Essential SQLAlchemy introduces a high-level open-source code library that makes it easier for Python programmers to access relational databases such as Oracle, DB2, MySQL, PostgreSQL, and SQLite. SQLAlchemy has become increasingly popular since its release, but it still lacks good offline documentation. This practical book fills the gap, and because a developer wrote it, you get an objective look at SQLAlchemy's tools rather than an advocate's description of all the "cool" features. | Mapping Python to Databases O REILLY Rick Copeland www.it-ebooks.info Databases O REILLY Essential SQLAlchemy 7 Now Python developers can easily access relational databases such as Oracle DB2 and MySQL. Essential SQLAlcbemy walks you through simple L_________ queries demonstrates how to create database applications explains how to connect to multiple databases simultaneously with the same metadata and more. With this practical guide you ll learn how the SQLAlchemy open source code library lets you map objects to database tables without substantially changing your existing Python code. You ll also learn how to Create custom types for your schema and discover when to use them Create objects save them to a session and flush them to the database SQLAlchemy may be the best way to use a relational database from Python and this hook will certainly help you exploit SQLAlchemy s power if you start with a strong understanding of Python and SQL. Alex Martclli fiber tech lead Google Inc. and author of Python in a Nutshell O Reilly Run queries updates and deletes with SQLAlchemy s SQL expression language Build an object mapper and learn why it s different from active record patterns used in other ORMs Provide a declarative active record pattern for use with SQLAlchemy via the Elixir extension Use the SQLSoup extension to provide an automatic metadata and object model based on database reflection Use SQLAlchemy to model object-oriented inheritance This book gives you an objective look at SQLAlchemy from a developer s viewpoint rather than from an advocate s description. It s exactly what you need to quickly get up to speed with this code library. Essential SQLAlchemy provides much-needed guidance for programmers who are familiar with SQL but new to database mappers.
