= Rails/Informix -- ActiveRecord adapter for Informix

The situation that started it all [link][].

== Rails configuration

    database: dbname@dbserver
    username: santana

== Informix configuration

* You must have a sequence for each table in the form #{tablename}_seq.


  create table customers(id serial, name varchar(40));
  create sequence customers_seq;

* BYTE/TEXT columns must allow NULLs.

== Caveats

* Prefer Informix 10 or above over Informix 9. Rails/Informix makes use of
the SKIP option for pagination, which is only available since Informix 10.
