Scripting

Let me preface this with the declaration that I have absoluely no knowledge of SQL whatsoever, aside from knowing that just looking at it gives me a headache. That being said, One of the functions that would lead my organization towards using the KACE service desk module would be the ability to "focus" new ticket notification emails towards the IT persons most likely to resolve them. Towards such an end, I found an article on the Kace KB about ticket rule notifications for newly created tickets, and modified it to match our criteria:

   SELECT
      -- ticket fields
      HD_TICKET.ID, -- $id
      HD_TICKET.ID AS TICKNUM, -- $ticknum
      HD_TICKET.TITLE, -- $title
      DATE_FORMAT(HD_TICKET.CREATED,'%b %d %Y %I:%i:%s %p') AS CREATED, -- $created
      DATE_FORMAT(HD_TICKET.MODIFIED,'%b %d %Y %I:%i:%s %p') AS MODIFIED, -- $modified
      -- change fields
      C.COMMENT, -- $comment
      C.DESCRIPTION, -- $description
      GROUP_CONCAT(CONCAT('----- Change by ', UPDATER.EMAIL,' at ',H.TIMESTAMP,' -----\n',
       H.DESCRIPTION,'\n',H.COMMENT,'\n\nPlease see your ticket at http://vk1000.company.local/userui/ticket.php?ID=',H.HD_TICKET_ID,'\n')
       ORDER BY H.ID DESC SEPARATOR '\n') HISTORY, -- $history
      -- about the updater
      UPDATER.USER_NAME AS UPDATER_UNAME, -- $updater_uname
      UPDATER.FULL_NAME AS UPDATER_FNAME, -- $updater_fname
      UPDATER.EMAIL AS UPDATER_EMAIL,     -- $updater_email
      IF(UPDATER.FULL_NAME='',UPDATER.USER_NAME,UPDATER.FULL_NAME) AS UPDATER_CONDITIONAL, -- $updater_conditional
      -- about the owner
      OWNER.USER_NAME AS OWNER_UNAME, -- $owner_uname
      OWNER.FULL_NAME AS OWNER_FNAME, -- $owner_fname
      OWNER.EMAIL AS OWNER_EMAIL,     -- $owner_email
      IFNULL(OWNER.USER_NAME,'Unassigned') OWNER_USER, -- $owner_user
      -- about the submitter
      SUBMITTER.USER_NAME AS SUBMITTER_UNAME, -- $submitter_uname
      SUBMITTER.FULL_NAME AS SUBMITTER_FNAME, -- $submitter_fname
      SUBMITTER.EMAIL AS SUBMITTER_EMAIL,     -- $submitter_email
      -- about priority
      P.NAME AS PRIORITY, -- $priority
      -- about status
      S.NAME AS STATUS,   -- $status
      -- about impact
      I.NAME AS IMPACT,   -- $impact
      -- about category
      CAT.NAME AS CATEGORY, -- $category
      -- other fields
      -- -- static distribution list
      'asevera@email.com,testone@email.com,testtwo@email.com' AS NEWTICKETEMAIL -- $newticketemail
    FROM HD_TICKET
     /* latest change ***/ JOIN HD_TICKET_CHANGE C ON C.HD_TICKET_ID = HD_TICKET.ID
                            AND C.ID=<CHANGE_ID>
     /* complete history*/ JOIN HD_TICKET_CHANGE H ON H.HD_TICKET_ID = HD_TICKET.ID
     /* priority ********/ JOIN HD_PRIORITY P ON P.ID=HD_PRIORITY_ID
     /* status **********/ JOIN HD_STATUS S ON S.ID=HD_STATUS_ID
     /* impact-severity */ JOIN HD_IMPACT I ON I.ID=HD_IMPACT_ID
     /* category ********/ JOIN HD_CATEGORY CAT ON CAT.ID=HD_CATEGORY_ID
     /* owner ***********/ LEFT JOIN USER OWNER ON OWNER.ID = HD_TICKET.OWNER_ID
     /* submitter *******/ LEFT JOIN USER SUBMITTER ON SUBMITTER.ID = HD_TICKET.SUBMITTER_ID
     /* updater *********/ LEFT JOIN USER UPDATER ON UPDATER.ID = C.USER_ID
    WHERE
     C.DESCRIPTION LIKE 'TICKET CREATED%'
     AND
     CAT.NAME IS 'Hardware'
      /* this is necessary when using group by functions */
    GROUP BY HD_TICKET.ID
    HAVING 1=1

However this doesn't actually work. I believe the failure point is the additional entry I made at the bottom, as without that snippet, the rule works correctly and emails the distribution list on the creation of any ticket.

     AND
     CAT.NAME IS 'Hardware'

What I'd like to know is how I can modify this to notify only on creation of tickets in a specific category (I've got the usual, hardware, software, printer, network plus a few more prominent issues we deal with for specific software packages.

Any help would be greatly appreciated, since I'm learning all this by doing.
