What are common exceptions in SQLAlchemy Async?

What are some common exceptions I might encounter when using SQLAlchemy Async?

In SQLAlchemy Async, you might encounter exceptions like NoResultFound, MultipleResultsFound, and IntegrityError. Each of these indicates different issues with your queries or database constraints.

Can you explain what NoResultFound means?

NoResultFound is raised when a query that is expected to return a result does not return any. This often happens with get() or one() methods.

What should I do if I encounter an IntegrityError?

An IntegrityError typically indicates a violation of database constraints, such as unique constraints. You should check your data for duplicates or ensure that your foreign key relationships are valid.

Are there any best practices for handling these exceptions?

Yes, it's best to use try-except blocks to catch these exceptions and handle them gracefully, providing user-friendly error messages or logging the errors for debugging.
