By John Routh on 3/19/2020

This is very good for beginners who want to learn new skills. Very easy to follow and replicate in your own environment.

By Ray Cordova on 2/14/2020

Love the course. This is exactly the course I need to use for TOAD. Might be beneficial to have a how-to course for the tool itself. Excellent delivery on how to set this up on a personal workstation.

THIS COURSE WAS SO HELPFUL TO ME THANKS FOR THE EXPLANATION MAY GOD BLESS YOU

By Tom McCarthy on 4/26/2018

Helpful course, used it as a refresher. Instructor did a good job making things easy to understand.

By King Skull on 11/20/2017

Very, very useful for a beginner (such as myself). Most videos are a few minutes long which makes it ideal for learning. It only includes easy examples. I would've love to see a section dedicated to more difficult queries; not to go in depth (as this is a basic SQL course) but to show what kind of queries are done out there in the real world to combine multiple tables, with multiple data types (timestamps, dates, Unix time stamps, etc). This was my first course in Udemy . I found that playing the course at 1.5x speed feels right. At 2x speed it's also good in some lectures. Normal speed was way too slow. If you have zero experience with dbs or have just a little, then, this is a good course. Worth it!

I am currently about 1/3 of the way through this course. I really like the content and would give it 4-5 stars if the video quality could be improved.

By Matt bailey on 8/26/2016

I like how methodical the course syllabus is thus far -- very thorough, step by step. However, some of the screenshots have poor resolution. Sometimes, I wish he would move things along more quickly. I'd also like it if there were a walk-through of the Toad UI.
