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
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
