尝试

DECLARE @Sql nvarchar(max),
        @DynamicColumn nvarchar(max),
        @MaxDynamicColumn nvarchar(max)

SELECT @DynamicColumn = STUFF((SELECT DISTINCT', '+QUOTENAME(CAST(Col1 AS VARCHAR(50)))
FROM #Temp  FOR XML PATH ('')),1,1,'') 
SELECT @DynamicColumn

SET @Sql='SELECT  '+ @DynamicColumn+'
            FROM
            (
            SELECT *
            FROM #Temp   o
            )AS src
            PIVOT 
            (
            MAX(Col2) FOR [Col1] IN ('+@DynamicColumn+')
            ) AS Pvt
             '
EXEC (@Sql)
PRINT @Sql

嗨，如果您了解您的查询，我认为该查询可以帮助您获得例外结果：

CREATE TABLE #TEMP (colName varchar(250), colOther varchar(250))

INSERT INTO #TEMP 
SELECT 'Desen', '2908A' UNION ALL 
SELECT 'Desen', '2908A' UNION ALL 
SELECT 'Desen', '2908A' UNION ALL 
SELECT 'Desen', '2908A' UNION ALL 
SELECT 'Ebat', '125x200 R' UNION ALL 
SELECT 'Ebat', '125x200 R' UNION ALL 
SELECT 'Ebat', '125x200 R' UNION ALL 
SELECT 'Ebat', '125x200 R' UNION ALL 
SELECT 'ZeminRengi', 'KEMIK' UNION ALL 
SELECT 'ZeminRengi', 'KEMIK' UNION ALL 
SELECT 'ZeminRengi', 'KEMIK' UNION ALL 
SELECT 'ZeminRengi', 'KEMIK' 


select Desen,Ebat,ZeminRengi
from #TEMP
PIVOT (
    MAX(colOther)
    FOR colName IN (Desen,Ebat,ZeminRengi)) AS Pvt

DROP TABLE #TEMP
