The DBI documentation says that a driver may implement the ChopBlanks
statement handle attribute, and that if it doesn't, it should return undef.

AFAICT, DBD::Sybase doesn't do either of those things. You can set the
attribute, but it has no effect. That is,

$sth = $dbh->prepare($query);
print $sth->{"ChopBlanks"} = 1;

doesn't alter whether or not the elements in the list returned by
$sth->fetchrow are trimmed.

However, DBD::Sybase treats char and varchar differently, in the expected
way: char columns are blank padded; varchar are not.

HTH.
