-DBIx::Class::Storage::DBI::Sybase - Storage::DBI subclass for Sybase
+DBIx::Class::Storage::DBI::Sybase - Sybase support for DBIx::Class
=head1 SYNOPSIS
But your queries will be cached.
-You need at least version C<1.09> of L<DBD::Sybase> for placeholder support.
-Otherwise your storage will be automatically reblessed into C<::NoBindVars>.
+You need a version of L<DBD::Sybase> compiled with the Sybase OpenClient
+libraries, B<NOT> FreeTDS, for placeholder support. Otherwise your storage will
+be automatically reblessed into C<::NoBindVars>.

Your version of Sybase potentially supports placeholders and query caching,
-however your version of DBD::Sybase is too old to do this properly. Please
-upgrade to at least version 1.09 if you want this feature.
+however you seem to be using FreeTDS which does not (yet?) support this.
+
+Please recompile DBD::Sybase with the Sybase OpenClient libraries if you want
+these features.
-TEXT/IMAGE column support will also not work in older versions of DBD::Sybase.
+TEXT/IMAGE column support will also not work under FreeTDS.
See perldoc DBIx::Class::Storage::DBI::Sybase for more details.
