关于sql表转换问题

用sql把上面的表 换成 下面的表。 

直接使用行转列 unpivot

with t as (
    select '06-07' a,1 b,0.1 c,0.1 d,0.1 e
    union all select '06-06',2,0.2,0.2,0.2
    union all select '06-07',2,0.3,0.3,0.3
    union all select '06-06',1,0.4,0.4,0.4
)
select a,col+'-'+convert(varchar,b) [n-b],b,cde 
from t a
unpivot(cde for col in (c,d,e)) p
