I have a table of data as follows

id    status    conversation_id    message_id    date_created
1     1         1                  72            2012-01-01 00:00:00
2     2         1                  87            2012-03-03 00:00:00
3     2         2                  95            2012-05-05 00:00:00

I want to get all the rows from the table in date_created DESC order, but only one row per conversation_id. So in the case of the example data above, I would want to get the rows with id 2 and 3.

Any advice is much appreciated.
