finish only works on statement handles. To get a statement handle for the
code you are using below, you'd want to do the following:
my $sth = $dbh->prepare("UPDATE $TableName SET rl = ? WHERE ID = ?");
And for the select it would look like:
my $sth = $dbh->prepare("SELECT COUNT(*) FROM $TableName WHERE ID = ? AND !rl");
my ($rv) = $sth->fetchrow_array();
Of course I'd only recommend making these changes if you need/want the
extra functionality/error handling that can be achieved with them.
Otherwise I'd stick with your method witht the change noted below.

Put parenthesis around the $rv in this statement:
($rv) = $dbh->selectrow_array("...");
If you don't then $rv is going to have the number of elements in the array
that selectrow_array returned.
