Overview of this book

This book will take you through all the nitty-gritty parts of MariaDB, right from the creation of your database all the way to using MariaDB’s advanced features. At the very beginning, we show you the basics, that is, how to install MariaDB. Then, we walk you through the databases and tables of MariaDB, and introduce SQL in MariaDB. You will learn about all the features that have been added in MariaDB but are absent in MySQL. Moving on, you’ll learn to import and export data, views, virtual columns, and dynamic columns in MariaDB. Then, you’ll get to grips with full-text searches and queries in MariaDb. You’ll also be familiarized with the CONNECT storage engine. At the end of the book, you’ll be introduced to the community of MariaDB.

Chapter 5. Views and Virtual Columns

Sometimes, we may want to shift some data logic from an application to the database. In order to do this, we can use two important features called views and virtual columns. These are objects that can be seen as tables or columns that are automatically populated with the data calculated by MariaDB. These features can also be used to add security to our database, or to solve some performance problems.

This chapter will cover the following topics:

Views
VIRTUAL columns
PERSISTENT columns
