From what I see here, $rows is a hash reference, therefore:
use strict;
use warnings;
my $mySQL = SQLfunctions->new;
$mySQL->createSQLConnection("localhost\\Company", "Import");
my @results = $mySQL->runQuery("Select A,B from tablename;");
foreach my $row ( @results ) {
foreach my $column ( keys %{$row} ) {
printf "%s: %s\n", $column, $row->{$column};
}
}
Sorry, don't have Win32::SqlServer on a box so the code is untested.
Cheers,
Mark
