How do I handle exceptions in ORM?

What are some common exceptions I might encounter when using ORM?

Common exceptions include IntegrityError, OperationalError, and ProgrammingError. Each indicates different issues.

How can I catch these exceptions in my code?

You can use try-except blocks to catch these exceptions. For example, wrap your database operations in a try block.

Can you show me a code example?

Sure! Here's a simple example:

try:
    session.add(new_record)
    session.commit()
except IntegrityError:
    session.rollback()
    print('Integrity error occurred!')

What should I do if I encounter an OperationalError?

For OperationalError, check your database connection settings and ensure the database server is running.
