Using DBI and DBD::MySQL i bump into a little problem when i try to create a subroutine that handles all the database connections.
A normal piece of database code could look like this: 
$dbh = DBI->connect("DBI:mysql:database=db;host=host", $user, $pass);
$dbquery = 'select * from table';
$sth = $dbh->prepare($dbquery);
$sth->execute();
while (my $ref = $sth->fetchrow_hashref())
{ print $ref->{'id'};
}
$sth->finish();
$dbh->disconnect();

But if i place this in a subroutine, the sub must return the object $sth or a copy of it. I am afraid that returning $sth after the finish and disconnect will not work. Making a reference to $sth won't do much good either since it's contents will probably be gone after the finish().

How can i make this work in a subroutine? </code>
