Have a hash (from ODBC $db->DataHash) and
want to place it into an array of hashes.  How?

while ($db->FetchRow()) {
   undef %Data;
   %Data = $db->DataHash();
   # concept  push @a, %Data;  # Yes, I know this doesn't come close.
}

Do I have to break up %Data into its key/value pair and

push @a, {key1 => value, key2 => value}

or is there a better way?
Thanks

Try this:

while ($db->FetchRow()) {
  undef %Data;
  %Data = $db->DataHash();
push @HArray, \%Data;
  # concept  push @a, %Data;  # Yes, I know this doesn't come close.
}


To get it back:

foreach $ArrElem (@HArray)
{
%HashBack = %$ArrElem;
 foreach $key (keys %HashBack)
   {
    print "$key and $HashBack{$key}\n";
   };
};
