To do that you need access to the rohan database to access the live data - not a smart thing to do even if you can.
You can't predict the stats on drop items except in very specific cases (i.e. Bezemut's Eyes). Others like dropped weapons with stats is not possible to predict ahead of time since they are set by a randomizing function in the server code.
--- Edit ----
After a quick discussion with Ishtaria (who knows far more about the numbers programming if a rohan server than I do) I need to revise what I said above.
While weapons and accs with stats do have some randomness as to what values are on the items dropped, the number, type and maximum amounts of those stats are set up totally in the .bin files.
Thanks Ish for the clarification.
