Overview of this book

MariaDB is a database that has become very popular in the few short years that it has been around. It does not require a big server or expensive support contract. It is also powerful enough to be the database of choice for some of the biggest and most popular websites in the world, taking full advantage of the latest computing hardware available. From installing and configuring through basic usage and maintenance, each chapter in this revised and expanded guide leads on sequentially and logically from the one before it, introducing topics in their natural order so you learn what you need, when you need it. The book is based on the latest release of MariaDB and covers all the latest features and functions. By the end of this beginner-friendly book, not only will you have a running installation of MariaDB, but you will have practical, hands-on experience in the basics of how to install, configure, administer, use, and maintain it.

Creating, altering, and dropping tables

Now that we know a little about how data is structured in a database, we can learn more about creating our own tables, making changes to them, and even how to delete them.

Using CREATE TABLE

We use the CREATE TABLE command to create tables. For a basic database for an online store, we might have tables for customers, products, orders, product reviews, customer addresses, and more. We can create as many tables as we need, but as mentioned previously, we should give the design some thought so that we don't store duplicate or unused data. That said, don't worry about this too much, as we can always make changes later with the ALTER TABLE command (see the Using ALTER TABLE section later in this chapter).

Using CREATE TABLE – basic syntax

The basic syntax of the CREATE TABLE command is as follows:

CREATE TABLE table_name (<column_definitions>);

As with creating a database, we can add an IF NOT EXISTS command before the table name to suppress the error...
