podzapytanie + UNION Opcje

[beel]

Witam!
Mam tabele:

STUDENT
student_id
name
sex


SCORE
student_id
event_id
score

EVENT
event_id
date
type

I teraz mam do wyświetlenia osobe która zdobyła najwiecej i osobe ktora zdobyla najmniej punktów, wiec:

[SQL] pobierz, plaintext 
SELECT name, type, score, sex FROM student, score, event 
WHERE student.student_id=score.student_id AND event.event_id=score.event_id AND score=
 
(SELECT max(score) FROM score, event, student 
WHERE event.event_id=score.event_id)
 
UNION
 
SELECT name, type, score, sex FROM student, score, event 
WHERE student.student_id=score.student_id AND event.event_id=score.event_id AND score=
 
(SELECT min(score) FROM score, event, student 
WHERE event.event_id=score.event_id) ORDER BY score
[SQL] pobierz, plaintext 

I w efekcie jest wyświetlany poprawny wynik. (jakby ktos umial inaczej - prosciej to wykonac prosze zademonstrowac)
A teraz drugie zapytanie:
Który mężczyzna (oznaczenie 'M') uzsykał najwiecej z ktory najmniej punktów z testu (oznaczenie 'T'):

[SQL] pobierz, plaintext 
SELECT name, type, score, sex FROM student, score, event 
WHERE student.student_id=score.student_id AND event.event_id=score.event_id AND sex='M' AND type='T' AND score=
 
(SELECT max(score) FROM score, event, student 
WHERE event.event_id=score.event_id)
 
UNION
 
SELECT name, type, score, sex FROM student, score, event 
WHERE student.student_id=score.student_id AND event.event_id=score.event_id AND sex='M' AND type='T' AND score=
 
(SELECT min(score) FROM score, event, student 
WHERE event.event_id=score.event_id) ORDER BY score
[SQL] pobierz, plaintext 

Prosze o wskazanie mi co jest źle w drugim zapytaniu bo mimo ze istenieja takie osoby nie wyświetla nic poza nazwami kolumn.
