while your description makes _no_ sense, I will try to explain.

Most literally, you can't. Try an array of hash refs:

my $sth = $dbh->prepare(<<__SQL__);
  SELECT * FROM $table;
__SQL__

$sth->execute;

my $table_data = [];
push @{$table_data}, $_ while $sth->fetchrow_hashref;

$sth->finish;

On the other hand, if you have an id column ( eg. primary key ), you could easily make it ( or any other column, for that matter ) a key in a Hash of Hashes:

my $sth = $dbh->prepare(<<__SQL__);
  SELECT * FROM $table;
__SQL__

$sth->execute;

my $table_data = {};
$table_data->{$_->{id}} = $_ while $sth->fetchrow_hashref;

$sth->finish;
[download]

Enjoy!
