Returns
The returned object.
Exceptions
Trying to read a column that does not exist.

Remarks
The XmlReader object returned by GetXmlReader(Int32) does not support asynchronous operations. If you require asynchronous operations on an XmlReader, cast the XML column to an NVARCHAR(MAX) on the server and use GetTextReader(Int32) with Create(TextReader). SqlException exceptions raised from XmlReader are thrown as XmlException exceptions; check the inner exception for the SqlException. GetChars(Int32, Int64, Char[], Int32, Int32) will raise an InvalidOperationException exception when used on an object returned by GetXmlReader(Int32) when SequentialAccess is in effect.
