Do you want to add the full power, functionalities, and flexibilities of SQL to your Python GUI App? You can build it easily by combining SQLAlchemy and Python4Delphi library, inside Delphi and C++Builder.

SQLAlchemy is the Python SQL toolkit and Object Relational Mapper that gives application developers the full power and flexibility of SQL. SQLAlchemy provides a full suite of well-known enterprise-level persistence patterns, designed for efficient and high-performing database access, adapted into a simple and Pythonic domain language.

The following are Major SQLAlchemy features:

 

Hands-On

This post will guide you on how to run various SQL and Object Relational Mapper operations using Python’s SQLAlchemy library and then display it in the Delphi Windows GUI app using Python for Delphi.

First, open and run our Python GUI using project Demo1 from Python4Delphi with RAD Studio. Then insert the script into the lower Memo, click the Execute button, and get the result in the upper Memo. You can find the Demo1 source on GitHub. The behind the scene details of how Delphi manages to run your Python code in this amazing Python GUI can be found at this link.

Let’s perform some sanity check and introductory examples of the SQLAlchemy library:
