[aminalaee]

• Fix Row imports from SQLAlchemy
• Rename output of query, _, _ = compile(query) to query_str, _, _ = compile(query)

@aminalaee Why this change? They changed in sqlalchemy? My PR was wrong ? If that's the case surely we could have an extra test to ensure the behaviour was wrong and is now good.
Sorry I'm just trying to understand the context

@PrettyWood
Right now Row is imported from from sqlalchemy.engine.result
But Row is not defined in there, it's just imported in result.py and it's defined in sqlalchemy.engine.row.
If you jut click on the current Row import you will go to sqlalchemy.engine.row not engine.result.

It's a matter of formatting, and the code is working alright.

P.S.: I don't know if SQLAlchemy changed that or not, but that works ok because Row is relatively imported in sqlalchemy.engine.result so it can work but I think IDEs will complain about that import.

Sorry but it wasn't anything personal, I was working on another IDE error and found this too.

Haha don't worry 😉 I wasn't concerned about anything like this. Was just surprised tests were working fine if the import was wrong. Thanks for clarifying!
