finishing sth using Childhandles

Is the below the correct usage for finishing still active child handles of a dbh?


foreach my $childh (@{$dbh->{ChildHandles}}) {
$childh->finish() if ($childh->{Type} eq 'st');
}


I'm getting an error when running the above code:

dbih_setup_fbav: invalid number of fields: -1, NUM_OF_FIELDS attribute probably not set right

Thanks
