在sql server中具有多個列的動態數據透視表

Question

我試圖動態地轉動表但無法獲得所需的結果。 這是創建表的代碼

 create table Report
 (
 deck char(3),
 Jib_in float,
 rev int,
 rev_insight int,
 jib_out float,
 creation int
 )

 insert into Report  values
 ('A_1',0.345,0,0,1.23,20140212),
 ('B_2',0.456,0,4,2.34,20140215),
 ('C_3',0.554,0,6,0.45,20140217),
 ('D_4',0.231,0,8,7.98,20140222),
 ('E_5',0.453,0,0,5.67,20140219),
 ('F_6',0.344,0,3,7.23,20140223)'

到目前為止編寫的代碼....這將列甲板和jib_in轉換為行，但這只是兩個行，即我在PIVOT函數下放入聚合函數的一個，我放在QUOTENAME（）中的一個

 DECLARE @columns NVARCHAR(MAX), @sql NVARCHAR(MAX);
 SET @columns = N'';
 SELECT @columns += N', p.' + QUOTENAME(deck)
 FROM (SELECT p.deck FROM dbo.report AS p
 GROUP BY p.deck) AS x;
 SET @sql = N'
 SELECT ' + STUFF(@columns, 1, 2, '') + '
 FROM
 (
 SELECT p.deck, p.jib_in
 FROM dbo.report AS p
 ) AS j
 PIVOT
 (
 SUM(jib_in) FOR deck IN ('
 + STUFF(REPLACE(@columns, ', p.[', ',['), 1, 1, '')
 + ')
 ) AS p;';
 PRINT @sql;
 EXEC sp_executesql @sql;

我需要將所有列旋轉並顯示在透視表上。 任何幫助，將不勝感激。 我是動態支點的新手。 我嘗試了很多方法來添加其他列，但沒有用！ 我知道還有其他方法請隨意提及是否還有其他方法可以做到這一點。

請使用此選項（如果您遇到排序規則問題，請更改所有3種INT數據類型）：

STATIC代碼：

SELECT HEADER, [A_1],[B_2],[C_3],[D_4],[E_5],[F_6]        
FROM    
(SELECT DECK,HEADER, VALUE FROM REPORT   
    UNPIVOT      
    ( 
    VALUE FOR HEADER IN ([JIB_IN],[REV],[REV_INSIGHT],[JIB_OUT],[CREATION])  
    ) UNPIV
) SRC     
PIVOT    
(
    SUM(VALUE) 
    FOR DECK IN ([A_1],[B_2],[C_3],[D_4],[E_5],[F_6]) 
) PIV

使用動態SQL：

DECLARE @COLSUNPIVOT AS NVARCHAR(MAX),
@QUERY  AS NVARCHAR(MAX),
@COLSPIVOT AS  NVARCHAR(MAX)

SELECT @COLSUNPIVOT = STUFF((SELECT ','+QUOTENAME(C.NAME)
FROM SYS.COLUMNS AS C
WHERE C.OBJECT_ID = OBJECT_ID('REPORT') AND C.NAME <> 'DECK'
FOR XML PATH('')), 1, 1, '')

SELECT @COLSPIVOT = STUFF((SELECT  ',' + QUOTENAME(DECK)
FROM REPORT T FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)') ,1,1,'')

SET @QUERY 
= 'SELECT HEADER, '+@COLSPIVOT+'
FROM
(
SELECT DECK,HEADER,VALUE FROM REPORT
UNPIVOT
(
  VALUE FOR HEADER IN ('+@COLSUNPIVOT+')
) UNPIV
) SRC
PIVOT
(
SUM(VALUE)
FOR DECK IN ('+@COLSPIVOT+')
) PIV'

EXEC(@QUERY)
