Structured Query Language

SQL (pronounced ess-queue-el or sequel) is a popular programming language that communicates with databases. It is widely popular because its syntax is intuitive and fairly easy to learn.

In this site, I will be dedicating a series of blog posts to show how to use SQL by describing and applying 100 must-know beginner functions. Every week, I will be publishing 10 functions that you can try yourself.

For the exercises, I will be specifically using PostgreSQL which is a free and open source SQL software that can be used in your computer Terminal or through its graphical interface pgAdmin. You can find the documentation here if you want to read up more.
