group by with where clause

Recommended Posts

My Oracle table columns are: message_id, status, start_time


There is no primary key. There are multiple rows for each message_id.


I would like to be able to select records where the record that has the mininum start_time value for records grouped by message_id has a status value of 'PC'

I don't think that is going to work.

I only want the records where the min(start_time) for records grouped by message_id has a status value of 'PC'

I was able to get a result with the following. Is there a better way to do this?


select message_id from table where start_time in

(select min(start_time) from table group by message_id)

and status = 'PC'
