You could use the HAVING statement for this.
Not tested:
SELECT tour_player_score.strokes AS score, tour_scorecard_hole.par AS par
FROM `tour_player_score`, tour_scorecard_hole HAVING score-par AS
overpar WHERE tour_player_id=175 AND
tour_scorecard_hole.id=tour_player_score.scorecard_hole_id
Hmm was having before or after where (hmm)
test that also please:
SELECT tour_player_score.strokes AS score, tour_scorecard_hole.par AS par
FROM `tour_player_score`, tour_scorecard_hole WHERE tour_player_id=175
AND tour_scorecard_hole.id=tour_player_score.scorecard_hole_id HAVING
score-par AS overpar
