Didn't mean to make it sounds like I'm an advocate for HT over TT2. I recognize the power TT2 provides, and I like what you can do with it. Just wish you could pass it arrays directly from Perl.

My MySQL query looks like this:

# issue query
my $sth = $dbh -> prepare("SELECT uid, fname, lname FROM users") || &b
+ail_out("Error: cannot prepare DB query");
$sth -> execute() || &bail_out("Error: cannot execute DB query");

The following loop yields an array with all relevant keys and values as individual elements. The results are printed to the terminal for testing:

while (@rray = $sth -> fetchrow_array) {
    $row{uid} = $rray[0];
    $row{fname} = $rray[1];
    $row{lname} = $rray[2];
    push @rows, %row;
}

foreach (@rows) {
    print "$_\n";
}

This next variation is an attempt to build a hash instead of an array. It only builds one column (lname) from the table at this time. Keys are defined as records.

while (@rray = $sth -> fetchrow_array) {
    $record = "record_$i";
    $hash{$record} = $rray[1];
    $i += 1;
}

my ($key, $value);

while (($key, $value) = each(%hash)) {
    print "key = $key, value = $value\n";
}

The two pieces of code above work. Finally, however, my attempt to build a HoH is failing. Here is what I have so far:

while (@rray = $sth -> fetchrow_array) {
    $record = "record_$i";
    $hash1{fname} = $rray[1];
    $hash2{$record} = %hash1;
    $i += 1;
}

while (($key, $value) = each(%hash2)) {
    print $hash2{$value} -> {fname};
}

There are obviously some problems here. Can you offer me some guidance?

Thanks!
