-- Note: If you're running a MySQL version earlier than 5.0 (or if this scripts fails for you for any reason)
-- you'll need to run the following queries manually:
--
-- [ Pre-Renewal only ]
-- ALTER TABLE item_db2 ADD COLUMN `matk` smallint(5) unsigned DEFAULT NULL AFTER atk;
-- ALTER TABLE item_db2 CHANGE COLUMN `equip_level` `equip_level_min` smallint(5) unsigned DEFAULT NULL;
-- ALTER TABLE item_db2 ADD COLUMN `equip_level_max` smallint(5) unsigned DEFAULT NULL AFTER equip_level_min;
-- [ Both Pre-Renewal and Renewal ]
-- ALTER TABLE item_db2 MODIFY COLUMN `price_buy` mediumint(10) DEFAULT NULL;
-- ALTER TABLE item_db2 MODIFY COLUMN `price_sell` mediumint(10) DEFAULT NULL;
-- ALTER TABLE item_db2 MODIFY COLUMN `weight` smallint(5) unsigned DEFAULT NULL;
-- ALTER TABLE item_db2 MODIFY COLUMN `atk` smallint(5) unsigned DEFAULT NULL;
-- ALTER TABLE item_db2 MODIFY COLUMN `matk` smallint(5) unsigned DEFAULT NULL;
