* Covers Oracle Database 11g, Oracle 12c, Oracle 18c, and Oracle 19c
Oracle is currently the most popular relational database management system in the world. It is used by thousands of big companies who are usually willing to pay good salaries to the right people, which includes those with practical Oracle SQL knowledge that is based on best practices and experience.
Most SQL courses give you theoretical SQL knowledge. In this course, you will learn by actually writing code.
What do other learners say about this course?
-
Shruti says: “It was such an amazing course. Absolutely a beginner friendly course”.
-
Daniel says “Excellent match. In spite of knowing sql for more than a decade, learnt a loooot of new stuff.”
-
David says: “Really well explained! Love the energy of the instructor!”.
-
Scott says: “This is an incredible course! I love how the instructor Carlos presents topics very clearly, but also challenges students in the quizzes and practice challenges. Too many courses out there contain practice challenges that are exact replicas of what was just taught, which are too easy and limit growth of the student. I have no suggestions for improvement on the course content and presentation, as it was simply perfect in my opinion. … I would rate this course higher than 5 stars if that were possible. Thank you Carlos!”
-
Thomas says: “Honestly, I’ve seen some good udemy courses… This course is one of the best structured iv’e seen. It places a priority on the practice challenges that allows the quality of the course to rival a university course … Great instruction, great value for the course!”
-
Roshan says: “great course to cover all the fundamentals, great for interview preparations.”
-
Paul says “This course is very thorough, and Carlos is a skilled instructor!”
-
Radu says “Very clear course, concise presentation, excellent tips, very good pronunciation, captions without errors, lots of exercises for practice… Thank you for the excellent course, Carlos.”

Carlos created this course because most courses, if not all, focus too much on “telling” or “demonstrating” how to do things, but don’t give you, as a student, the opportunity to test and practice what is being taught. Some of them tell you to practice or to do things along with the instructor, but unfortunately, such an approach doesn’t really work. Seeing how things are done or just copying or repeating what you see on the screen is not going to help you learn SQL. You might feel that you are learning, but when the time comes for you to write a command on your own, you are most likely not going to feel very confident.
Here you will learn and practice much more than just SQL basics.
Content and Overview:
This course will not only help beginners learn the SQL language. If you already have previous SQL knowledge, you will also learn a lot of new concepts, features and techniques that will make you an even better SQL developer.
After setting the learning environment, it starts with the most basic concepts about databases in general and a very short introduction to Oracle and the SQL language.
You will start learning about the simplest SQL statements, and before you even notice it, you will have covered all the SQL basics and will be gradually progressing to more advanced concepts.
The course includes several topics that some people, including experienced developers and other instructors, consider advanced, such as Analytic Functions, Hierarchical Queries, Pivot and Unpivot features, and many more.
It does not include demonstration lectures because the whole course is a coding demonstration. In 90% of the video lectures, you will be watching the instructor’s computer screen while he types, explains, and runs Oracle SQL code.
It does not include labs at the end of each section because practically every lesson has a coding task for you to practice what you are learning.
Please note that PL/SQL (Oracle’s procedural language) is not covered in this course.
The instructor will not only teach you SQL. He will share his decades of Oracle experience with you through what he calls “experience tips”. Those tips can really help you differentiate and stand out.
Final words from the instructor:
You could enjoy being seen as an experienced and knowledgeable SQL developer by your friends, peers, and potential employers in a very short time, but you have to take action. If you want my help, you’ve got it.
-Carlos, founder of the Standout-Dev Academy.
