However, as projects start to grow, the abstractions provided by the helpful ORM affect performance. The Tiqets back-end is persisted in Postgres across hundreds of tables. Among all these tables and their relationships, it’s easy to end up writing inefficient ORM queries, or reinventing the wheel where the ORM could have been used in a cleaner way.

Advanced SQLAlchemy Features You Need To Start Using If you are Python developer and you work with SQL databases, then SQLAlchemy is most likely a library you are familiar with. It’s a powerful, yet flexible toolkit for working with SQL in Python with lots of features. Some of these features like ORM and basic queries are common knowledge, but there are quite a few features you might not know about and should definitely be taking advantage of. So, let’s se how to leverage things like hybrid properties, nested queries, table metadata, dialects and more! Python Development Databases
Raw SQL vs Query Builder vs ORM After reading this article, you will know when to use raw SQL, a query builder and an ORM. You will also know how to use each of them in Python. All of the code in this article is runnable. You just need to initialize the database and add environment variables. Python Development Databases
