select t1.FItemID PId,t2.FItemID,t2.FQty 
from ICBOM t1 left join ICBOMCHILD t2 on t1.FInterID =t2.FInterID where  and FUseStatus=1072 and t2.FItemID>0
union all
select  t1.FItemID PId,t2.FItemID ,t2.FQty    from ICBOM t1 left join ICBOMCHILD t2 on t1.FInterID =t2.FInterID 
where  and FUseStatus=1072 and t2.FItemID>0

union all：并联的两个查询的字段数必须一致
