How do I handle errors in SQLAlchemy async operations?

In SQLAlchemy async operations, you can handle errors using try-except blocks. This allows you to catch exceptions that may occur during database interactions.

Can you give me an example of how to implement that?

Sure! Here's a simple example:

async def fetch_data(session):
    try:
        result = await session.execute(select(MyModel))
        return result.scalars().all()
    except Exception as e:
        print(f'An error occurred: {e}')

What types of exceptions should I be aware of?

You should be aware of exceptions like SQLAlchemyError, IntegrityError, and OperationalError, among others. Each serves a different purpose.

Is there a way to log these errors for later review?

Yes, you can use Python's logging module to log errors. Just replace the print statement with a logging call, like logging.error(f'An error occurred: {e}').
