这个该如何实现

select SUBSTRING(FJM,1,5) as FJM,SUM(money) as money
from
(select SUBSTRING(FJM,1,9) as FJM,SUM(money) as money
from t
group by SUBSTRING(FJM,1,9))
T
group by SUBSTRING(FJM,1,5)
union
select SUBSTRING(FJM,1,9) as FJM,SUM(money) as money
from t
group by SUBSTRING(FJM,1,9) having SUM(money)>0
