SQL is a powerful language for querying and manipulating data, but it’s tough to integrate it with your application. SQLAlchemy helps you map Python objects to database tables without substantially changing your existing Python code. If you’re an intermediate Python developer with knowledge of basic SQL syntax and relational theory, this book serves as both a learning tool and a handy reference.
Dive into SQLAlchemy, the popular, open-source code library that helps Python programmers work with relational databases such as Oracle, MySQL, PostgresSQL, and SQLite. Using real-world examples, this practical guide shows you how to build a simple database application with SQLAlchemy, and how to connect to multiple databases simultaneously with the same metadata.
This new edition of Essential SQLAlchemy is the tool developers need to understand the technology. Rather than being a simple tutorial or API reference, this book builds an application step by step. This application is comprised of many of the most common usages of SQLAlchemy, thus showing how to manage complexity and engaging in real world examples. Using easy, common language, the authors teach you how to turn knowledge into usable work.
Essential SQLAlchemy includes several sections:SQLAlchemy Core: Provide database services to your applications in a Pythonic way with the SQL Expression Language.
SQLAlchemy ORM: Use the object relational mapper to bind database schema and operations to data objects in your application.
Alembic: Use this lightweight database migration tool to handle changes to the database as your application evolves.
Cookbook: Learn how to use SQLAlchemy with web frameworks like Flask and libraries like SQLAcodegen.
