Good afternoon guys, I'm brand new to SQLAlchemy as of about 2 minutes ago, I have a couple of starter questions that I wanted to run past you, with any luck they'll be simple for you to answer.
After looking through the quick tutorial, which showed me just about all I need to know http://www.sqlalchemy.org/docs/05/ormtutorial.html it talks about connecting to an in memory sqllite database using a connection string like so: create_engine('sqlite:///:memory:', echo=True) How would I connect to a local MySQL database? The database I'm working with is already designed and built, which leads me onto my next question: In the tutorial documentation it talks about 'Defining and Creating a Table'. Is this something which need only be done when we're working with an in-memory database? or do I have to define my database schema even if its a pre-existing mysql database? or does SQLAlchemy introspect it or something? My thrid and final question is about the persistance of composed objects. If I save an object using sql alchamy, I see it also saves the objects children. Is this done in a transaction by default? if the save process on one of its children fails will it all be rolled back? or is this something I have to specify seperatly? Thanks guys, once I know those little items I'm sure I'll be able to get up and running pretty swiftly.
