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? :-)
"Return value will be true if the update succeeded or false if no
records were updated; exact type of success value is storage-dependent."
The exact type of success value is storage dependent, hence,
$storage_rv. For example, one storage engine might return 1; another
might return the number of rows updated.
