I have tried pivot but cannot find the way我试过 pivot 但找不到路
select Name, [Color], [Size] from
(
select Name, [Type] , Attributes
from @temp_table ) AS sourceTable
PIVOT
(
MAX(Attributes)
FOR [Type] IN ([Color], [Size])
) as pivot_table
I just found out that there is nothing wrong in my code.我刚刚发现我的代码没有任何问题。

(
select Id, [Type] , Attribute

PIVOT
