           int             xmlSize)

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.
xmlBuffer
A pointer to the XML value to be set.
xmlSize
The total size in bytes of the XML value.

Usage Notes

FNC_SetXML is used to set an XML return value or OUT parameter value using a memory buffer.

The XML handle xmlHandle is passed as input along with a pointer to the XML value. The XML value must be in the UNICODE character set.

Note that the XML value that is passed to this routine must contain well-formed XML data, otherwise you will get an error.

FNC_SetXML can only be called for inline XML values, that is XML values that are less than 64K, otherwise you will get an error.
