>Trying to use SELECT TOP. Have lots of records, like this:
>
> Group1, 01/01/2001
> Group1, 02/02/2001
> Group1, 03/03/2001
> Group1, 04/04/2001
>
> Group2, 01/01/2001
> etc

>I want to get the latest three records per group. Can't get the SQL right. This doesnt't do it:-
> Select top 3 thedbf.dDATE, thedbf.cGroup FROM thedbf order by 1 descend GROUP BY thedbf.cGroup
>
>Below is a little test program.
>Can you help?
