UNPIVOT SQL的列查询

Question

我有表Price：

WhseKey ItemKey CurrID Sheet1Price Sheet2Price Sheet3Price Sheet4Price 
24  452  USD  14.90000  14.90000 13.70000  12.50000 11.03000 
24  453  USD  1.15000  1.15000 1.05000  0.95000  0.85000 
24  454  USD  12.95000  12.95000 11.90000  10.88000 9.70000 
24  459  USD  3.95000  3.95000 3.65000  3.30000  2.92000 

我想要的结果是这样的：

CurrID Name ID 
USD Sheet1Price Sheet1Price 
USD Sheet2Price Sheet2Price 
USD Sheet3Price Sheet3Price 
USD Sheet4Price Sheet4Price 

目前查询：

select UPV.CurrID , UPV.Name 
from Price 
unpivot 
(
    Name 
    for Price in (Sheet1Price, Sheet2Price, Sheet3Price, Sheet4Price) 
) UPV; 

但结果是不正确的，它来作为：

CurrID Name 
USD 14.90000 
USD 13.70000 
USD 12.50000 
USD 11.03000 
USD 1.15000 
USD 1.05000 
USD 0.95000 
USD 0.85000 
USD 12.95000 
USD 11.90000 

我错过了什么？

Answer 1

要输出提起你应该使用UPV.Price的名字，试试这个：

select WhseKey, ItemKey, UPV.CurrID , UPV.Name, UPV.Price 
from Price 
unpivot 
(
    Price 
    for Name in (Sheet1Price, Sheet2Price, Sheet3Price, Sheet4Price) 
) UPV;
