Ok, here's a more specific question. Is there a way to generate an empty
result set?
For example, I want to test the search criteria and return an "empty" result
set (or undef) if it fails the test.
I guess this is one way, but it will mean an unnecessary trip to the
database:
sub search_rs {
my ($self, $criteria, @rest ) = @_;
return $self->validate_criteria( $criteria )
? $self->next::method( $criteria, @rest )
: $self->next::method( { 1 => 0 } );
}
validate_criteria() is a bit ugly, but that's another story.
