Yes.  If you look at the reference documentation for prepared statements,
or at the header it's generated from (prepared_statement.hxx), you'll see
that there are two ways to pass a null parameter:

1. Pass a null pointer instead of a string (but make sure it's statically
typed as a string pointer; under C++ rules an argument of "NULL" would be
interpreted as an int).

2. Pass a second, optional Boolean argument to indicate whether the
parameter is to be non-null.
