When XMLDescribeType=longvarbinary, the driver returns XML data as binary data. The result set column is described with a column type of LONGVARBINARY and the column type name is xml.
Your application can use the following methods to return XML data as binary data:
ResultSet.getBytes()
ResultSet.getBinaryStream()
ResultSet.getBlob()
ResultSet.getObject()
CallableStatement.getBytes()
CallableStatement.getBlob()
CallableStatement.getObject()
The driver does not apply any data conversions to the XML data returned from the database server. These methods return a byte array or binary stream that contains the XML data encoded as UTF-8.
If XMLDescribeType=longvarchar, your application should not use any of the methods for returning binary data described in this section. In this case, the driver applies the standard JDBC binary-to-character conversion to the data, which returns the hexadecimal representation of the binary data.
