Reader getCharacterStream() throws SQLException
A stream containing the XML data.
The format of this stream is defined by org.xml.sax.InputSource, where the characters in the stream represent the Unicode code points for XML according to Section 2 and Appendix B of the XML 1.0 specification.

An exception is thrown if the state is not readable. A database specific code “9752 (ERRUDFJAVAXML) <Error retrieving XML value in getCharacterStream>” is returned.
