in thread Saving sql results to an array all rows?

Krambambuli I followed your example and I get all rows/results correctly. Now the only problem/thing that I do not know how to deal with is the @{$row_ref} array? If I wanted to run the sorted code which runs against an array passing it the @{$row_ref} array does not work. I get an array code ARRAY(0x9019330) on the screen here is the code that I am using currently. Thanks for the help!! 
foreach my $line (@lines) {
        $sth->execute($line, $line) or die "Can't execute SQL statemen
+t: $DBI::errstr\n";
        my @all_rows;
        while ( my $ref = $sth->fetchrow_arrayref()) {
                push(@all_rows, $ref);
        }
        foreach my $row_ref (@all_rows) {
                print "@{$row_ref}\n";
        }
}

Here is the sorting code that I use in a separate script which is what I am having trouble incorporating to the @{$row_ref} array. I am guessing that I can't use @{$row_ref} name when running my sort? Any ideas or help would be greatly appreciated. 
my @sorted = map {$_->[0]} sort {$a->[1] <=> $b->[1] || 
             $a->[2] <=> $b->[2] || $a->[3] <=> $b->[3] ||
             $a->[4] <=> $b->[4]} map {
             [$_, split(/\./, (split /\s+/, $_)[1])]} @lines;
print "$_\n" for @{$row_ref};

    Try to see if the following code might help you: 
    use strict;
use warnings;

use Data::Dumper;

my @lines
    = ( '2008-07-26 13.168.1.1 11122 3.3.3.3 80 hxxp://3.3.3.3 200 OK'
+,
        '2008-07-26 10.169.1.1 11122 3.3.3.3 80 hxxp://3.3.3.3 200 OK'
+,
        '2008-07-26 10.168.2.1 11122 3.3.3.3 80 hxxp://3.3.3.3 200 OK'

+,
      );


my @sorted
    = map { $_->[0] }
          sort { $a->[1] <=> $b->[1]
                         ||
                 $a->[2] <=> $b->[2]
                         ||
                 $a->[3] <=> $b->[3]
                         ||
                 $a->[4] <=> $b->[4]

               } map { [$_, split(/\./, (split /\s+/, $_)[1] ) ] }
                     @lines;

my @all_rows = map { [ split( /\s+/, $_ ) ] }
                   @lines;

my @sorted1
    = map { join( ' ', @{ $_->[0] } ) }
          sort { $a->[1] <=> $b->[1]
                         ||
                 $a->[2] <=> $b->[2]
                         ||
                 $a->[3] <=> $b->[3]
                         ||
                 $a->[4] <=> $b->[4]

               } map { [$_, split(/\./, $$_[1] ) ] }
                 @all_rows;

print Dumper( @sorted1 );

      Hey thanks again for the reply. I think that I may not be explaining myself in the best way, but here is the code that I have currently. 
      
my @lines = read_file('/tmp/test.txt');
chomp(@lines);

my $sql = q|select * from table_name where srcaddr = ? or dstaddr = ?|
+;
my $sth = $dbh->prepare($sql) or die "Can't prepare SQL statement: $DB
+I::errstr\n";

foreach my $line (@lines) {
        $sth->execute($line, $line) or die "Can't execute SQL statemen
+t: $DBI::errstr\n";
        my @all_rows;
        while ( my $ref = $sth->fetchrow_arrayref()) {
                push(@all_rows, $ref);
        }
        my @sorted = map {$_->[0]} sort {$a->[1] <=> $b->[1] ||
             $a->[2] <=> $b->[2] || $a->[3] <=> $b->[3] ||
             $a->[4] <=> $b->[4]} map {
             [$_, split(/\./, (split /\s+/, $_)[1])]} @all_rows;
        print "$_\n" for @sorted;
}

      The problem is that whenever I run the code I get the following shown below. I am guessing this is because I am using the array @all_rows which it doesn't know how to handle? I am saving the output/results from the SQL query to an array called @all_rows, now what I want to do is sort the data in column 2 in that array. What is the proper way to work/sort the data in the array @all_rows which contains all the sql results. Thanks again for the help.. 
      ARRAY(0x96b0d80)
ARRAY(0x96b0d80)
ARRAY(0x96b0d80)
ARRAY(0x96b0d80)
ARRAY(0x96b0d80)
ARRAY(0x96b0d80)
ARRAY(0x96b0d80)
ARRAY(0x96b0d80)
ARRAY(0x96b0d80)

      FYI if I print the @all_rows array using a foreach loop I get the proper results 
      foreach my $row_ref (@all_rows) {
          print "@{$row_ref}\n";
}

        And what happens if you replace your 
         my @sorted =...

        [download]
        with the replacement I've offered in the previous snippet... ?
