I am trying to get the all records which are 2 hours or more old using this query:

$minutes = 60 * 2

SELECT COUNT(id) AS TOTAL, job_id 
  from tlb_stats 
 W

    Try:

    $minutes = 60 * 2
    
    SELECT COUNT(`id`) AS `TOTAL`, `job_id` 
      FROM `tlb_stats` 
      WHERE `log_time` < DATE_SUB(NOW(), INTERVAL $minutes MINUTE) 
      GROUP BY `job_id`
    
    • use backticks to quote fields (words like "total" and "id" may someday mean something in MySQL)
    • use NOW() for CURRENT_DATE just means 2010-08-04, not including the time
    • use < to get entries older than that date.
