-- 一:只有一个分类汇总列时,只需要一个合计,只需要增加with rollup即可

select case when grouping(a) = 1 then '合计' else cast(a as varchar) end as a,
	sum(b),sum(c),sum(d),sum(e) from #t group by a with rollup

-- 二:有多个分类汇总列,只需要一个合计.增加rollup之后,需要增加判断

select case when grouping(a) = 1 then '合计' else cast(a as varchar) end as a,b,
	sum(c),sum(d),sum(e) from #t group by a,b with rollup
	having grouping(b) = 0 or grouping(a) = 1


select case when grouping(a)=1 then '合计' else cast(a as varchar) end a,
    b,
    c,
sum(d),sum(e) from #t 
group by a,b,c with rollup 
having grouping(c)=0 or grouping(a)=1


-- 三:有多个分类汇总列,需要全部的小计和合计。

select case when grouping(a) = 1 then '合计' else cast(a as varchar) end as a,
       case when grouping(b) = 1 and grouping(a) = 0 then '小计' else cast (b as varchar) end as b,
       case when grouping(c) = 1 and grouping(b) = 0 then '小计' else cast (c as varchar) end as c,
	sum(d),sum(e) from #t group by a,b,c with rollup


-- 四:有多个分类汇总列,需要部分的小计和合计

select case when grouping(a) = 1 then '合计' else cast(a as varchar) end a,b,
       case when grouping(c) = 1 and grouping(b) = 0 then '小计' else cast(c as varchar) end c,
       sum(d),sum(e) from #t 
	group by a,b,c with rollup 
	having grouping(a) = 1 or grouping(b) = 0

select case when grouping(a) = 1 then '合计' else cast(a as varchar) end a,
       case when grouping(b) = 1 then '总计' else cast(b as varchar) end b,
       isnull((case when grouping(c) = 1 and grouping(b)=0 then '小计' else cast(c as varchar) end),'') c,
       sum(d),sum(e) from #t 
	group by a,b,c with rollup
