现有代码
if object_id('xmlTest') is not null
DROP TABLE xmlTest
create table xmltest(
id int identity(1,1),
iyear varchar(20),
imonth varchar(20),
iamount varchar(20)
)
insert into xmlTest (iyear,imonth,iamount)
select '2010','Jan','21900' union all

select '2012','Oct','21900' union all
select '2012','Nov','22900' union all
select '2012','Dec','20800'
想得到
JAN FEB MAR APR MAY JUN JUL AU SEP OCT NOV DEC
2010
2011
2012
这样的结果应该怎么写SQL?
