[Dbix-class] Detecting changes after ->update(\%) ?

[Paul Makepeace]

I had a look in various places (cookbook, faq, ::resultset) and
couldn't find whether there's a way to see if any SQL would be
generated due to a call to update().

  my $rv = $obj->update(\%stuff);
  $messages->($rv->XXX ? "updated" : "unchanged");

The docs* contain an enigmatic reference to "storage_rv" (that doesn't
appear anywhere in the doc) and "true if the update succeeded or false
if no records were updated". Which is it, success or $storage_rv? :-)

Version 0.8002

Thanks -
