The instructor's English pronunciation is poor.

By Joshua Hoodin on 9/9/2026

The instructors present the information in an easy to understand way, but include lots of detail and practical tips. I am taking this course because my employer is migrating to Databricks, so it's great that Databricks is the environment used in this course. I will recommend this course to my coworkers!

By Anonymized User on 1/18/2025

This course will not only teach SQL but also help you think like a SQL engine. You will learn lots of new things. If you follow this course thoroughly, you will definitely have a greater understanding of SQL and also learn more about Darren Smith . You will know this after completing the course. One suggestion is to include the syntax of keys in a database and the concept of normalization in a separate module. This would make it a complete package with SQL and understanding some concepts of DBMS. In the future, you can add a DBMS concept module to the course and explain a few important terms that are generally asked in interviews. Overall, I enjoyed the course and the teaching style of the instructor.

This is the Best SQL course and it covers from zero to advanced level and in extreme depth sir has explained each and every concept in very layman language which even a primary school student can understand. It is totally worth it and highly recommended who want to learn SQL from scratch to advanced level.

By Anil kumar misra on 10/23/2024

I had started learning SQL when I got this cource link from Linkdin. The course is really a good one. The trainer started from sratch and went to explain everything in details. The cource content is precise and help in understanding every topic in detail. I have recommended this course to few of my friends and they have the same comments as mine. It is a very good course to learn SQL.

By Alok-k8s on 10/20/2024

It's a very detailed course and such a detail understanding is required by all data engineers, data analyst, analytics engineer, etc. This course provides lot of practical examples, discuss use cases and cover data modelling as well that's usually missed in many courses. This course gives a holistic view of SQL.

By Rajesh Koppanur on 10/20/2024

I had an excellent learning experience with the "Learn SQL for Beginners with Hands-On and Practice Exercise" course instructed by Prash Sir. The content is very well-organized, with no need to struggle with installations or data preparation as everything is provided in a structured manner, making it easy to follow. Prash Sir's teaching style, as usual, is exceptional—his explanations are clear and concise, making even complex concepts easy to grasp for beginners. One of the highlights of the course is the inclusion of a project and hands-on exercises on the Databricks platform. The "Do It Yourself" modules, available after each chapter, offer a great way to practice and apply what you’ve learned by writing SQL code. Overall, this course is a fantastic way for beginners to build a solid foundation in SQL.

By Subhabrata Nath on 10/19/2024

Prashant Sir teaches SQL exceptionally well. His explanations are clear, concise, and easy to understand, making the course accessible for both beginners and advanced users. The content is straightforward and to the point, providing a solid foundation for anyone looking to master SQL. It's a great course overall!
