What's bugging me is

__PACKAGE__->data_type( # this bit's in Sweet
    __ROWS   => DBI::SQL_INTEGER,
    __OFFSET => DBI::SQL_INTEGER
);

should mean that

sub _bind_param { # this bit's in Class::DBI
        my ($class, $sth, $keys) = @_;
        my $datatype = $class->__data_type or return;
        for my $i (0 .. $#$keys) {
                if (my $type = $datatype->{ $keys->[$i] }) {
                        $sth->bind_param($i + 1, undef, $type);
                }
        }
}

should arrange for the damn thing to be bound correctly, as you pointed
out in your original post.

Try adding the following code somewhere (corrected as required, I'm
pre-coffee and typing straight into the e-mail) -

sub _bind_param { # in one of your classes
  my ($class, $sth, $keys) = @_;
  my $dt = $class->__data_type;
  warn "_bind_param for ${class}, binding for keys ".
    join(', ', @$keys)." against ".
    join(', ', map { "$_ => ".$dt->{$_} } keys %$dt;

  return $class->SUPER::_bind_param($sth, $keys);
}

which will maybe give us a little help. If nothing else, the output from
that plus DBI->trace output should be enough for you to duplicate the
issue in plain DBI if it does turn out to be a driver bug.

Yeah, that should work fine.

Thanks for the page and object caching stuff should be directed to
Christian Hansen, the original author of Sweet. My only contribution was
to destroy the order and beauty of his code in the process of hacking join
support into it :)
