The explanation is clear.

Even those who have just learned SQL for the first time can understand everything without any problems if they move on to the intermediate class after taking the basic class.

It was very helpful because you focused on the strategies and direction for preparing for a career in data analysis. Some of the speakers' advice hit home quite hard, while other parts gave me great courage. I am truly grateful to the speakers and the Datarian team for creating this video.

It's very easy!

It was very helpful because you explained Joins and Unions, the highlights of the basic lecture, so well.

It's a decent introductory course, but it feels like the short, entry-level content has been broken down into too many small segments.

The instructor explains things well, but I still don't quite understand the subquery logic.

It was a great course for applying various SQL syntaxes to real-world practice.

Thank you for sharing your DB/SQL coding test experience.

It was an easy-to-understand lecture. I haven't fully mastered everything yet, so I will review it several more times.
