IPHONE Color Black Bluetooth Yes Camera Yes 
MOTV Color Silver Bluetooth No Camera No 

Ist dies möglich mit Schwenk- oder anderen Verfahren zur Erzeugung benötigen?

Wir SQL 2005 Dank

Scripts

Create TAble TempInve(ID INT Identity(1,1),Productcode VARCHAR(40),AttName VARCHAR(40),Attval VARCHAR(50)) 
INSERT INTO TempInve 
SELECT 'IPHONE','Color','Black' UNION ALL 
SELECT 'IPHONE','Bluetooth','Yes' UNION ALL 
SELECT 'IPHONE','Camera','Yes' 


INSERT INTO TempInve 
SELECT 'MOTV','Color','Silver' UNION ALL 
SELECT 'MOTV','Bluetooth','No' UNION ALL 
SELECT 'MOTV','Camera','No' 

Answer 1

für IPHONE verwenden:

DECLARE @result VARCHAR(MAX) = 'IPHONE ' 

SELECT @result += AttName + ' ' + Attval + ' ' 
FROM TempInve 
WHERE productCode = 'IPHONE' 

SELECT @result 

, wenn Sie den Cursor und wählen Sie alle verschiedene product verwenden, können Sie leicht für all dies tun ...

Answer 2

SELECT Productcode, 
     MAX(CASE WHEN AttName='Color' THEN Attval END) AS Attval, 
     MAX(CASE WHEN AttName='Bluetooth' THEN Attval END) AS Bluetooth, 
     MAX(CASE WHEN AttName='Camera' THEN Attval END) AS Camera 
FROM TempInve 
GROUP BY Productcode 

Oder

;WITH T 
    AS (SELECT Productcode, 
       AttName, 
       Attval 
     FROM TempInve) 
SELECT * 
FROM T PIVOT(max (Attval) FOR AttName IN ([Color], [Bluetooth], [Camera])) 
     AS pvt 

Answer 3

Wenn Ihre Attributnamen ändern sich ständig oder sind nicht statisch, dann können Sie diese verwenden

declare @sql nvarchar(max); 

-- generate the column names 
select @sql = coalesce(@sql + ',', '') + QuoteName(AttName) 
from (select distinct AttName from TempInve) T; 

-- replace the column names into the generic PIVOT form 
set @sql = REPLACE(' 
select ProductCode, :columns: 
from (select Productcode, AttName, Attval From TempInve) p 
pivot (max(attval) for attname in (:columns:)) pv', 
':columns:', @sql) 

-- execute for the results 
exec (@sql)
