Sqlalchemy orm is too slow, it's better to use sqlalchemy core

The best tutorial of sqlAlchemy. Perfect combination of nicely organized content, clear voice and detail explanation. Thanks!

Nice tutorial. I like that you kept the code and files to a minimum while still showing core concepts. I am newish to OOP and SQLAlchemy 2.0 so it helps with the learning curve.

Hi @Demos.. How can we add ondelete constraint after we have already created the table, without having to delete the tables and the records.
ОтветитьTop quality content❤❤!! Can you also make a detailed video on flask-sqlalchemy... or is it same
Ответить
It's really good
Please guide me to next step what should I learn after this course
If I could I would give 100 likes on this video

What we don't need is another intro to Sqlalchemy
What we do need is a tutorial on how to write advanced Sqlalchemy queries using window functions (rank, dense, row number), etc.
Nice tutorial! That really helped me to understand db queries 👍
