If you are studying data-related subjects, I think it would be good to set this lecture as your top priority...!!
This is a good lecture that scratches the itch of beginners or those at the elementary level, such as why to learn SQL, what the role of each grammar is, and what to do when you don't know!!

If you work with data, SQL is a fundamental skill you must know. In this course, we will learn SQL from a data analysis perspective, focusing on hands-on practice. The practice will be conducted in Google Colab using DuckDB.

SQL Basics from a Silicon Valley Data Leader

Thank you! If you have any questions, please feel free to ask. I also uploaded an Airflow lecture three weeks ago. I'm planning to upload a Spark lecture in two weeks, and I'll continue to upload lectures on search engines, recommendation engines, and A/B testing. I would appreciate your continued interest.
