I would expect what you're doing to work.  It works with the functional
interface.

What do the query logs on the server say?  Try turning full query logging
on and see what's actually getting run.

I see in another reply that you're getting a blank white screen.  This
tends to suggest that your debugging is configured wrong, or that PHP is
encountering a fatal error and coredumping or something similar.  Check
whatever logs are appropriate for evidence of this.  Check the HTTP error
log, as well as system error logs.
