SQL

cardno vehicleno    expirydate
12	ap20aa4779	06/18/12 11:50:06
14	ap20aa4777	06/05/12 11:20:36
14	ap20aa4777	06/15/12 10:46:20
14	ap20aa4777	06/15/12 10:49:20
14	ap20aa4777	06/15/12 10:55:06

Solution 1

This should works:

SQL

SELECT CardNo, VehicleNO, MAX(ExpiryDate) AS ExpiryDate
FROM YourTable
GROUP BY CardNo, VehicleNO
ORDER BY CardNo, VehicleNO

Solution 2

Try this:

SQL

SELECT CardNo, VehicleNo, expiryDate
     FROM YourTableName t1
     WHERE expiryDate = (SELECT MAX(expiryDate)
                     FROM YourTableName t2
                    WHERE t1.CardNo = t2.CardNo)
