Dai un'occhiata al seguente esempio
CREATE TABLE #Table (
ID INT,
ColumnName VARCHAR(250),
Value VARCHAR(250)
)
INSERT INTO #Table SELECT 1,'name','Peter'
INSERT INTO #Table SELECT 1,'phone','12345678'
INSERT INTO #Table SELECT 1,'email','[email protected]'
INSERT INTO #Table SELECT 2,'name','John'
INSERT INTO #Table SELECT 2,'phone','87654321'
INSERT INTO #Table SELECT 2,'email','[email protected]'
INSERT INTO #Table SELECT 3,'name','Sarah'
INSERT INTO #Table SELECT 3,'phone','55667788'
INSERT INTO #Table SELECT 3,'email','[email protected]'
---I assumed your tablename as TESTTABLE---
DECLARE @cols NVARCHAR(2000)
DECLARE @query NVARCHAR(4000)
SELECT @cols = STUFF(( SELECT DISTINCT TOP 100 PERCENT
'],[' + t.ColumnName
FROM #Table AS t
--ORDER BY '],[' + t.ID
FOR XML PATH('')
), 1, 2, '') + ']'
SELECT @cols
SET @query = N'SELECT ID,'+ @cols +' FROM
(SELECT t1.ID,t1.ColumnName , t1.Value FROM #Table AS t1) p
PIVOT (MAX([Value]) FOR ColumnName IN ( '+ @cols +' ))
AS pvt;'
EXECUTE(@query)
DROP TABLE #Table
