If you haven't gotten a fix for this yet, then try adding:
after your mysql_query() call. This allows you to see the exact sql you
are executing, and you will get to see the error mysql is returning.
This has helped me find something strange with what I was doing when I
could have sworn there was nothing wrong with my code.
As someone pointed out, you could have an attribute that says "optimize
the heck out of this routine", and your definition of heck would be a
parameter to the optimizer.
