Flask ORM vs SQL: Which Should I Use?

What are the main differences between Flask ORM and raw SQL?

Flask ORM, like SQLAlchemy, provides an abstraction layer over SQL, making it easier to work with databases using Python objects. Raw SQL, on the other hand, requires writing SQL queries directly, giving you more control but also more complexity.

When should I choose Flask ORM over raw SQL?

You should choose Flask ORM when you want to simplify database interactions, especially for complex queries or when working with multiple database types. It's also great for rapid development.

Are there any performance drawbacks to using Flask ORM?

Yes, there can be performance drawbacks, especially for very complex queries or large datasets, as ORM can introduce overhead. However, for most applications, the trade-off in development speed and maintainability is worth it.

Can I mix Flask ORM and raw SQL in my project?

Absolutely! You can use Flask ORM for most operations and fall back to raw SQL for specific cases where performance is critical or when you need complex queries.
