You wont be able to take advantage result = db.session.execute('SELECT * FROM my_table WHERE my_column = :val', {'val': 5}) All your application queries should be going through a session object, whether they're raw SQL or not. Connection, Engine, default, and url are several other callables with code examples from the same sqlalchemy.engine package.. Python has many gui libraries and tkinter is one of them that is supported natively, that is you dont need to install any extra modules. Its home base for the actual database and its DBAPI, delivered to the SQLAlchemy application through a connection pool and a Dialect, which describes how to talk to a specific kind of database/DBAPI combination.. To answer your question bluntly, yes! You can achieve similar results using flat files in any number of formats, including CSV, For example, given this very basic example. Parameters. It's power comes from the object-oriented way of "talking" to a database instead of hardcoding SQL statements that can be a pain to manage. create_engine is a callable within the sqlalchemy.engine module of the SQLAlchemy project..
