Usage Notes

FNC_GetXMLBlob is used to get a LOB locator for the BLOB representation of the XML type. The BLOB will be in the UTF-8 encoding.

The XML handle xmlHandle is passed as input. The LOB locator value xmlBlob is returned from the function. You can then use LOB FNC routines to read from the xmlBlob locator.

Note that the BLOB representation of the XML can contain XML data that is not well-formed.

FNC_GetXMLBlob can only be used with LOB-based XML values, otherwise you will get an error.
