下面的sql如何修改 select from select gold1000 as gold from vp_user UNION select sumsiprice 45 1000 as inventory_gold from economyvp_user_inventory ui join economyvp_steam_item as si on uiitem_id = siid

SELECT * FROM ( SELECT gold/1000 AS gold FROM vp_user UNION SELECT SUM(si.price)*45/1000 AS inventory_gold FROM economy.vp_user_inventory ui JOIN economy.vp_steam_item as si ON ui.item_id = si.id ) AS result_table;
