Hi, Is there a way to do type hints for a generic DBAPI-compatible connection and cursor? Our ETL Helper tool uses cx_Oracle, psycopg2 and sqlite3 connections interchangeably and it would be useful to have a generic type instead explicitly using the classes from each driver.
As far as I can see from Google, one way to achieve this would by using Protocols, as defined in PEP 544 (https://peps.python.org/pep-0544/). Is there an "official" PEP 249 DBA API 2.0 protocol anywhere? Thanks, John p.s. ETL Helper is a library we developed to make it easier for our DBAs to use Python to transfer data. https://pypi.org/project/etlhelper/ This email and any attachments are intended solely for the use of the named recipients.
