Learn how to write accurate and efficient SQL like a professional!

In this course, you will learn how to both read and write complex SQL queries in a relational database (MySQL). The skills you will learn are also largely applicable to any other major database system, such as PostgreSQL, Oracle Database, SQLServer, and much more.

Knowing how to write SQL is one of the fastest ways to reach your career goals. This is because SQL is consistently one of the most in-demand skill in the tech and business sectors. People who can work with data and manipulate it efficiently will be in high demand for many years to come. SQL allows you to be independent at work. It gives you the freedom to immediately get the answers to the questions you want to ask.

SQL can seem simple at first, but it can quickly become complicated. It is common for people to a write SQL query without realizing they are getting an incorrect result returned. This course is designed with a focus on accuracy and understanding.

I believe that the best way to learn SQL is by writing lots of SQL. For that reason, this course includes over 80 coding challenges where you get to write SQL queries and create database objects such as tables and stored procedures. These challenges are based on real-world scenarios and are designed for optimal understanding.
