You will get this if you use the older DBD::Sybase. I struggled with this
stuff and made ugly workarounds just get stuff undef through a placeholder
with DBD::Sybase 0.21. Either switch to 0.91 or check for an undef value
and do a $dbh->quote() on it... unfortunately, you won't be able to use
placeholders and you'll be stuck using a stored procedure to do a lousy
insert. I HIGHLY recommend you use the latest DBD::Sybase module and at
least DBI 1.14.
