I know this isn't exactly what you're asking, but here's an example of using two different data sources on a single schema in the same script. The example uses SQLite and AnyData but any DBI source should work.
#!perl -w
use strict;
sub run {
for my $source( qw(sqlite anydata)){
Schema->db_connect( $source );
Schema->db_drop_table;
Schema->db_make_table;
Schema->create({c1=>9,c2=>'Hi From'});
printf "%s %s!\n", Schema->retrieve(9)->c2
, Schema->db_Main->{Driver}->{Name};
}
}
package My::DBI;
use base 'Class::DBI';
my $source_name;
Ima::DBI->set_db ( 'anydata','DBI:AnyData(AutoCommit=1):','','' );
Ima::DBI->set_db ( 'sqlite' ,'DBI:SQLite:dbname=cdbi' ,'','' );
sub db_Main { my $db = 'db_'.$source_name; __PACKAGE__->$db }
sub db_connect { $source_name = lc $_[1] }
sub db_drop_table{ eval{ $_[0]->db_Main->do('DROP TABLE '.$_[0]->table
+)} }
sub db_make_table{ $_[0]->db_drop_table; $_[0]->sql_create->execute }
package Schema;
use base 'My::DBI';
__PACKAGE__->table ( 't1' );
__PACKAGE__->columns( All=>qw(c1 c2) );
__PACKAGE__->columns( Primary => qw(c1) );
__PACKAGE__->set_sql( 'create' => "CREATE TABLE t1 (c1 INT, c2 CHAR(9)
+)");
package main; run();
__END__
