How about combingin two queries with set operator EXCEPT,
if you have query A EXCEPT query B, the result would be A-B.
Select * from table A fetch first 200 rows only
Union except
Select * from table A fetch first 100 rows only

Answer / the boss
There is no correct answer to this flawed question.
In RDBMS theory a table doesn't have 'records'; it is an
UNORDERED set of tuples ("rows"), so there is no
recordnumber 100 or 200.
