Hello Devs, I am feeling proud and excited to share the news with you all that my new book, [**"Grokking the SQL Interview"**](https://javinpaul.gumroad.com/l/grokking-the-sql-interview)**, which I announced 2 years back is now released.

## Why you need a book on SQL Interview Questions?
SQL (Structured Query Language) is a fundamental skill for roles spanning Quality Assurance, Business Analysis, Data Science, Programming, Database Administration, and more.  That's why you will always find SQL related questions like how index work? difference between index seek and index scan during tech interviews.

While a SQL primer book is good for learning SQL commands they generally not cover the type of concepts asked on interviews. A specialized book like **['Grokking the SQL Interview'](https://bit.ly/3OWnYuD)** serves as a valuable resource to bridge the gap between theoretical knowledge and practical interview scenarios.

This book addresses the unique challenges candidates face during SQL interviews by presenting a curated collection of frequently asked questions. It goes beyond rote memorization, offering in-depth explanations and insights into essential SQL topics.

I have included many popular SQL questions like difference between WHERE and HAVING clause, difference between UNION and UNION ALL, and ROW_NUMBER vs RANK vs DEEP_RANK() in this book. It even contains deep dive into popular questions where you will learn in-depth like shown below:
