[ic] $Sql{orderline} fails?

[Grant]

I have a usertag I've been using for a while which creates a PDF file
of an order.  This morning I was making some modifications to it, and
it stopped working with "Couldn't get orderline handle" in the
error.log.  I restored the original file, but it still fails with that
error, even after rebooting the machine.  Here is the pertinent code:

my $dbh = $Sql{orderline} or die "Couldn't get orderline handle\n";

The orders table is still being read and written to just fine.  Does
anyone know what causes a line like the above to fail?
