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. A practical manual packed with step-by-step examples to manage your MySQL database efficiently through Python What you will learn from this book •Explore the various means to install MySQL for Python, from using an egg to unrolling a tarball •Query the database and retrieve records through MySQL for Python •Implement insertion of data into a MySQL database in Python •Carry out error-handling in MySQL for Python in order to ensure the robustness of programs •Use secure logging techniques to record how your users use your programs •Carry out record-by-record retrieval to save a lot of overhead while retrieving data •Handle insertion of large amounts of data using iteration and the executemany function •Automate the creation and removal of databases and tables using MySQL for Python •Use the MySQL for Python library to automate user creation and to administer access controls •Log user activity with MySQL for Python by using MySQL's date and time support •See how to revise database programs to include more functionality •Use aggregate functions to make MySQL take the burden off your web server •Save time and processing resources by scripting JOINs and subqueries
