Getting Guile DBI

About

guile-dbi provides a simple, generic, easy-to-use scheme/guile interface to SQL databases, such as Postgres, MySQL or SQLite.

The system is 'generic' in the sense that the same programming interface (front end) can be used with different databases. The DBI (database independent) part provides the scheme interfaces. The DBD (database dependent) plugins connect to an actual SQL server. Currently, there are DBD back-ends for Postgres, MySQL and SQLite3. Creating additional DBD back-ends requires a small amount of C coding, but is a straightforward task.

Guile-dbi is simple - which is both a blessing and a curse. For the most part, all that it does is to accept guile strings encoding SQL statements, forward these to the database, and return rows as scheme association lists. A minimal amount of translation is performed - for example, SQL floating point columns are converted to scheme floating point numbers - but there is nothing fancier than this - there is no special treatment for dates, currencies, etc. At this time, there is no support for prepared statements. Capable programmers are invited to add support for this and other missing features.
