一行转列sql题

有样本数据abc表如下：
id name score
1 se 30
2 se 40
3 se 58
1 hn 65
2 hn 47
3 hn 50
想转化成如下表样式：
表名：abc
name score1 score2 score3
se 30 40 58
hn 65 47 50


sql1

select b.name,sum(b.score1) score1,sum(b.score2) score2,sum(b.score3) score3
from (
    select a.name,
    case when id=1 then score else 0 end score1,
    case when id=2 then score else 0 end score2,
    case when id=3 then score else 0 end score3
    from abc a
    ) b
group by b.name

sql2:

select name, 
sum(case when id=1 then score else 0 end) score1,
sum(case when id=2 then score else 0 end) score2,
sum(case when id=3 then score else 0 end) score3 
from abc 
group by name

select a.name,a.score,a1.score,a2.score
from 
abc a,abc a1,abc a2
where 
a.name=a1.name and a.id =1 and 
a.name=a2.name
and a1.id = 2 and a2.id=3
