Double query to make a view?

I made a query that pivots a table using names from another table.  I asked the IT folks to make it into a view because there's a need to be able to query the pivoted result.  The query, which works fine, is below.  The response was that it couldn't be made into a view because it's actually 2 queries.  Is this true?  Is there a way it could be redone so that it could be used to make a view?

DECLARE @NPDColumns   VARCHAR (8000)

SELECT @NPDColumns =
          COALESCE (@NPDColumns + ',[' + cast (Description AS VARCHAR) + ']',
                    '[' + cast (Description AS VARCHAR) + ']')
  FROM [RKBBackEnd].[dbo].[lkpNPDBatch]
GROUP BY Description

DECLARE @query   VARCHAR (8000)
SET @query = '

DECLARE @NPD TABLE
             (  BatchCode     NVARCHAR (20),
                Description   NVARCHAR (20),
                Actual        FLOAT
             )

INSERT INTO @NPD (BatchCode, Description, Actual)
   SELECT a.BatchCode, b.Description, a.Actual
     FROM    [RKBBackEnd].[dbo].[tblNPDBatch] AS a
          INNER JOIN
             [RKBBackEnd].[dbo].[lkpNPDBatch] AS b
          ON a.BatchAttributeID = b.BatchAttributeID
    --WHERE BatchCode LIKE '+ CHAR(39) + '201203%' + CHAR(39)+ '

SELECT c.BatchAcceptDateTime, d.*
  FROM    (SELECT BatchCode, BatchAcceptDateTime
             FROM [RKBBackEnd].[dbo].[tblBatchInfo]) AS c
       JOIN
          (SELECT *
             FROM @NPD PIVOT (SUM (Actual)
                       FOR Description
                       IN ('
                  + @NPDColumns
                  + ')) AS P) AS d
       ON c.BatchCode = d.BatchCode
ORDER BY BatchCode'
EXECUTE (@query)

I'm not aware of any reasonable way to arrive at a VIEW through that. It doesn't seem as if a VIEW is appropriate.

I'd suggest going back to IT and asking for objects that give you the results that you need instead of asking for a specific kind of object. You might get a procedure back or a similar object. But it likely won't be a VIEW.

No, it is not possible to have dynamic column names in a view.
