Scripting

We are looking to set a ticket rule or multiple rules if needed to do the following

If CUSTOM0 (date field) equals TODAY set priority to CRISIS

If CUSTOM0 (date field) equals 1 DAY FROM TODAY set priority to HIGH

If CUSTOM0 (date field) equals 2 OR MORE DAYS FROM TODAY set priority to MEDIUM

If CUSTOM0 (date field) equals 1 WEEK OR MORE FROM TODAY set priority to LOW

We have a ticket rule in place the sets the due date based on the custom field and that works fine...here is how that looks in case that helps with how to do the above situations...

Update SQL: 

update HD_TICKET as T
    set T.DUE_DATE = DATE_ADD(T.CUSTOM_FIELD_VALUE0, INTERVAL 8 HOUR)
  where 
        (T.ID in (<TICKET_IDS>))

Thank you in advance!
