MySQL的總和之列

-1

 SELECT tbl_trans.trans_username, 
    Sum(Case When tbl_trans.trans_type <> 'REWARD' AND tbl_trans.trans_winlose <> 'QB' then 
     trans_winloseamount Else 0 End) BETHOST, 
    Sum(Case When tbl_trans.trans_winlose = 'QB' then 
     trans_winloseamount Else 0 End) QB, 
    Sum(Case When tbl_trans.trans_type = 'REWARD' then 
     trans_winloseamount Else 0 End) reward , 
     Sum(sum(BETHOST)+sum(QB)+sum(reward)) totalsum 
FROM tbl_trans 
GROUP BY trans_username

我需要totalsum BETHOST，QB和獎勵
如何總結這Sum(sum(BETHOST)+sum(QB)+sum(reward)) totalsumMySQL的總和之列
