The problem is that the statement doesn't get marked inactive until you have
fetched the row after the last one:
# There are some rows to fetch here
$sth1->execute; # Active
...
$sth1->fetch; # Last row returned, still active
$sth1->fetch; # undef returned, now it's inactive
# No rows to fetch in this case
$sth0->execute; # Active
$sth0->fetch; # undef returned, now it's inactive
As you can see, this behaviour is necessary in order that empty result sets
can be recognised. Otherwise you'd be fetching on an inactive handle.
