A workaround you can apply right now is to have another query that queries the original one and counts the row. Then you can simply alert if the count is

UNION'd my normal query with a dummy
SELECT returning a single null row (whatever that logically means in your application). Thus, the query always returns something, and is never “unknown”. Then, the alert can trigger on there being any rows that match a test for “real data”.
