Answer 1

this should give you the results you want.

CREATE TABLE #temp
(
    id int,
    data varchar(50),
    section varchar(50)
)
insert into #temp values(1, '1AAA', 'AAA')
insert into #temp values(1, '1BBB', 'BBB')
insert into #temp values(1, '1CCC', 'CCC')
insert into #temp values(2, '2AAA', 'AAA')
insert into #temp values(2, '2BBB', 'BBB')
insert into #temp values(2, '2CCC', 'CCC')
insert into #temp values(3, '3AAA', 'AAA')
insert into #temp values(3, '3BBB', 'BBB')
insert into #temp values(3, '3CCC', 'CCC')

select id, [AAA] as Column_AAA, [BBB] as Column_BBB, [CCC] as Column_CCC
from 
(
    select id, data, section
    from #temp
) x
PIVOT
(
    max(data)
    FOR section IN([AAA], [BBB], [CCC])
) as p

drop table #temp

Results:

id  column_AAA column_BBB   column_CCC
1   1AAA        1BBB        1CCC
2   2AAA        2BBB        2CCC
3   3AAA        3BBB        3CCC
