This trigger would update every record in the table each time you add or update a single record… better would be:

CREATE TRIGGER UpdateFullName ON StudentHistory
FOR INSERT, UPDATE
AS
Update StudentHistory
set FullName = {fn CONCAT({fn RTRIM(FirstName)},{fn CONCAT(‘ ‘,{fn RTRIM(LastName)})})},
LastNameFirstName = {fn CONCAT({fn CONCAT({fn RTRIM(LastName)},’, ‘)},{fn RTRIM(FirstName)})}
WHERE IN
(SELECT FROM Inserted)

This will only update the records that were changed.
