Re: Anyone using Ruby for scripting?

Not only that it is very flexible and you can use Oracle very easy with it, but you will also have access to the dozens of thousands of Perl modules you can install from CPAN that might also help you to do many things even easier.

A program that access an Oracle database could look like:

use DBI;

my $dbh = DBI->connect("dbi:Oracle:host=10.10.10.10;sid=orcl", "username", "password");

my $sth = $dbh->prepare("insert into users(name, email) values(?, ?)");

$sth->execute('John', 'me_at_host.com'); $sth->execute('Brian', 'b_at_host.net');

my $sth2 = $dbh->prepare("select name, email from users where locality=?"); $sth2->execute('Erevan');

while (my $row = $sth2->fetchrow_hashref) { print $row->{NAME}, "|", $row->{EMAIL}, "\n"; }

Or you will be able to use an ORM like DBIx::Class and after generating the Perl classes for your database schema say... MyDB::Schema using a command, you will need to use a code like:

use MyDB::Schema;

my $schema = MyDB::Schema->connect("dbi:Oracle:host=10.10.10.10;sid=orcl", "username", "password");

my $users = $schema->resultset("Users");

$users->create({
  name => 'john',
  email => 'me_at_host.com',
});

my $users_from_erevan = $users->search({locality => 'Erevan');

Then you will be able to use related data from other tables without doing other queries using something like:

while (my $user = $users_from_erevan->next) {   print $user->name, "|", $user->email, "\n";   print $user->supervisor->name;

  my $clients = $user->clients;

  while (my $client = $clients->next) {
    print $client->name;
  }
}
