You may want to select also another field from the table, for example:
Code:
SELECT EMP_NUM, MAX(POSITION), EMP_NAME
FROM TABLE
GROUP BY EMP_NUM;

This will not work. You will have to use:
Code:
SELECT EMP_NUM, POSITION, EMP_NAME
FROM TABLE T1
WHERE POSITION = (SELECT MAX(POSITION)
    FROM TABLE T2 WHERE T1.EMP_NUM = T2.EMP_NUM)
ORDER BY EMP_NUM;

(The ORDER BY is not mandatory).
