How do I tell if a mysql update was successful?

Question

How do I tell if a mysql update was successful?
I need to know if an update was run or if the record was not found....  is there some way that coldfusion can use that traps success/fail resoponses from mysql [linda like myquery.RecordCount ]?
basically I am trying to update a row, if no row was updated - the record must not exist so I then need to do an insert...
-any ideas?

here is the test query:
<cfquery name="qry" datasource="#application.dsn#">
     update DISC_CUST set DISC_PriceChange = '222222', DISC_TaxablePriceChange = '2222222'
     where DISC_ProdID = '1129'
</cfquery>
<cfdump var="#qry#" />
the error is "Variable  QRY is undefined."
if you remove the dump the debug results for the query show:
