                     LOB_RESULT_LOCATOR*   xmlBlob)

Syntax Elements

xmlHandle
A handle to an XML type that is defined to be a return value for a UDF/UDM or an INOUT/OUT parameter to an external stored procedure.
xmlBlob
A pointer to the LOB locator that is used to set the XML type return value.

Usage Notes

FNC_GetXMLResultBlob is used to get a result LOB locator that will be used to set the XML return value.

The XML handle xmlHandle is passed as input and a LOB locator xmlBlob is returned from the function. You can then use LOB FNC routines to set the BLOB value using the xmlBlob locator. UTF-8 encoding should be used to write to the BLOB.

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