What exactly are your trying to do? Most likely empno is unique in this table and probably part of the PK... which is correct since employee names and salary may not be unique BUT your statement "(empno and salary could be the same)" is contrary to that. What you are trying to extract does not make sense because what if there are 5 John Doe's and 5 Jane Doe's each. There only distinction is empno.
