I think I have a strategy for how to solve this in a better fashion though, but I would like to hear your thoughts on what all the issues are;

detachResult is not a good compromise because it means you need to have the decoupled version there in any case, but only invoking in on request.
Well I think the idea with detachResult is to hide ... |

In any case, going away from decoupled interfaces needs good reasons, not the opposite.
I think the burden is on us both. I think you have good points and I think I have good points. And I hope w ... |

It seems that decoupling:
1) introduces a cyclic import dependency - this is how Mysql trunk is - unless you get around it with an interface
Please point me to the cyclic dependencies.

Ok, I still need to be convinced that Database and Result should be decoupled.
A technical reason? I don't have one.
It's a matter of expectations. As an end user, I see a class named Database a ... |

That's not a "MultiResult" - this is just row by row fetching.
Okay. The fact remains that I don't see how to accomplish this in ddbi or in your fork.
Hmm... well Mysql doesn't allow ... |

Oh! I finally understand Statement now!
Statement.execute executes a query. This query can return multiple rows, but you don't actually retrieve them in this step.
Statement.fetch retrieves a ro ... |

Additionally, you don't allow anyone to bind anything without using strong typing, and you don't allow people to bind one argument to a Statement at a time. This means that I wouldn't be able to u ... |

Ok, with regards to prepared statements and multi-result sets, can you please mention a database that supports this feature?
