bdb1

Synopsis

A Ruby interface to Berkeley DB distributed by Oracle

Prerequisite

  • db >= 2 (some functionnality like join are not available with db < 2.6)

For Berkeley DB 1.85 and 1.86 see bdb1

Examples

See the examples directory for code examples.

Installation

You can install this module simply by:

gem install bdb

Use the --with-db-dir=$prefix option to specify with which libdb this extension should be linked.

Notes

With bdb >= 0.5.5 `nil' is stored as an empty string (when marshal is not used).

Open the database with

"store_nil_as_null" => true

if you want the old behavior (nil' stored as \000').
