Any thoughts/brainstorming would be great from anyone :) Personally I don't have much experience with programming a database and the theory in it. But I suppose that in order to be able to go backward, the results already iterated through must be kept(at least a reference to it, something like rowId). If setToLast is used, I must use the sqlite3_step in order to find the last entry and then cache the other results. Is there an easier way?? Cheers Kim B.
