In VFP 9, you can do something like:
SELECT Claims.Claim_ID, MaxClaim.FromDate, Claims2.Status ;
FROM Claims ;
JOIN (SELECT Claims_ID, MAX(FromDate) AS FromDate ;
FROM Claims2 ;
GROUP BY Claims_ID) MaxClaim ;
ON Claims.Claim_ID = MaxClaim.Claims_ID ;
JOIN Claims2 ;
ON Claims2.Claims_ID = MaxClaim.Claims_ID ;
AND Claims2.FromDate = MaxClaim.FromDate
You may have to tweak that a bit, but it should give you the idea.
