SQL SERVER Unpivot on unknown number of columns

I need to modify this statement :


SELECT AC.FieldName, UDFN.AnalysisType FROM AnalysisCodes AC
INNER JOIN
(
SELECT  AnalysisType, AnlCol FROM UserDefFieldNames
UNPIVOT
(  AnalysisType
  for AnlCol in ([Anl1], [Anl2], [Anl3], [Anl4], [Anl5], [Anl14],[Anl22])
) UNPIV
) UDFN  ON AC.FieldName = UDFN.anlcol


to replace the fixed list of AnlCol columns with the column names generated by the query below.  How do I do this?  I can't get the syntax right.

SELECT COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'UserDefFieldNames' AND COLUMN_NAME LIKE 'Anl%'

Create a string with your last query (maybe order by) using the STUFF-function.
Then concatinate that into your unpivot-statement in a string. Finaly execute that dynamic sql statement.
