轉換列使用數據透視

我想的cols轉換爲行，以適應格式的圖像行這是我的查詢：轉換列使用數據透視

哇查詢是嚴重難看。一些格式化將把文本牆變成不會讓其他人想要自殺的東西。 –

如果你可以讀它很好，否則不打擾。 –

所以我幫你格式化你的文章，你告訴我不要打擾。對於那些試圖幫助你的人來說，這不是一種很好的態度。 –

用較短的代碼替換冗長的SQL代碼後，只需生成示例數據，就可以實現實際的「轉置」操作這樣的：

create table tbl (yr int, y1ret float, y2ret float, y4grad float, y5grad float, y6grad float); 
insert into tbl VALUES (2015, 83.5, 71.4, 34.8, 54.7, 59.9), (2016, 83.6, 73.8, 33.8, 53.6, 60); 

select * from (
    select yr, col, value 
    from tbl 
    unpivot 
    (
    value 
    for col in (y1ret, y2ret, y4grad, y5grad, y6grad) 
) unpiv 

) src 
pivot 
(
    max(value) 
    for yr in ([2015], [2016]) 
) piv

這是當然的原始解決方案的適應這裏介紹：SQL transpose full table
正在運行的演示可以在這裏找到：http://rextester.com/CNYR30557

在大多數應用中，更簡單，更快速地做這種在接收環境中進行操作，即在使用PHP的後端或使用JavaScript的前端。

編輯：

爲了滿足您長時間的SQL代碼到這一點，你可以這樣做：

;WITH tbl AS (-- YOUR CODE GOES HERE -- 
) 
select * from (
    select yr, col, value 
    from tbl 
    unpivot 
    (
    value 
    for col in (y1ret, y2ret, y4grad, y5grad, y6grad) 
) unpiv 

) src 
pivot 
(
    max(value) 
    for yr in ([2015], [2016]) 
) piv

感謝您的這一點，但我沒有權限創建表。 –

你不需要創建表格。那只是一個佔位符。如果你把你的代碼放到「公用表表達式」中，那麼你可以從那裏運行整個事情。「CTE」的行爲就像一個視圖或表格。 – cars10m

啊！萬分感謝！ –
