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.
