Useful SQL Queries and Commands
At some point you will need to store data in a database and this blog post should help you get familiar with a SQL database like mySQL (there are other SQL databases like PostgreSQL). I want to cover some basic concepts like setting up the database, specifying proper structure or schema, and playing with tables, columns, and rows. I will focus mostly on SELECT queries but also cover INSERT, UPDATE, DELETE, plus some math functions and regular expressions. I feel like learning SQL seems scary at first so I am hoping that this quick guide will alleviate some of these fears. I will use SQLfiddle (website for testing and sharing SQL queries) and the concept of a blog to work through some common mysql examples and database concepts.
