I am trying to add the "Due Date" column to an existing report but cannot figure out the coding.  Can you please point me in the right direction?  I am using the following codes for my report:

-------------------------------------------------------------------------------------------------------------
SELECT HD_TICKET.ID,
    HD_TICKET.TITLE,
    HD_CATEGORY.NAME AS CATEGORY,
    HD_TICKET.TIME_OPENED,
    HD_TICKET.TIME_CLOSED,
    HD_TICKET.DUE_DATE,
    O.FULL_NAME AS OWNER_NAME,
    S.FULL_NAME AS SUBMITTER_NAME,
    HD_STATUS.NAME AS STATUS,
    HD_PRIORITY.NAME AS PRIORITY,
    HD_TICKET.CUSTOM_FIELD_VALUE2 
FROM HD_TICKET 
JOIN HD_CATEGORY ON (HD_CATEGORY.ID = HD_TICKET.HD_CATEGORY_ID)
LEFT JOIN USER O ON (O.ID = HD_TICKET.OWNER_ID)
LEFT JOIN USER S ON (S.ID = HD_TICKET.SUBMITTER_ID)
JOIN HD_STATUS ON (HD_STATUS.ID = HD_TICKET.HD_STATUS_ID)
JOIN HD_DUE_DATE  ON (HD_STATUS.ID = HD_TICKET.DUE_DATE_ID)
JOIN HD_PRIORITY ON (HD_PRIORITY.ID = HD_TICKET.HD_PRIORITY_ID)
WHERE (HD_TICKET.HD_QUEUE_ID != 5) AND ((TIMESTAMP(HD_TICKET.TIME_CLOSED) <= NOW() AND TIMESTAMP(HD_TICKET.TIME_CLOSED) > DATE_SUB(NOW(),INTERVAL 30 DAY))) AND (HD_STATUS.NAME = 'Closed')  ORDER BY CATEGORY
-------------------------------------------------------------------------------------------------------------

Thanks in advance!

JOIN HD_DUE_DATE  ON (HD_STATUS.ID = HD_TICKET.DUE_DATE_ID)
