Answer 1

也许这个脚本将是有益的：

SELECT GUID, ClientGUID, TASK, 
STUFF((SELECT ';' + VALUE FROM YOUR_TABLE a 
WHERE b.GUID = a.GUID FOR XML PATH('')),1 ,1, '') AS NEW_VALUE 
FROM YOUR_TABLE b 
GROUP BY GUID, ClientGUID, TASK 

Answer 2

您可以使用STUFF获得期望的结果。

 STUFF((SELECT ',' + VALUE 
        FROM tablename where "put your condition here" 
        FOR XML PATH ('') ) , 1,1,'') AS value
