In my database I have an Email Campaign that has 1 to many List, List has many to many Subscribers.
The problem I'm having is, for example, when I pull a campaign I don't always want all the subscribers (could be a lot of subscribers and only wanting to see the different campaigns).
When creating mapping is there a way to optionally do the mappings (at runtime decide)? Or what is the solution to the problem? Should I just pull everything from database and output the portion requested? Seems like a lot of overhead.
