We run a daily report to cobble together the previous days' tickets to send off to various managers/directors for their review. For the most part, it works well, but it returns every bit of text in a custom "Description" field. This is a custom field for the client to describe the issue, and some have paragraphs of text. As you can imagine, if paragraphs of text are in that field, the reports, if created in PDF as they request, look crazy. 

I'd like to modify the report query to truncate the results from that Description field to 100 characters, but am at a total loss as to how to do so, as my query skills are pretty shaky. Any help would be greatly appreciated.

Here's the query:

 select HD_TICKET.ID, 
       HD_TICKET.TIME_OPENED,
       HD_TICKET.TITLE,
       HD_TICKET.CUSTOM_FIELD_VALUE3 as DESCRIPTION,
       HD_PRIORITY.NAME as PRIORITY, 
       HD_CATEGORY.NAME as CATEGORY, 
       HD_STATUS.NAME as STATUS, 
       ifnull((select FULL_NAME from USER where HD_TICKET.OWNER_ID = USER.ID),' Unassigned') as OWNER_NAME,
       (select FULL_NAME from USER where HD_TICKET.SUBMITTER_ID = USER.ID) as SUBMITTER_NAME
from HD_TICKET
left join HD_CATEGORY on HD_CATEGORY_ID = HD_CATEGORY.ID
left join HD_STATUS on HD_STATUS_ID = HD_STATUS.ID
left join HD_PRIORITY on HD_PRIORITY_ID = HD_PRIORITY.ID
left join HD_IMPACT on HD_IMPACT_ID = HD_IMPACT.ID
left join MACHINE on HD_TICKET.MACHINE_ID = MACHINE.ID
where HD_TICKET.TIME_OPENED > DATE_SUB(NOW(), INTERVAL 24 hour)
order by OWNER_NAME, HD_PRIORITY.ORDINAL, HD_CATEGORY.ORDINAL, HD_STATUS.ORDINAL, HD_IMPACT.ORDINAL
