Hello Adam,
thank you.I am totally new to DB access using perl. I have looked at perl DBI
and DBIx::Class. I can get up to speed on DBI comparatively easily i guess.
(But), i want to start and stick to DBIx::Class, as i want to eventually use
Catalyst. Catalyst prefers DBIx::Class, so wanted to start from it.
when i saw CPAN for both I understood DBI methods easily and clearly compared
to DBIx.
use DBI; $dbh = DBI->connect($dsn, $user, $password, { RaiseError => 1,
AutoCommit => 0 });
where as in comparison i do not see (even in your example below) anything
similar in DBIx case. (like) use DBIx::Class; ... etc.
hence the confusion.
I am so new with using perl with DBI, I have no code yet written (sorry).
Hence I was looking for something simple. which fetches data from tables, uses
it and then stores some data into tables. as cgi script.
thank you.
Rajeev

I recently used DBIx::Class in a very simple command-line script that
reads files from the filesystem and stuffs them into the database.
I looked roughly like this:
#!/usr/bin/perl
use strict;
use warnings;
use utf8;
use File::Slurp qw(slurp);
use MessageID::DB;
my $schema=MessageID::DB->connect('dbi:Pg:dbname=message-id', 'USER',
'PASSWD', { AutoCommit=>1, pg_enable_utf8=>1 });
my $transaction=sub {
while(my $filename=<>) {
chomp $filename;
my $article=slurp($filename);
my $message_id=extract_message_id($article, $filename);
$schema->resultset('Article')->create({ message_id=>$message_id,
article=>$article });
}
};
$schema->txn_do($transaction);
It is trivial, but you asked for something that doesn't use Catalyst and
is small (I left out the helper-sub and the error-checking) :-)
Maybe if you show what you have tried and describe what you wanted, it
is easier to get help.
Best regards,
Adam
