This is not true; the declarative extension serves as a holding zone for a MetaData object; like the MetaData object, it requires no association to any database engine at any time. The initial example in the declarative docunentation, which I am going to change right now, illustrates the engine being associated with the underlying MetaData as just as an example. The only time a databse connection is needed is when you are ready to query the database. You can create your Session and bind it to a newly created engine right before the first query is issued, if you like. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
