Assumption: you are using DBI.

First, I would use placeholders: 

my $SQL_UserUpdate = q(update ClassRoster set Reminded={ fn NOW() } wh
+ere idEnrollee = '?');
...
...
$stmt = $db->prepare($SQL_UserUpdate);
$stmt->execute($RS_UsersToRemind->Fields('idEnrollee')->{Value});

However, the real cause of the error is that, because your string is in single quotes, the parser is trying to resolve the stuff between "{" and "}" as a hashref. Since fn NOW() apparently has a value of undef, {undef} generates the error you are seeing. what ccn said above.
