  'Conversion from xml to int is not supported on the connected database server'

  Any Idea?

  XML is a binary data type so it has to de-serialized into a string before it can be cast to a numeric type.

  Works because SQL Server XML data types support fragments:

  SELECT CAST('1' AS XML)

  Does not work *

  SELECT CAST(CAST('1' AS XML) AS INT)

  Works:

  SELECT CAST(CAST(CAST('1' AS XML) AS VARCHAR(100)) AS INT)

  * See "Implicit Conversions" section for map of supported implicit and explicit conversions http://msdn.microsoft.com/en-us/library/ms187928.aspx
