I dont never used SP_XML_PREPAREDOCUMENT and SP_XML_REMOVEDOCUMENT.Please Help me

The error description is 'Duplicate attribute.'.Could not find prepared statement with handle 0.sp_xml_removedocument:The value supplied for parameter number 1 is invalid.The statement has been terminated.

Answer 1

I guess you are getting this error because the handle has not been initialized when you are calling sp_xml_removedocument. You may try a check like below to avoid the error:

IF @iData IS NOT NULL
    EXEC sp_xml_removedocument @iData
