Since
Limbic~Region's excellent response mentions
DBD::CSV but then gives an example that doesn't use it, here's an example that does use it:
#!/usr/bin/perl
use warnings;
use strict;
use DBI;
my $dbh = DBI->connect(
'dbi:CSV:', undef, undef, {RaiseError=>1,PrintError=>0}
);
$dbh->csv_tables->{Log} = { file => 'yourfile.csv' };
my( $oms_cpu_total ) = $dbh->selectrow_array("
SELECT SUM(cpu_minutes) FROM Log WHERE application = ?
",{},'OMS');
printf "Application %s used %d CPU minutes\n",
'OMS',$oms_cpu_time;
__END__
Note : you will need to change the column headings to be valid SQL column names. The easiest way is to just change spaces to underscorse, e.g. "cpu_minutes".
