AS in a statement

[Peter Lauri]

Best group member,

I do this query 

SELECT tour_player_score.strokes AS score, tour_scorecard_hole.par AS par,
score-par AS overpar
FROM `tour_player_score`, tour_scorecard_hole WHERE tour_player_id=175 AND
tour_scorecard_hole.id=tour_player_score.scorecard_hole_id

It gives error: [localhost] ERROR 1054: Unknown column 'score' in 'field
list'

I know where the error comes from (the tables does not have score in them),
but I want to simplify the query using the AS property, and continue in the
query us it.

This works:

SELECT tour_player_score.strokes AS score, tour_scorecard_hole.par AS par,
tour_player_score.strokes - tour_scorecard_hole.par AS overpar
FROM `tour_player_score`, tour_scorecard_hole WHERE tour_player_id=175 AND
tour_scorecard_hole.id=tour_player_score.scorecard_hole_id

But I do not want to use the long name... anyone with comments?

Best regards,
Peter
