Setting up SQL databases

In the world of data handling, the power of Python meets the efficiency of SQL databases. This recipe aims to introduce you to how to integrate SQL databases within your application, a crucial skill for any developer looking to build robust and scalable web applications.

SQL is the standard language for managing and manipulating relational databases. When combined with FastAPI, it unlocks a world of possibilities in data storage and retrieval.

FastAPI’s compatibility with SQL databases is facilitated through ORMs. The most popular one is SQLAlchemy. We will focus on it in this recipe.

Getting ready

To begin, you’ll need to have FastAPI and SQLAlchemy installed in your virtual environment. If you followed the steps in Chapter 1, First Steps with FastAPI, you should have FastAPI already set up. For SQLAlchemy, a simple pip command is all that’s needed:

$ pip install sqlalchemy

Once installed, the next step is to configure...
