求SQL语句修改

select ays_cost_d.cbs, isnull(sum(ays_cost_d.amt),0) as CB,isnull(((select isnull(sum(pay_amt_d.rep_amt_fc),0) from pay_amt_d left join bd_cbs on pay_amt_d.cbs=bd_cbs.cbsid where bd_cbs.cbsid='10094311')+

(select  isnull(sum(kc_billbody.mony),0)  from  kc_billbody left join bd_cbs on kc_billbody.cbs=bd_cbs.cbsid where bd_cbs.cbsid='10094311')+

(select isnull(sum(fyb_indirect_c.amt_fc),0) from fyb_indirect_c left join bd_cbs on   fyb_indirect_c.cbs=bd_cbs.cbsid where bd_cbs.cbsid='10094311')),0) as SJ

from ays_cost_d left join bd_cbs on ays_cost_d.cbs=bd_cbs.cbsid where bd_cbs.cbsid='10094311'  group by ays_cost_d.cbs

    求高手指导  如何把这个语句糅合成只需要一个定位条件，现在是有四个定位语句！！
