in reply to Sorting colon-delimited records

TIMTOWTDI via DBD::CSV:
use DBI; use Data::Dumper; use strict; my $dir = '.'; my $file = 'simple_csv'; my $cols = [qw(one two three)]; my $dbh = DBI->connect( "DBI:CSV:f_dir=$dir;csv_eol=\n;csv_sep_char=:;", {RaiseError=>1}, ); $dbh->{csv_tables}->{$file} = { col_names => $cols }; my $sth = $dbh->selectall_arrayref(" select one, two, three from simple_csv order by two "); print Dumper $sth;
This assumes that you are in the same directory as the CSV file and the CSV file is named 'simple_csv' - note there is no extension in the file name. Read the docs for more info. Here is the sample CSV file i used:

simple_csv

three:place3:baz
two:place2:bar
four:place4:qux
one:place1:foo
