NAME
DBIx::DataSource::Driver - Driver Writer's Guide and base class SYNOPSIS
perldoc DBIx::DataSource::Driver; or package DBIx::DataSource::FooBase; use DBIx::DataSource::Driver; @ISA = qw( DBIx::DataSource::Driver ); DESCRIPTION
To implement a driver for your database: 1) If you can create a database with an SQL command through DBI/DBD, simply provide a parse_dsn class method which returns a list consisting of the *actual* data source to use in DBI->connect and the SQL. package DBIx::DataSource::NewDatabase; use DBIx::DataSource::Driver; @ISA = qw( DBIx::DataSource::Driver ); sub parse_dsn { my( $class, $action, $dsn ) = @_; # $action is `create' or `drop' # for example, if you parse parse $dsn for $database, # $sql = "$action $database"; # you can die on errors - it'll be caught ( $new_dsn, $sql ); } 2) Otherwise, you'll need to write create_database and drop_database class methods. package DBIx::DataSource::NewDatabase; sub create_database { my( $class, $dsn, $user, $pass ) = @_; # for success, return true # for failure, die (it'll be caught) } sub drop_database { my( $class, $dsn, $user, $pass ) = @_; # for success, return true # for failure, die (it'll be caught) } AUTHOR
