I am running this command in sql

select ID, TASK, CreatedBy,CreateDate
from John Results group by ID, TASK, CreatedBy, CreateDate

which is returning this

20  text    user1   2008-11-07 19:10:47.230
20  text    user2   2008-11-07 17:45:17.993
24  text    user3   2008-11-07 18:58:08.727
25  text    user4   2008-11-07 20:19:01.293
36  text    user5   2008-11-10 21:31:23.610
37  text    user6   2008-11-10 21:34:09.597
38  text    user7   2008-11-10 21:35:19.660

There are two ID’s that are 20 and I am trying to get the result with the lowest date so in this example it would be

20  text    user2   2008-11-07 17:45:17.993

How would I go about doing that for all the duplicate ID’s
Thank you very much
