The Advanced SQL Course (Udemy.com)

It is useful and explanation is very clear. overall its good to cover advance topics. very nice Explained with examples , great course. Thank you.

The course is quite good with simple explanations along with examples and small assignments in between. Small assignment in contrast to larger ones brings motivation in learning

I had used Oracle DB very long time ago. I am trying to come back and refresh skills. I never knew Oracle had provided facility to learn on cloud. I really liked the course and see what all going to unfold as I progress ! Thanks to Tutor!!

This course is amazing, and I have gone through this course couple of times to crack the "Data Engineer" technical interview. This course along with the DBT course was very helpful for the interview prep and enabled me to clear few job interviews. Thanks a lot!!

I think I feel its a bit monotonous which makes it harder to focus. I recently took another SQL course which was a lot more easy to follow as the instructor structured it in a lot more interesting format and delivery was engaging. Content of the course is no doubt valuable and informative.

Excellent teaching - thank you - I will be reviewing these lessons at least one more time. I actually can apply this knowledge right at work as I am building a complicated report and did not know how I was going to get it done. I have a better way now.

It was a great course overall I just have some points for improvement * The regex section could be removed or shrunk since is not related only to SQL. * Like the idea of using the same dataset for different functions, In this way you can compare results and understand better what the functions do. * When removing things you could just trim the part you write the query.

This course was exactly what I was looking for! It doesn't waste time reviewing beginner concepts like many other courses do. Quick short videos that get right to the point and show more advance SQL skills. The only critique I would have is that I wish it had more examples when going over Common table Expressions (CTEs).

I think that in terms of advanced functions the course covers a great deal of that material with examples and clear explanations. The only draw back of this course is the fact that it doesn't tackle real life professional business questions that might arise in a professional setting. I think that adding a few examples of why certain functions are useful for certain business questions would have made this course a 5 star course.

When first signing up for this course, I didn't really think there was much I could learn since I have been working with SQL for 10+ years. However, I have had very little formal training, and because SQL has so many little tricks and functions, I learned far more than expected. Thanks for the excellent class!
