I recently posted a question about querying a text file (which amused a few people) and as tilly pointed out I really need to use DBI.

I understand SQL a little, but not how to query a delimited text file.

Here's at least something to start with, but it's still miles away from a working solution. Please help point me in right direction. (I installed DBI and DBD::CSV on my server - Apache/FreeBSD).

use strict;
    use DBI;
    $dbh = DBI->connect(qq{DBI:CSV:csv_sep_char=\\|})
        or die "Cannot connect: " . $DBI::errstr;
    $sth = $dbh->prepare("SELECT * FROM info WHERE field_3 = Yes")
        or die "Cannot prepare: " . $dbh->errstr();
    $sth->execute() or die "Cannot execute: " . $sth->errstr();
    $sth->finish();
    $dbh->disconnect();

Here's the type of file I'm working with (posted again for apparently more amusement)

I have a pipe delimited text file. Looks like this:

Jimmy | yes | | | yes | yes | yes
Robert | yes | yes | | | |
JohnPaul | yes | yes | yes | yes | |
Bonzo | | | yes | yes | yes | |
How can I make a list from multiple field choices?
example - List 1 = those who have "yes" in field #2 but nothing in field #3
List 2 = those who have "yes" in field #2 and field #7
List 3 = "yes" in field #2, nothing in field #3, but yes in field #6

In reply to OK, OK, I'm taking the DBI plunge. Now what? by peppiv
