you have more options here than previously on how to treat rows, as tuples or mappings, either up front or on a per-row basis. the new API has been available as of version 1.4. Relevant links include: 1. announcement of change and rationale https://docs.sqlalchemy.org/en/14/changelog/migration_14.html#rowproxy-is-no-longer-a-proxy-is-now-called-row-and-behaves-like-an-enhanced-named-tuple 2. migration guide https://docs.sqlalchemy.org/en/14/changelog/migration_20.html#result-rows-act-like-named-tuples 3. new tutorial coverage https://docs.sqlalchemy.org/en/14/tutorial/dbapi_transactions.html#fetching-rows included is background on how to get mappings from a Row or how to get RowMapping objects from a result up front using result.mappings(). > > Matthew > > > -- > SQLAlchemy - > The Python SQL Toolkit and Object Relational Mapper > > http://www.sqlalchemy.org/ > > To post example code, please provide an MCVE: Minimal, Complete, and > Verifiable Example.
