.
SELECT c.customer_name, SUM(o.amount) AS total_spent
FROM Orders o
JOIN Customers c ON o.customer_id = c.customer_id
GROUP BY c.customer_name;
4. List customers who haven’t placed any orders.
SELECT c.customer_name
FROM Customers c
LEFT JOIN Orders o ON c.customer_id = o.customer_id
WHERE o.order_id IS NULL;
5. Find customers with the highest single order amount.
SELECT customer_id, amount
FROM Orders
WHERE amount = (
SELECT MAX(amount) FROM Orders
);
6. Show customer order count and average order value.
SELECT customer_id, COUNT(*) AS total_orders, AVG(amount) AS avg_value
FROM Orders
GROUP BY customer_id;
7. Fetch the top 2 customers who spent the most.
SELECT customer_id, SUM(amount) AS total_spent
FROM Orders
GROUP BY customer_id
ORDER BY total_spent DESC
LIMIT 2;
8. List all orders with customer names.
SELECT o.order_id, c.customer_name, o.amount
FROM Orders o
JOIN Customers c ON o.customer_id = c.customer_id;
9. Find customers who placed an order in February 2023.
SELECT DISTINCT c.customer_name
FROM Orders o
JOIN Customers c ON o.customer_id = c.customer_id
WHERE o.order_date BETWEEN '2023-02-01' AND '2023-02-28';
10. Identify repeat customers (ordered more than once) with total spent.
SELECT customer_id, COUNT(order_id) AS orders, SUM(amount) AS total_spent
FROM Orders
GROUP BY customer_id
HAVING COUNT(order_id) > 1;
