I agree. You could always do a SELECT and if the record was found then
UPDATE otherwise INSERT. A little more effort than MYSQL but again I don't
believe the way MYSQL is allowing you to do it is standard.

And non-standard AFAIK.

Out of curiosity, why don't you know whether you're inserting or
updating? It always worries me when I don't know what my application is
doing.
