PCPP2 Database Access Practice Question

You are developing an application using SQLAlchemy and need to retrieve a single object by its primary key. Which method is preferred for this operation?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

session.get(Model, pk)

The get() method on the Session object is the optimized way to retrieve an object by its primary key.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Model.find(pk)

    Why it's wrong here

    Model classes do not have a find method in SQLAlchemy.

  • session.get(Model, pk)

    Why this is correct

    session.get() is designed specifically for primary key lookups.

  • session.fetch(Model, pk)

    Why it's wrong here

    fetch is not a valid method on the session object.

  • session.query(Model).filter(Model.id == pk).first()

    Why it's wrong here

    While this works, get() is more efficient and idiomatic.
