php - Query in a while loop fetching stale data -


i trying (and not succeeding) run while loop query gets last row in table, uses data create new row selects last row in table again (which should row created) uses data , creates new row. should repeat until while loop no longer true.

the problem have while loop runs uses row selected first time round. same row inserted on , on until while loop false.

my question how can query refresh when while loop starts new loop?

i have tried unset() did not work , out of ideas. here while loop of code (which still in progress - still add):-

while ($total_debt > 0) {     $get_dp_accounts_list_query = "select account_id         money_debt_planner         customer_id = '".$_session['customer_id']."'         group account_id";     $get_dp_accounts_list = $db->execute($get_dp_accounts_list_query);     while (!$get_dp_accounts_list->eof) {         $get_dp_accounts_listarray[] = array('account_id'=>$get_dp_accounts_list->fields['account_id']);         $get_dp_accounts_list->movenext();     }     foreach($get_dp_accounts_listarray $acc_list) {         $get_last_dp_entry_query = "select *             money_debt_planner             customer_id = '".$_session['customer_id']."'             , account_id = '".$acc_list['account_id']."'             order line_id desc";         $get_last_dp_entry = $db->execute($get_last_dp_entry_query);          if($get_last_dp_entry->fields['end_debt_balance'] <> 0) {             // calculate interest period             $accounts_balance = $get_last_dp_entry->fields['end_debt_balance'] + $get_last_dp_entry->fields['estimated_spending'];              $min_pay = $get_last_dp_entry->fields['min_pay_amount'];             $min_pay_rate = $get_last_dp_entry->fields['min_pay_rate'];             $interest_rate = $get_last_dp_entry->fields['interest_rate'];              $int_rate = $interest_rate /100;             $int_rate_a = $int_rate + 1;             $int_value_b = $accounts_balance ;             $int_value_c = ($int_rate_a * $int_value_b) - $int_value_b .

ruby on rails - Seeing duplicate requests handled with Unicorn -

(and yes disable button when user clicks submit button). unicorn 4.8.2 ruby 1.9.3 rails 3.2.14 any great! thanks! although may not fix problem, upgrade ruby 2.0.0. there blog mentioning idea upgrade ruby 2.0.0 if using unicorn. for example: https://www.digitalocean.com/community/articles/how-to-optimize-unicorn-workers-in-a-ruby-on-rails-app specifically: if using ruby 1.9,
