How to find the Column Name of a Table from its Column Value in SQL Server 2005?

I have a view which returns a result as follows:

     D1      D2      D3      D1_CODE       D2_CODE      D3_CODE
    ----    ----    ----    ---------     ---------    ---------
   10.00    13.00   14.00      OD           LENGTH     THICKNESS

I created the view on the below selection query,

    SELECT 
        MKT_MRL_Detail.D1,
        MKT_MRL_Detail.D2,
        MKT_MRL_Detail.D3,
        MAS_SizeType.D1_Code,
        MAS_SizeType.D2_Code,
        MAS_SizeType.D3_Code
FROM
        MKT_MRL_Detail INNER JOIN
        STR_Item ON STR_Item.ItemID = MKT_MRL_Detail.ItemID INNER JOIN
        MAS_SizeType ON MAS_SizeType.SizeTypeID = STR_Item.SizeTypeID

I have return the view Based on the Inner Join of Two Tables. The above view returns only one row. Here, I want to find which开发者_运维问答 Column has a value 'LENGTH': I am using SQL Server 2005. Can any one please help?

My best suggestion would be to re-write the view (or possibly even the database) since this is not a very good design. However, I doubt that is possible. If it is not, here is my suggestion:

SELECT *
FROM (
SELECT D1 AS Value, D1_CODE AS Code
FROM view
UNION ALL
SELECT D2, D2_CODE
FROM view
UNION ALL
SELECT D3, D3_CODE
FROM view
) AS myInfo
WHERE Code='LENGTH'

It isn't pretty but it would get the job done.
