TUTORIAL: SQLAlchemy 2.0 by Mike Bayer @ Red Hat

In this tutorial, students will be introduced to SQLAlchemy 2.0 from the same perspective as its online tutorial; starting with fundamentals of database connectivity and transaction control, leading into table metadata design, construction of SQL queries, and finally into ORM-specific persistence patterns. The tutorial will target both early learners of SQLAlchemy as well as experienced users of the 1.x series. Familiarity with basic SQL concepts is strongly recommended.

The 5th annual Python Web Conf (#PWC2023) inspired attendees to use technology for good. The conference attracted 315 attendees from over 30 countries across 15 time zones. The highly engaging format featured 70 speakers, 5 tracks (including 64 talks and 5 tutorials) and took place virtually on March 13-17, 2023 on LoudSwarm by Six Feet Up.

You know when you are just learning something and the subject matter is so overwhelming (Python as much as SQLAlchemy). You chance upon someone that has such a brilliant understanding and conveys things clearly and logically and yet almost everything goes over your head. As you watch it again, more sinks in. The more you delve, the more appreciative you are of the elegance of the presenters execution. Mike Bayer is such a speaker and I thank him for being there at the beginning of my journey.

WOW! I have been working with raw sql - this totally blew my my mind 10/10 brilliant stuff. They should start teaching this in kindergarten.

Where can I find out about the chapter you had to skip at the end? Was honestly one of the most interesting topics for me and was a bit sad that the time ran out.

the topics are are not alongside one direction as I understand, running through somehow chaotically? But the best tutorial in web

Hi MIke, Thanks for the great tutorials as I try to absorb as much SQLAlchemy as possible. I came from a Java background where I used MyBatis as my ORM and loved it. On that note, I have a question. I want to issue raw SQL and have SQLAlchemy's ORM capability populate a collection of objects. That may not be pythonic, but I'd like to know how to do it with declarative mapping. Is it possible and, if so, I'd love to see an example.

Thx & rgds
