[Israel.pm] Class::DBI with several databases from the same script

[Gabor Szabo]

In version 0.96 of Class::DBI it can be done already, just the
documentation is a bit lacking.

Anyway here is my code.
Any corrections, ideas are welcome.


package My::DBI;
use base 'Class::DBI';
use DBI;

my %dbh;
my $current_dbh;

sub myinit {
	my ($dsn) = @_;
	if ($dbh{$dsn}) {
		$current_dbh = $dbh{$dsn};
	} else {
		$current_dbh = $dbh{$dsn} = DBI->connect_cached($dsn, $username, $password,
					{
						# defaults of Class::DBI
						RaiseError                  => 1,
						AutoCommit                 => 0,
						PrintError                 => 0,
						Taint                       => 1,
						RootClass                   => "DBIx::ContextualFetch",
					});
		if (not $current_dbh) {
			warn "Could not connect to '$dsn' $DBI::errstr";
			return 0;
		}
	}
	return 1;
}

sub db_Main {
	my $self = shift;
	return $current_dbh;
}
1;


# and in the nearby script:
My::DBI::myinit($dsn_a);
My::DBI->create(....)

My::DBI::myinit($dsn_b);
My::DBI->create(....)
