=head1 Schema::Loader Support
-There is an experimental branch of L<DBIx::Class::Schema::Loader> that will
-allow you to dump a schema from most (if not all) versions of Sybase.
-
-It is available via subversion from:
-
- http://dev.catalyst.perl.org/repos/bast/branches/DBIx-Class-Schema-Loader/current/
+As of version C<0.05000>, L<DBIx::Class::Schema::Loader> should work well with
+most (if not all) versions of Sybase ASE.
=head1 FreeTDS
When inserting IMAGE columns using this method, you'll need to use
L</connect_call_blob_setup> as well.
+=head1 COMPUTED COLUMNS
+
+If you have columns such as:
+
+ created_dtm AS getdate()
+
+represent them in your Result classes as:
+
+ created_dtm => {
+ data_type => undef,
+ default_value => \'getdate()',
+ is_nullable => 0,
+ }
+
+The C<data_type> must exist and must be C<undef>. Then empty inserts will work
+on tables with such columns.
+
+=head1 TIMESTAMP COLUMNS
+
+C<timestamp> columns in Sybase ASE are not really timestamps, see:
+L<http://dba.fyicenter.com/Interview-Questions/SYBASE/The_timestamp_datatype_in_Sybase_.html>.
+
+They should be defined in your Result classes as:
+
+ ts => {
+ data_type => 'timestamp',
+ is_nullable => 0,
+ inflate_datetime => 0,
+ }
+
+The C<<inflate_datetime => 0>> is necessary if you use
+L<DBIx::Class::InflateColumn::DateTime>, and most people do, and still want to
+be able to read these values.
+
+The values will come back as hexadecimal.
