I have a table like so:

Id, Comment, LastUpdatedDate

I’m tyring to select the latest comment for that id. The table can have many comments on that id with different dates but I’m trying to get the latest date out of there. I’ve tried the following with no success:

SELECT tt.*
    FROM tagtestresultcomment tt
INNER JOIN
(
SELECT tag_id, MAX(last_update) AS MaxDateTime
FROM tagtestresultcomment
GROUP BY tag_id
) groupedtt ON tt.tag_id = groupedtt.tag_id AND tt.last_update = groupedtt.MaxDateTime
order by tag_id

Does anyone have any ideas of how to achieve this?

Thanks!

    your query code is too redundant. first

     tt.tag_id = groupedtt.tag_id AND tt.last_update = groupedtt.MaxDateTime

    it’s enough just 

     tt.tag_id = groupedtt.tag_id

    and second, it’s enough just 

    SELECT [desired field list extcept last_update and ], 
  tag_id, 
  MAX(last_update) AS MaxDateTime
FROM 
  tagtestresultcomment
group by 
 tag_id, [desired field list extcept last_update and tag_id]

    at all to achieve your objective
