怎么把两个查询的结果按字段相减啊（关键字hzjxsdm）

[解决办法]
Select A.sl - B.sl As sl, A.gcts - B.gcts As gcts, A.dkje - B.dkje As dkje, A.hzjxsdm
From
(
select isnull(count(hth),0) as sl,isnull(sum(gcts),0) as gcts,isnull(sum(dkje),0) as dkje,hzjxsdm from ht where yxbz= '1 ' and convert(char(6),isnull(gsldshrq, ' '),112)= '200707 ' and isnull(bgsj, ' ') <> ' ' group by hzjxsdm
) A
Inner Join

(
select isnull(count(hth),0) as sl,isnull(sum(gcts),0) as gcts,isnull(sum(dkje),0) as dkje,hzjxsdm from ht where yxbz= '0 '
and (hth like '%*01 ' and isnull(fpbz, ' ') <> '1 ') and convert(char(6),isnull(gsldshrq, ' '),112)= '200707 ' group by hzjxsdm
) B
On A.hzjxsdm = B.hzjxsdm
