   my $dbh  = YAML::DBH::yml_dbh($conf);

      abs_db => './t/sqlite.db',
   });

DESCRIPTION

Point and shoot method of getting a database handle with only a yaml configuration file as argument.

This is meant for people learning perl who just want to get up and running. It's the simplest customizable way of getting a database handle with very little code.

This is mostly for mysql- the default driver used. The conf file may also tell to use a sqlite db instead.

SUBS

Are not exported by default.

yaml_dbh()

Argument is abs path to yaml config file. Returns database handle, this is a DBI connect object.

Optionally you may pass it a conf hashref as returned by YAML::LoadFile instead, to scan it for the parameters to open a mysql connect with, and return a database handle.

THE YAML CONFIG FILE

You basically need a text file with various parameters. We need the hostname, the username, the password, and the name of your database to connect to. We allow the names of the parameters to be all kinds of silly things like 'user', 'username', 'uname','dbuser', 'DbUsEr' .. Case insensitive. If your config file lacks hostname, we use 'localhost' by default. You can also specify 'driver', by default it is 'mysql'

In /etc/my.conf

   ---
   username: loomis
   host: localhost
   driver: mysql
   database: stuff
   password: stuffsee

Also acceptable:

   ---
   DBUSER: loomis
   DBHOST: tetranomicon
   DBNAME: margaux
   DBPASS: jimmy

Also acceptable:

   ---
   user; james
   pass: kumquat
   dbname: stuff

Also acceptable:

   ---
   username: jack
   password: aweg3hmva
   database: akira

Also acceptable to open a sqlite db:

   ---
   abs_sqlite: /path/to/sqlite.db

Or:

   --
   abs_db: /path/to/sqlite.db

CAVEATS

Tests will fail unless you have mysqld running, see README.
