------解决方案--------------------
生成的語句格式如下:
select
[状态]=isnull([状态],'ToTal'),
[40A]=sum(case when [TYPE]='40A' then 1 else 0 end),
[40B]=sum(case when [TYPE]='40B' then 1 else 0 end),
[40C]=sum(case when [TYPE]='40C' then 1 else 0 end)
from #T group by [状态] with rollup;
------解决方案--------------------
create table [tb]([TYPE] varchar(10),[状态] varchar(10))
insert [tb]
select '40A','好' union all
select '40B','好' union all
select '40B','好' union all
select '40C','好' union all
select '40A','好'
declare @s varchar(max)=''
select @s=@s+','+quotename([TYPE])+'=sum(case when [TYPE]='+quotename([TYPE],'''')+' then 1 else 0 end)'
from [tb] group by[TYPE]
set @s = 'select isnull([状态],''ToTal'')'+@s+' from (select * from [tb] union all select ''x'',''坏'' union all select ''x'',''好'') t group by [状态] with ROLLUP'
exec(@s)
