In this article we’ve explored the start of sql alchemy; we know how to connect to the database and how to execute raw sql. also we’ve discussed the benefits of using the orm over executing raw sql. The orm layer provides a way to interact with your database using python objects rather than writing raw sql queries. this tutorial introduces the basics of sqlalchemy orm, including setting up a database, defining models, and performing crud operations. In the next sections, we’ll explore sqlalchemy orm, which provides a higher level of abstraction, allowing you to work with python objects instead of sql expressions. This tutorial offers a practical approach to executing raw sql queries in sqlalchemy, providing clear examples and tips for efficient database management.
