If you work with CSV files, you can use a dedicated module.
For example Text::CSV, Text::CSV_XS, DBD::AnyData or DBD::CSV

#!/usr/bin/perl 
use strict;
use warnings;
use DBI;

my $dbh = DBI->connect('dbi:AnyData(RaiseError=>1):');

# The default is to treat the first line
# of the file as the list of column names

# If you just want to select the women
$dbh->func( 'people', 'CSV', '/home/user1/file.csv',
    { sql => "SELECT name FROM people WHERE genre='F'" }, 'ad_import' 
+);


# Print the result as a HTML table
print $dbh->func( 'people', 'HTMLtable',
 'ad_export' );

# or save it in a file
$dbh->func( 'people', 'HTMLtable', '/home/user/mytab1.html', 'ad_expor
+t' );
