    try this:

    SELECT DAY, [1st],[2nd],[3rd],[4th], [5th],[6th],[7th], [8th]
FROM 
    (
        SELECT Day, Period, Subject --,FromTime,ToTime
        FROM StaffTimeTableEntry
    ) up
PIVOT (Min(Subject) FOR Period IN ([1st],[2nd],[3rd],[4th], [5th],[6th],[7th], [8th])) AS pvt
order by Day

    Any column not “consumed” by the PIVOT operator will remain in the final result set, increasing its cardinality.
