你可以嘗試這樣的...

SELECT Sum(xxx) as xxx,Sum(yyy) as yyy from (
    select '' as xxx,pawn.propawn_price as yyy from product_pawn pawn 
    inner join product_history history on history.propawn_id = pawn.propawn_id 
    and history.prohistory_status = '0' 
    union 
    select pawn.propawn_price * 8/100 as xxx,'' as yyy from product_pawn pawn 
    inner join product_history history on history.propawn_id = pawn.propawn_id 
    and history.prohistory_status = '1' 
    union 
    select pawn.propawn_price + pawn.propawn_price * 8/100 as xxx,'' as yyy 
    from product_pawn pawn 
    inner join product_history history on history.propawn_id = pawn.propawn_id 
    and history.prohistory_status = '2' 
    union 
    select prosell_pricesell as xxx,'' as yyy from product_sell 
    where prosell_status = '5') t
