Create a new object every time.

my $foo = Foo->retrieve(17);
print $foo->bar;
undef $foo;
my $foo = Foo->retrieve(17); # fetched again
print $foo->bar; # current value

Alternatively, you can delete a single column so it will be fetched again:


That's a private method though and is probably different in different releases.
