sql with rollup grouping 使用

 

create table #t(a int,b int,c int,d int,e int)insert into #t values(1,2,3,4,5)insert into #t values(1,2,3,4,6)insert into #t values(1,2,3,4,7)insert into #t values(1,2,3,4,8)insert into #t values(1,3,3,4,5)insert into #t values(1,3,3,4,6)insert into #t values(1,3,3,4,8)insert into #t values(1,3,3,4,7)insert into #t values(2,2,2,4,5)insert into #t values(2,2,3,4,6)insert into #t values(2,2,4,4,7)insert into #t values(2,2,5,4,8)insert into #t values(2,3,6,4,5)insert into #t values(2,3,3,4,6)insert into #t values(2,3,3,4,8)insert into #t values(2,3,3,4,7)

情况一：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 a,sum(b),sum(c),sum(d),sum(e) from #t group by a with ROLLUP

SELECT CASEWHEN  GROUPING(a)=1 THEN '合计'ELSE CONVERT(VARCHAR,a) end AS a        ,SUM(b) FROM #tGROUP BY a WITH ROLLUP

 

SELECT CASEWHEN  GROUPING(a)=1 THEN '合计'ELSE CONVERT(VARCHAR,a) end AS a        ,SUM(b) FROM #tGROUP BY a WITH ROLLUP

 

select case when grouping(a)=1 then '合计' else cast(a as varchar) end a,case when grouping(b)=1 then '合计' else cast(b as varchar) end 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

 

情况三：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 a,    case when grouping(b)=1 and grouping(a)=0 then '小计' else cast(b as varchar) end 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 

 

 

另外一种显示小计的方式

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

 

 

情况四：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)=0select case when grouping(a)=1 then '合计' else cast(a as varchar) end a,    case when grouping(b)=1 and grouping(a)=0 then '小计' else cast(b as varchar) end b,    c,sum(d),sum(e) from #t group by a,b,c with rollup having grouping(a)=1 or grouping(b)=1 or grouping(c)=0

SELECT    grouping(a)=1FROM    #t     WITH ROLLUP

 

SELECT    grouping(a)=1FROM    #t     WITH ROLLUP

 

SELECT    grouping(a)=1FROM    #t     WITH ROLLUP
