Is NICADDRESS the primary key of whatever class/table the CMP_NETWORK
relationship points to?
When you set a related object (either using the hashref form { ... }
or the object form, it makes no difference) RDBO will save that object
if it does not already exist. Also, using init() is the same as
making separate methods calls. So this:
$row->init
(
CMP_NETWORK =>
{
NICADDRESS => 'a01010101011',
},
HWLASTSCANDATE => '2008012114:33:00',
);
is the same as this:
$row->CMP_NETWORK({ NICADDRESS => 'a01010101011' });
$row->HWLASTSCANDATE('2008012114:33:00');
which is also the same as this:
$row->CMP_NETWORK(MyCMPNetwork->new(NICADDRESS => 'a01010101011'));
$row->HWLASTSCANDATE('2008012114:33:00');
In all cases, when it comes time to save() $row, it sees that it's had
its related CMP_NETWORK object set, and it has to decide if it needs
to save it as a new row or update an existing row. To do that, it
needs to look up the row using a primary or unique key. If none is
set, or if no existing row with that key is found, then it does an
insert.
