I'm using fetchall_arrayref to access an Oracle database. I want to retrieve all the rows retrieved by a SQL query and then use the map function to process the entire array before displaying. Now, my doc says it returns a reference to an array, and this array contains references to other arrays. That's where I'm stuck. I don't know how to access them. Here is my test code which is trying to just print the info from the query, one column at a time.

my $sql_return = $sth_tss->fetchall_arrayref;
print $CGI->p("sql_return is ", $sql_return);
foreach $row ([$sql_return]) {
   foreach $ref ([$row]) {
      foreach $field ([$ref]) {
         print $field;
      }
   }
}

At the first print print locations, I just see:

ARRAY(0x402624a0)

and the second (that is within the triply nested foreach loop) I see

ARRAY(0x402a05d0)

Note: its a different address and I'm only getting one print. I hope I'm being clear on what I want to do. Can some one help on this?
