SQL stands for Structured Query Language. It is used to retrieve data that is located in tables in a relational data-base.

SQL abilities are enormous, and the better you know it, the better your abilities to gain data and insights about it would be.

In this course I'll teach you all the elements of SQL, and I'll do it by writing queries. A lot of queries. I believe that the best way to learn SQL is to practice it with all kind of possible queries and manipulations, and that's what I'll do in this course.

Every lesson in this course contains example queries, exercise and all of them are available for you as source code to download.

In addition, I supply to you a full and functioning DB, with a lot of data, so you can try by your own your SQL skills.

Who should take this course?

If you learn an academic course on data bases, you probably have SQL part. This course can give you all the needed knowledge for answering SQL questions in University and colleges exams on SQL.

If you are a developer who wants to integrate data base in your application - this course is for you.

After completing the course you'll be able to write any SQL query in order to retrieve any data you want from a data base.
