NAME

DBIx::DataSource::Driver - Driver Writer’s Guide and base class

CONTENTS

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 - itll be caught

         ( $new_dsn, $sql );
       }



2) Otherwise, you’ll need to write <B>create_databaseB> and <B>drop_databaseB>
class methods.



       package DBIx::DataSource::NewDatabase;

       sub create_database {
         my( $class, $dsn, $user, $pass ) = @_;

         # for success, return true
         # for failure, die (itll be caught)
       }

       sub drop_database {
         my( $class, $dsn, $user, $pass ) = @_;

         # for success, return true
         # for failure, die (itll be caught)
       }
