I got the Perl loop method to work (mostly for the experience). But now I'm working on the SQL method. My code looks like:

# Connect to the database, (the directory containing our csv file(s))
my $dbh = DBI->connect("DBI:CSV:f_dir=.;csv_eol=\n;");

# Associate our csv file with the table name 'results'
$dbh->{'csv_tables'}->{'results'} = { 'file' => "psinfooutputdiskfile.
+csv"};

my @rows = $dbh->selectrow_arrayref("SELECT IP, SUM(PartitionSize), SU
+M(PartitionFree) FROM results GROUP BY IP");

print ("@rows\n"); # Just here to view output

I'm getting 

SQL ERROR: Can't find table names in FROM clause!


Execution ERROR: No command found!.

Not sure what is wrong here.

it I modify the SELECT statement to:
my @rows = $dbh->selectrow_arrayref("SELECT IP FROM results");

[download]

It works. But if I try to include a GROUP BY or SUM I get the error.
