Question

I am having a struggle with displaying data properly on the page. I am running a query for a billing report that searches all outstanding bills and I want to display them on a single page with the outstanding balance being displayed by how old the balance is. So if client ABC has 10 invoices over the past year and some of them have outstanding balances, I would like to display those balances in columns of 0-30 / 30-60 / 60-90 / and 90+ days old. Here is what I have…

    $sql17 = "SELECT $mysql_billing.primary_key, $mysql_billing.a_name, $mysql_billing.invoicedate, $mysql_billing.finaltotal, $mysql_billing_dates.paidtotal,
 ($mysql_billing.finaltotal - $mysql_billing_dates.paidtotal) AS total
 FROM
   (SELECT $mysql_billing.primary_key, $mysql_billing.a_name, $mysql_billing.login_username, $mysql_billing.invoicedate,
   SUM($mysql_billing.custotal) AS finaltotal 
   FROM $mysql_billing where $today >= invoicedate AND $start_search_prev180_date <= invoicedate AND custotal != payments GROUP BY login_username) $mysql_billing 
 LEFT JOIN 
   (SELECT $mysql_billing_dates.id, $mysql_billing_dates.username, 
   SUM($mysql_billing_dates.amount) AS paidtotal 
   FROM $mysql_billing_dates where complete != 'yes' GROUP BY username) $mysql_billing_dates 
 ON ($mysql_billing.login_username = $mysql_billing_dates.username) 
 GROUP BY a_name ORDER BY a_name ASC";

this seems to print out the results but how do you get the results into different columns based off of more than 1 date variable? Do I have to do 4 separate queries?

Your SQL Fiddle was close, but a few of your joins were incorrect.

SELECT 
  billing.a_name, 
  billing.finaltotal, 
  billing_dates.paidtotal,
  (billing.finaltotal - billing_dates.paidtotal) AS total,
   billing.TimePeriod
FROM
   (SELECT 
      a_name, 
      login_username, 
      SUM(custotal) AS finaltotal,
      CASE 
        WHEN invoicedate > DATE_SUB(CURDATE(),INTERVAL 30 DAY) THEN '30'
        WHEN invoicedate > DATE_SUB(CURDATE(),INTERVAL 60 DAY) THEN '60'
        WHEN invoicedate > DATE_SUB(CURDATE(),INTERVAL 90 DAY) THEN '90'
        ELSE '90+'
      END AS TimePeriod

    FROM billing 
    where CURDATE() >= invoicedate 
      AND CAST(20120601 AS DATETIME) <= invoicedate 
    GROUP BY login_username) billing 
 LEFT JOIN 
   (SELECT 
      username, 
      SUM(amount) AS paidtotal 
    FROM billing_dates
    GROUP BY username) billing_dates 
   ON (billing.a_name = billing_dates.username) 
ORDER BY a_name ASC;

Here is the updated Fiddle.
