You have to save one by one. But that's just as simple as iterating through the list items and calling Save method for each of them.
But, how do i control the transaction?
IDBConnection property provides a BeginTransaction method that returns a IDBTransaction interface with Commit and Rollback methods:
As far as I see this won't work for inserting objects.
In class TInserter the transaction will be commited while this not happens in TDeleter or TUpdater. Is this intended?
I would prefer a way to run complex sequences of adding, updating and deleting objects within a transaction.
It should work with inserting as well. The transactions managed by IDBConnection can be nested.
