I have not heard that there is any way to mark a particular record in SQL, you are always working with record set as a whole.
I had to do a similar task, so I do a left outer join of incoming data with the data which is already in the table, for those records which
match I bring the value of the field from the target table(it is my right side of the join) to the incoming data (it is left side of my join).
