This will do it out of game, and it's not a bad query at all (about 2 seconds on my machine):
Code:
select distinct n.id, lt.loottable_id, n.Name, i.Name, s.zone, lt.probability/100*ld.chance/100
from npc_types n
inner join loottable_entries lt on n.loottable_id = lt.loottable_id
inner join lootdrop_entries ld on ld.lootdrop_id = lt.lootdrop_id
inner join items i on ld.item_id = i.id
inner join spawnentry se on n.id = se.npcID
inner join spawn2 s on se.spawngroupID = s.spawngroupID
where i.id = '1001'
order by n.id;
That will spit out the item id, loottable id, npc's name, item name, zone the npc is in, and total chance the item will drop (in decimal 1.0 = 100%, 0.04 = 4%)
Obviously, change the item number where 1001 is and you're set. Might want to output the results to a file, or change what it spits out. Eliminating the zone (and all the spawn group queries with it) will reduce the amount of results.
Damn, Wildcard you and I spend too much time talking our queries are nearly identical. Not many ways to do this I guess.
