Code:
DELETE FROM creature_loot_template WHERE ( entry = '7039' AND ( item = '63333' OR item = '63334' OR item = '63335' OR item = '63336'));
INSERT INTO creature_loot_template (entry, item, ChanceOrQuestChance, lootmode, groupid, mincountOrRef, maxcount) VALUES
('7039','63333','-50','1','0','1','1'),
('7039','63334','-50','1','0','1','1'),
('7039','63335','-50','1','0','1','1'),
('7039','63336','-50','1','0','1','1');
Tested : Ok!
