DESCRIPTION

This Catmandu::Importer can be used to access data stored in a relational database. Given a database handle and a SQL query an export of hits will be exported.

CONFIGURATION

dsn

Required. The connection parameters to the database. See DBI for more information.

Examples:

      dbi:mysql:foobar   <= a local mysql database 'foobar'
      dbi:Pg:dbname=foobar;host=myserver.org;port=5432 <= a remote PostGres database
      dbi:SQLite:mydb.sqlite <= a local SQLLite file based database mydb.sqlite
      dbi:Oracle:host=myserver.org;sid=data01 <= a remote Oracle database

Drivers for each database need to be available on your computer. Install then with:

    cpanm DBD::mysql
    cpanm DBD::Pg
    cpanm DBD::SQLite
    cpanm DBD::Oracle
