Hi,

If you're using SQL Server 2008 or above, you can do it in this way:

SQL

CREATE TABLE #TempTable
  (ID      INT,
   Name    VARCHAR(50),
   xmlData XML);

INSERT INTO #TempTable (ID, Name, xmlData)
VALUES	(1, 'ABC', '<row><d1>10</d1><d2>25</d2></row>'),
	(2, 'XYZ', '<row><d1>12</d1><d2>11</d2><d3>15</d3></row>');


;WITH Data
     AS (SELECT ID,
                Name,
                xmlCol = C.value('local-name(.)', 'VARCHAR(50)'),
                [Value] = C.value('./.', 'INT')
         FROM   #TempTable
                CROSS APPLY xmlData.nodes('/row/*') AS T(C))
SELECT ID, Name, xmlCol, [Value]
FROM Data;


DROP TABLE #TempTable;

So here I'm using CTE, CROSS APPLY and XQuery to parse XML and transform the data into desired output.

Result:

XML

ID	Name	xmlCol	Value
1	ABC	d1	10
1	ABC	d2	25
2	XYZ	d1	12
2	XYZ	d2	11
2	XYZ	d3	15
