Re: compare 2 values in same solumn

What exactly is the datatype of Shift_Date? What action are you
trying to take based on the comparison?

If you want to compare them inside a SELECT this might get you
started.

SELECT A.ShiftDate as LastShiftDate,
B.ShiftDate as NextToLastShiftDate
FROM (SELECT * FROM TheTable
WHERE Row_Index =
(SELECT MAX(Row_Index) FROM TheTable) as A
CROSS JOIN
(SELECT * FROM TheTable
WHERE Row_Index =
(SELECT MAX(Row_Index)-1 FROM TheTable) as B
