Hello Monks

I think I hit the wall with DBD::CSV module, it seems like it ignores most of rows in my file.

It all started as a success-story with DBD::CSV - I had some data in CSV format, and to access it I used loop and split 

while (<FILE>) {
my ($one,$two,$three..etc)=split(/,/);

}

This works... but some/most of the entries are now enclosed in "", so instead of 1 I've got "1". So I go and check if someone solved the problem... and I recall using DBD::CSV long time ago..

And it's magical, it works, the code is shorter, and works correctly... all rejoice and I go on writing app built on top of DBD::CSV..until I hit some strange problems.. It looks like some selects return empty resultset when they shouldn't... So i: 

##!/usr/bin/perl
use DBI;
tdbh = DBI->connect("DBI:CSV:")
        or die "Cannot connect: " . $DBI::errstr;
my $sth = $tdbh->prepare("select * from ofphl");
$sth->execute();
    while ($sth->fetch()) {$i++;};
    print ": $i \n";

[download]
and it says: 3494 but 
wc -l ofphl

[download]
says 164375. Something is obviously wrong here... I looked at 3494 row and few around it, and they look fine.. So after a while I returned to my old code, added 
map ( {s/\"(.*)\"/$1/;$_}) split(/,/)

[download]
and went on with coding...

I'm not sure that's how one's supposed to use map though...

Anyhoo... DBD::CSV looks like it's been dead for quite some time now.. mailing lists mentioned in documentation moved etc...

Update I received reply from the author, mailinglist users now sit at dbi-users@perl.org ( could've found it myself with google help, but still it's nice if documentation points to existing datasources ).

Text::CSV_XS seems like it solves my problem ( I just needed a convienient way of reading CSV file, not a way to work on it ).
