Re:Simple SQL in Python

I'm relatively new to Python and I was looking for something like this. I do wonder if there is a well-known Python equivalent of Dapper: https://github.com/StackExchange/Dapper

You don't need Dapper for Python. Python is a dynamic language. If your problem is hydration[0] it can be done easily, even with Python classes.

For query building SQLAlchemy can do that and more.
I think that, with JSON support in most RDBMS, ORM as a concept has become way easier to handle. I come to think that this is the promise of the 90's Object oriented databases being fulfilled somehow.

Hydration is not a big problem. However, Dapper does much more than that: it handles multi-mapping (eg mapping users and posts from a single query), query parameterization etc. Surely, you can do it all ad hoc, but Dapper provides very convenient set of primitives out of the box.

You can achieve all that with JSON support in SQL, which most RDBMS have. You can then de-serialize JSON rows into Python objects. No need for an ORM.
