Apache::Session::Serialize::Sybase - Use Storable to zip up persistent data and unpack/pack to put into Sybase-compatible image field
use Apache::Session::Serialize::Sybase; $zipped = Apache::Session::Serialize::Sybase::serialize($ref); $ref = Apache::Session::Serialize::Sybase::unserialize($zipped);
This module fulfills the serialization interface of Apache::Session by taking the data from Apache::Session::Serialize::Storable and modifying it to work with Sybase IMAGE fields. Note that you do not need to quote these values before inserting into the database, and that if you are using DBI::Sybase, you cannot use the data in a placeholder. If you use Apache::Session::Sybase as your session class, this will all get taken care of.
Apache::Session::Serialize::Storable was written by Jeffrey William Baker <jwbaker@acm.org>; the Sybase-specific data manipulation was written by Mark Landry <mdlandry@lincoln.midcoast.com> for use in an earlier version of Apache::Session::DBI::Sybase and placed here by Chris Winters <chris@cwinters.com>.
