Answer 1

如果您使用的是SQL服務器意味着透視表如下用途：

CREATE TABLE #Table(Code VARCHAR(1), Description VARCHAR(15)) 

INSERT INTO #Table(Code , Description) 
SELECT 'A','Apple' UNION ALL 
SELECT 'B','Ball' UNION ALL 
SELECT 'C','Cat' 

SELECT * 
FROM 
(
    SELECT Code , Description 
    FROM #Table 
) A 
PIVOT 
(
    MAX(Code) FOR Description IN ([Apple],[Ball],[Cat]) 
)pvt 

編輯：對於動態ic pivot

DECLARE @DynamicString VARCHAR(MAX) = '' , @DynamicPvt VARCHAR(MAX) = '' 

SELECT @DynamicString = 
(
    SELECT STUFF ((SELECT ',' + RTRIM(Description) FROM #Table FOR XML 
    PATH('')),1,1,'') 
) 

SET @DynamicPvt = 'SELECT * 
FROM 
(
    SELECT Code , Description FROM #Table 
)A 
PIVOT 
(
    MAX(Code) FOR Description IN ('+@DynamicString+') 
) 
PVt' 

EXEC (@DynamicPvt)
