Distinct field selection?

Distinct field selection?

(OP)
Situation: I have a table structured as such:
ticket_id  date  time field2

What I am trying to do is take the table and strip out all duplicates of ticket_id, keeping the most recent according to the time field.

Of course, I can do a SELECT DISTINCT on just the ticket_id field, and I get just the ticket_id results, however, I'm having trouble being able to get the remainder of the fields like this.

Any help would be appreciated in getting this working!

RE: Distinct field selection?

select *
from t1 main
where date = (
   select max(date)
   from   t1 sub
   where main.ticket_id = sub.ticket_id )

RE: Distinct field selection?

or:

CODE

select temp.* from
(select ticket_id, date , time, field2,
rank() over (partition by ticket_id order by date desc) as rk from table) temp
where temp.rk = 1

mikerexx, your code worked perfectly! (after a minor addition to add a Time max after the Date max)

Thank you so very much!
