Course Description

The course has everything you need to start writing your own SQL queries.
The SQL language seems simple - and that's true. However, some topics can cause mistakes - things like NULL values, duplicate rows and missing rows, etc. This course covers the frequent mistakes, and how to avoid them.
You will learn SQL syntax applicable to most relational databases. In the practice exercises you will use PostgreSQL, but the knowledge is easily transferable to other databases. The standard SQL is the same in all ANSI-compliant SQL databases.
The course has English subtitles (closed captions) manually created!
Check out the free preview videos for more information!
I'll be happy to see you inside the course!Who this course is for:
  • Those who do not know SQL at all.
  • Those who know some SQL commands, but are not quite comfortable using them.

Nice course! the instructor is clear and using good illustrations. Good for beginners.

One world for this course is short and sweet, Best for refresh for interview

Enjoyed this course very much. Lecturer explains very well with very efficient lesson material. Had to do some changes to the syntax queries as I am using SQL Server, but it was still mostly relevant. The exercises is also designed to let you think and let you display your learned knowledge. Will recommend this course for beginners in SQL. WELL DONE!!

A great introduction to SQL. This should give me a good starting point to develop and further my career prospects!Many thanks!

The syntax did not work on the current programs

Good pace and high-level overview, I am able to follow along to this new subject matter.

Vlad was a great teacher! He explained the concepts well and the example slides were very helpful. A+

First of all, thank you for the course. As a beginner from scratch, i was able to understand and grasp everything by the style of teaching and explanation. Loved the exercises of which I was able to tackle and wished there were more to continue the practice. I will surely see you again in my next courses

Great course for beginners in SQL. Thanks for your efforts!

I have been using sql a while but this was easy to follow and a great refresher course on some commands that I have seldom used.

The instructor goes straight to the point, explaining things that are not usually taught. I highly recommend this course. Thank you.

excellent course for anyone who wants to set a foundation for SQL.
