Overview of this book

Python is a dynamic programming language, which is completely enterprise ready, owing largely to the variety of support modules that are available to extend its capabilities. In order to build productive and feature-rich Python applications, we need to use MySQL for Python, a module that provides database support to our applications. Although you might be familiar with accessing data in MySQL, here you will learn how to access data through MySQL for Python efficiently and effectively.This book demonstrates how to boost the productivity of your Python applications by integrating them with the MySQL database server, the world's most powerful open source database. It will teach you to access the data on your MySQL database server easily with Python's library for MySQL using a practical, hands-on approach. Leaving theory to the classroom, this book uses real-world code to solve real-world problems with real-world solutions.The book starts by exploring the various means of installing MySQL for Python on different platforms and how to use simple database querying techniques to improve your programs. It then takes you through data insertion, data retrieval, and error-handling techniques to create robust programs. The book also covers automation of both database and user creation, and administration of access controls. As the book progresses, you will learn to use many more advanced features of Python for MySQL that facilitate effective administration of your database through Python. Every chapter is illustrated with a project that you can deploy in your own situation.By the end of this book, you will know several techniques for interfacing your Python applications with MySQL effectively so that powerful database management through Python becomes easy to achieve and easy to maintain.

Creating databases


Creating a database in MySQL is as simple as declaring the name of the database that you want to create. The syntax reads:

CREATE DATABASE <database name>;

An example of this is:

CREATE DATABASE csv;

As with all SQL statements, blank space is the token by which the command is divided. We first need to tell MySQL that we want to create something by using that keyword. Then we need to tell it what we want to create, a database. Finally, we give it the name of the database followed by the requisite semi-colon (when in MySQL itself).

Note

Note that, in order to create databases in MySQL, the account you use must have the CREATE privilege on the database.

CREATE statements are also sensitive to user privileges. If a user is only granted CREATE privileges on a single database (for example, csv.*), then that user cannot create databases, but can create tables on that specific database.

Unlike some commands in MySQL, database creation is case-sensitive. So the following CREATE statements...
